Topical 6: Lignocelluosics: Biorefineries and Sustainable Energy T6007 Thermalchemical Conversion I AIChE 2011, October 16~21, 2011 Minneapolis, MN Pretreatment of Loblolly Pine for Fast Pyrolysis via Torrefaction Jiajia Meng, David Tilotta, and Sunkyu Park* Department of Forest Biomaterials, North...

Separate processing of hemicellulose and cellulose to optimize ethanol production from corn stover Alexandre Chapeaux, Nancy Dowe, Daniel J. Schell Using a series of thermochemical (pretreatment) and biochemical steps, lignocellulosic biomass is converted to sugars that subsequently can be made...

As cost associated with fossil fuels rise due to various environmental, social, and economic factors, it has become prudent to examine the possibility of exploiting alternative sources of raw materials for the production of energy and chemicals. Biomass, of various forms, has been proposed as an...

When produced from waste lignocellulosic materials, hydrogen is one of the most promising options for a long-term, net-zero emission energy carrier. A major barrier to industrial scale production of bio-H 2 is its techno-economic feasibility. Advances in consolidated bioprocessing are required to...

A carbon dioxide – water pretreatment process was developed for guayule biomass. The guayule biomass was mixed with water and then loaded to a reactor where it was exposed to a biphasic environment consisting of CO2 rich vapor phase and water rich liquid phase. Then, the biomass was enzymatically...

The first step in the conversion process of biomass to biofuels or hydrogen lies in picking an environmentally friendly solvent which is capable of breaking up the crystalline microstructure of cellulose. Once the cellulose is in suspension, enzymes (cellulases) are added to the reactor to...

Due to the recent surge in energy costs and uncertainties in fuel prices, there is significant interest in seeking alternative sources of energy particularly from renewable such as biomass. Indirect liquefaction of biomass (via the thermo-chemical conversion to syngas followed by liquefaction via...

Biodiesel is a renewable, carbon-neutral fuel that can ease pressure on the world’s dwindling supply of oil and petroleum diesel. This research explores production of biodiesel from alternative low-value feedstocks such as waste oils. Traditional biodiesel reactions mix an alcohol and a refined...

Bio-Ethanol/water separation by fractional distillation becomes a popular industrial process to remove water from ethanol-water mixture. However, the mixture of 95.6wt% ethanol and 4.4 wt% water is an azeotrope and cannot be further purified by distillation. Alternatively, this can be achieved by...
