The use of biomass as a source of energy has been studied extensively inrecent years, and special attention has been paid to biomass gasification. In this study, ASPEN Plus is used to conduct technoeconomic analysis of a large biomass gasification system. A biorefinery scenario consisting of 2,000...

Biomass lignocellulose can be used as feedstock for bioethanol production, and a pretreatment is necessary for achieving high ethanol yield and economical feasibility. As a method to increase enzyme digestibility of biomass by selective delignification, alkaline hydrogen peroxide (AHP) pretreatment...

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...

In the current ecological climate there is a strong push to find a renewable energy resource to reduce the usage of fossil fuels which are depleting and are causing greenhouse gas emissions. Biorenewable materials, particularly lignocellulosic biomass, have received increased attention recently as...

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...

Furfural is an important chemical and also a building block for production of drop-in hydrocarbon fuels and can be produced from cellulosic biomass such as woody crops and bagasse by hydrolysis and dehydration with mineral acids. However, furfural yields employing current technologies are limited...

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...

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...

Lab-scale pyrolysis experiments have been performed to gain insight in the mechanisms influencing the metal behavior during carbonization of chromated copper arsenate (CCA) treated wood chips. To this end a fixed bed low temperature pyrolysis reactor and a thermogravimetric (TG) analyser have been...

Woody biomass is renewable only if sustainable production is imposed. How to evaluate the benefit of different biomass crop species on a sustainability scale is a difficult task. Site dependence and regional diversity are the most important factors, while biomass productivity determines the...
