Structural Characterization of AHP-Pretreated Biomass

Oct 18, 2011
Muyang Li
Alkaline hydrogen peroxide (AHP) pretreatment is exceptionally well-suited to grasses, yielding high digestibilities at low enzyme loadings, while generating relatively few fermentation innhibitors. For AHP pretreatment, the question of how structural and chemical compositional changes within the...

Pyrolytic Pathways to Advanced Biofuels

Oct 18, 2011
R. C. Brown
Pyrolysis is the thermal conversion of carbonaceous materials in the absence of molecular oxygen to liquids, solids and gases. In the most general sense, pyrolysis can occur in an inert or reducing atmosphere or within a solvent (including water); it can occur at atmospheric or elevated pressure;...

Comparison of Chemical and Biological Delignification of Cardboard

Oct 18, 2011
Estefania Isaza
Some processes aimed to biofuels production, use lignocellulosic wastes as feedstocks for fermentative conversion. If this is the case, pretreatment is required to make these resources fully digestible. Among a wide range of pretreatment options, this study focuses and compares oxidative-alkaline...

An Integrated Lipid-Based Platform for “Drop-In” Fuel Biorefinery

Oct 18, 2011
Shulin Chen
A major challenge in developing biorefinery is that the availability of biomass often limits the scale of the plant thus the feasibility of an operation. We proposed an integrated lipid-based platform as one technical option. According to this concept, different biomass resources will be first...

Realizing the Potential of Advanced Biofuels

Oct 18, 2011
Thomas Foust
Advanced biofuels or drop-in fuels is the terminology used to refer to hydrocarbon fuels that are direct replacements or supplements for existing gasoline, diesel and jet fuels currently refined from conventional petroleum feedstocks. Drop-in fuels from biomass will need to meet all of the refinery...

Wood Pellets Self-Heating During Storage

Oct 17, 2011
Wendi Guo
Accidental fires in wood pellets silos happen frequently in the last five years. Experiments were carried out in this work at temperature range of 100 o C to 200 o C to study wood pellets chemical oxidation process. A self-heating model was developed to simulate the self-heating process using the...

Catalytic Conversion of Biomass Into Carboxylic Acids Via APPO Process

Oct 17, 2011
Hongfei Lin
Converting raw solid biomass into liquid or gas phase intermediates which can be readily upgraded to hydrocarbon fuels is the most challenging or energy intensive step during the biofuel production process due to the complex composition and structure of biomass. We are developing cost competitive...
