Title: Understanding the Flow Behavior of Cohesive Biofeedstock

Presented by: Dr. Klein Ileleji, Associate Professor, Agricultural & Biological Engineering Department, Purdue University, West Lafayette, Indiana, USA.

Date presented: July 13, 2010 at 10:00am

Abstract: Biofeedstocks such as lignocellulosic biomass (corn stover, switchgrass, etc.) and coproducts (distillers grains with solubles, DDGS) from ethanol manufacture are important feedstocks used for the production of feed, fuel and energy. Their handling in thousands of tons involve transportation, storage and feeding using rail hoppers, barges, shipping vessels and hopper silos. Unlike free flowing bulk solids, these feedstocks are very cohesive and hygroscopic, and will build strength in storage hoppers causing bridging/arching to prevent their discharge. The occurrence of bridging will result in production stoppages and down time and result in millions of dollars in lost revenue and damages. This presentation discusses research effort work on two cohesive biofeedstocks (DDGS and switchgrass). I will discuss the complexities with cohesive biofeedstocks, fundamental research and modeling efforts of my lab in the past year.

Dr. Klein Ileleji Biosketch:

Klein E. Ileleji, PhD. is an Associate Professor and Extension Engineer in Agricultural and Biological Engineering at Purdue University. Dr. Ileleji's research focus and interest at Purdue University is in the area of biomass feedstock logistics, processing, particulate flows and handling, and biofeedstock engineering systems for food, feed, fuel and fiber production. Current research activities are related to the development of logistics analysis simulation and tools for biomass feedstock, investigation of flow behavior of biologically active particulates, determination of feedstock quality parameters, feedstock processing and handling, and fuel preparation for the production of heat and power via combustion and gasification. He also has extensive research experience in post-harvest handling of grains and oilseeds, especially with respect to stored product protection. His work is published in over 20 peer-reviewed journal publications and over 60 conference papers.

Dr. Ileleji teaches Biomass Feedstock Systems Engineering (ABE591K), Electric Power and Controls (ASM420) and coordinates an on-line distance education course in fuel ethanol production administered through GEAPS-Kansas State-Purdue Distance Education Program. He has extensive international experience, and currently in collaboration with the State Key Laboratory for Clean Energy Utilization at Zhejiang University in Hangzhou, China as a visiting scholar on 111 Project. He has an extension engineer role in renewable energy in the Agricultural and Biological Engineering Department at Purdue University.

Dr. Ileleji is a 16 year member of both the American Society of Agricultural and Biological Engineers (ASABE) and International Commission of Agricultural Engineering (CIGR), and a 3 year member of the Grain Elevators and Processing Society (GEAPS). Dr. Ileleji is the committee chair for a working group (WG) charged with developing an ASABE Standard for “Determining Properties of Combustible Solid Fuels of Plant Origin (Plant Biomass)”; (X564 Committee). X564 committee is also the technical advisory group (TAG) to ISO/TC238 effort toward the development of an international standard for solid biofuels.
