Flow and Transport Properties In High-Solids Biomass Slurries

Oct 17, 2011
James J. Lischeske
Economic biochemical conversion of cellulose to sugars necessitates minimal addition of water to biomass slurries during conversion, resulting in high-solids systems. The resulting slurries are effectively wet-granular materials. These materials presents difficulties for reactor engineering, as...

Kinetics Study of Furfural Production From Cellulosic Biomass

Oct 17, 2011
Taiying Zhang
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...

Direct Coupled Catalytic Upgrading of Multi-Stage Pyrolysis Bio-Oil Vapors

Oct 17, 2011
Shaolong Wan
A two-stage pyrolysis was conducted in this work. The purpose of the multiple stages is to provide a segregated product evolution in which the vapor products maybe be more selectively treated by catalysts to improve product quality and catalyst stability in comparison to one step pyrolysis in which...

Evaluation of Alternative Fuels to Replace Coal In Cement Manufacturing

Oct 17, 2011
Steve R. Duke
A multiyear DOE-supported study was completed to identify, determine, and understand fundamental burn characteristics and properties of alternative fuel sources to replace coal for energy generation, with emphasis on impacts in cement processing. Portland cement manufacturing involves the...

A Novel Method to Harvest Microalgae Via Fungal Pelletization

Oct 17, 2011
Jianguo Zhang
Microalgae harvest contributes a large portion of cost for microalgae-to-biofuels production. Most current harvest technologies including chemical and mechanical methods are only economically feasible for production of high-value products due to the costs. In this work, we are describing a new...
