Keynote: Potential yield of dedicated energy crops: results and outcomes of the sun grant regional feedstock partnership
Time : 10:10-10:45
Biography:
Vance Owens received BS, MS, and PhD degrees at Brigham Young University, Utah State University, and the University of Wisconsin-Madison, respectively. He is Director of the North Central Sun Grant Center and Professor of Plant Science at South Dakota State University. He has conducted research on production of bioenergy feedstock crops, specifically perennial species, for more than 20 years.
Abstract:
Statement of the Problem: The Sun Grant Regional Feedstock Partnership commenced in 2007 with the goal of supporting the realization of the biomass potential envisioned in DOE’s 2005 Billion Ton Report. Concluding in 2016, the partnership sought to increase the knowledge of bioenergy through coordinated feedstock research across the lower 48 states and Hawaii with partners in academia, government, and private industry. Methodology & Theoretical Orientation: The core of the research includes over 130 field trials and regional resource assessment activities focused on agricultural residues and a suite of likely dedicated energy crops. In 2013 a series of meetings was held across the US with each of the crop teams and the resource assessment team, led by the Oregon State University and Oak Ridge National Laboratory, to review, standardize, and verify yield trial data and assimilate their outcomes into a national model of biomass yield suitability. The meetings provided a way to “ground truth” yield estimates in order to accurately capture interactions of climate and soils for dedicated energy crops, including switchgrass, energycane, biomass sorghum, CRP mixtures, Miscanthus x giganteus, hybrid poplar, and willow. Findings: From these sets of funded trials and historical data, yield was estimated across spatial gradients according to soil characteristics and climate history (see Figure 1 for Giant Miscanthus example). The resulting spatial grids provide critical information for policymakers and planners of the potential productivity of these pre-commercial crops. National yield estimates, as well as overall yield across the continental USA, demonstrated potential for these diverse feedstock resources. Conclusion & Significance: Production and management data, as well as biomass composition characteristics, provide empirical support of logistic design and feedstock supply systems. These data and maps are vital for policy makers, producers, end-users, and others in the bioeconomy.

Session Introduction
Tony Tiyou
Renewables in Africa, UK
Title: Bioenergy industry prospects in Africa
Time : 12:15-12:45
Biography:
Tony Tiyou holds a triple Engineering Master’s Degree from Cranfield University (UK), Ecole Centrale de Lille (France) and Faculte Polytechnique de Mons (Belgium). Tony also holds qualifications as Renewable Energy expert from the European Energy Centre (UK). After having worked and held various positions and roles for about a decade in both the Automotive and the Renewable Industry, Tony has founded with a partner, a consultancy, O’wango & TT Smart (O&TT). In September 2016, he launched a blog: Renewables in Africa.
Abstract:
Background: Africa is endowed with vast renewable energy resources that can provide solutions to the severe energy issues the continent is experiencing. Among them, hydropower stands as the cheapest of all and has historically being the most exploited. Since the last decade, the continent is increasingly turning to solar PV and wind to bolster energy security and support rapid economic growth in a sustainable manner. This has been due in large part to improving technology and declining costs of equipment. In comparison, bioenergy which is currently widely used for cooking and heating is almost untapped as far as power generation is concerned.
Resources: At the difference of widespread solar, bioenergy is only present in large quantities in specific areas where rain is abundant, like Central Africa and parts of West and East Africa. Although less well-off, North Africa and Southern Africa are nevertheless looking as well at harnessing this energy to enhance the diversification of their energy mix. Across Africa, the technical potential for the use of bioenergy for power generation is estimated at 2.631 TWh, with 60% in Central Africa. Bioenergy is usually being exploited in one of its three forms: solid biomass, biogas and biofuels.
Market Opportunities: The current market in Africa is still in burgeoning stages. Investments and technologies have essentially been the main obstacles. Kenya has been experimenting biogas for few decades. Although they have been unlucky so far, they are still pursuing their development. Other countries like Senegal, Burkina Faso, Mauritania and Ethiopia have also express interest into the industry. Estimates suggest that South Africa could generate 5% of its electricity from biogas. Should it be exploited through the REIPPP, this will have the potential to transform the whole industry on the continent, like it has been the case for solar and wind.

Title: Making a bridge between biomass and hydrocarbon in a standard refinery
Time : 12:45-13:15
Biography:
Marcelo Maciel Pereira is an Associate Professor at the Chemistry Institute of Federal University of Rio de Janeiro (UFRJ - Brazil). He obtained the MSc and the Ph.D. in Chemical Engineering at Federal University of Rio de Janeiro. His research interests focus on kinetics and catalysis, hydrocarbons, biomass conversion, zeolites, CO2, greenhouse gas emissions and sequestration.
Abstract:
A conventional refinery is based on mature processes that obtain standard products from a large variety of non- renewable feeds. Despite enormous benefits to modern civilization,3 the adopted production and consumption patterns paradoxically put us at environmental risk. Therefore it is mandatory a paradigm shift to decrease the carbon footprint without reducing the energy access to people. Biomass is composed of functionalized biopolymers (lignin-cellulose) based on sugars- and phenol-derivatives. On the other hand, refinery processes have been designed to operate on poorly reactive compounds like hydrocarbons. The bridge between these two remarkable worlds was archived in two steps: 1- by transforming the biomass into a bio-crude, which was produced by ketalyzation in acetone [1, 2] and acetylation reactions in acetic anhydride [3] under mild temperature conditions (around 100oC). This black bio-crude (density around 1.0-1.3 gmL-1 and CHO composition of 60, 8 and 32 respectively) is chemically distinct of any other bio-feed so far. 2 -The transformation of bio-crude and model compounds by the fluid catalytic cracking and hydrotreatment into monoaromatic and saturated hydrocarbons respectively [4]. Herein the results of the fluidized bed pilot plant in laboratory scale of both model test and bio-crude are presented. For instance, a representative ketal-derivative, 1,2:5,6-di-O- isopropylidene-α-D-glucofuranose (DX) mixture up to 50% in n-hexane achieved three main goals: small coke formation, remarkable selectivity to hydrocarbons and slight improvement in n-hexane conversion as presented in Table 1. Moreover, no oxygenated compounds were observed in the liquid phase, thus resulting in a drop-in fraction in the fuel pool. The bio-base economy derived from this concept fits the requirements to be produced, transported and processed like wise to the up- to downstream in the oil industry. Finally, as a consequence the bio-crude behaves like hydrocarbons under realistic refinery process, oil could be partially substituted by bio-crude or, in the future; an entirely green refinery could operate using renewable feeds.

Title: Moringa oleifera crop residues as a source of bioethanol
Time : 14:00-14:30
Biography:
Miguel Godino García is a professor at the School of Forestry Engineers of the Universidad Politécnica de Madrid. He has been involved in cooperation projects in Colombia for 8 years, promoting the integral development of moringa cultivation and its different uses, focusing on the production of moringa oil. In collaboration with the University of Tolima, it is being promoted the creation of a university network with different Colombian universities opened to other universities.
Abstract:
Moringa (Moringa oleifera) is a high-productivity, fast-growing multipurpose plant adapted to dry tropical conditions. In Europe it is susceptible to grow in temperate Mediterranean areas with few frosts. As biomass, the composition of its nutrients makes it very interesting for its consumption, in green or dry, by both animals and people. Its fruits are triangular pods that provide oilseeds, with more than 30% of edible oil in its composition. Moringa pod husk are considered as a waste that, being rich in cellulose, is a source of raw material for the production of bioethanol. The management of the moringa tree crown, necessary for a good and easy harvest, provides a little lignified wood susceptible of being transformed in this biofuel. The massive production of moringa oil in tropical areas can represent an opportunity to value these residues and, with them, help combat the so-called Climatic Change together with the change of land uses and the reforestation of lands currently dedicated to extensive livestock. To explore the feasibility of using these residues for biofuels production, it´s necessary to know: the potential production of the residues obtained in a crop of moringa oil , the results of compositional analysis of stems and pods of moringa and the results obtained in the production of bioalcohol.

Title: Impact of pyrolysis temperature on the characteristics and utilization potential of bio-chars derived from wooden dust
Time : 14:30-15:00
Biography:
Shalini Gautam has more than 15 years of experience in Research & Teaching. She has her expertise in Fuel Technology, Coal characterization, Coal carbonization, Coal combustion and Gasification. Her recent area of work is on ‘Utilization potential of Indian Biomass for different thermo chemical processes like combustion, carbonization, gasification, etc.; utilization of poor quality coking coals for metallurgical applications.
Abstract:
To meet the global demand of energy, coal is the predominant source, which is depleting gradually and requires an alternative source preferably with less concern of climate change. Keeping this in view impact of pyrolysis temperatures on the characteristics of bio-chars derived from pyrolysis of the wooden dust and its utilization potential, was examined. The pyrolysis was carried out in a pyrolysis chamber at 400, 600, 800 and 1000°C for an hour, using heating @ 5-15oC/min. The obtained results evince that wooden dust can be a potential source for pyrolysis. Low temperature pyrolysis produced bio-char with high yield, but high temperature pyrolysis led to low yield bio-char with higher content of carbon and heating values. Thermal analysis of the wooden dust showed higher degradation profile that is weight loss increases with increase in temperature. Bio-chars from wooden dust particularly at temp 600-800oC can be more suitable for steelmaking, in view of their chemical and thermo-chemical characteristics including low ash, higher heating values (HHV), high surface area, etc.. In traditional iron making reduction of iron ores to metallic iron is done by coke which acts as a reductant and source of energy as well. The coal used for coke making is premium in quality and has limited reserves, so an attempt has also been made to reduce the requirements of coking coal using wooden dust char through direct reduction of iron ore.The obtained results show that highest percentage of reduction can be achieved in case of wooden dust char as compared with coal. Also kinetic study of the work shows activation energy 75.16 KJ/mole.
