Fischer Tropsch Synthesis Via Biomass Derived Synthesis Gas

Oct 17, 2011
Syed Ali Gardezi
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...

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...

Modeling and Scale up of CO2-Water Pretreatment of Guayule Biomass

Oct 17, 2011
Ehsan Moharreri
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...

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...

Effect of Pressure and Heating Rate On Biomass Devolatilization and Gasification

Oct 17, 2011
Pradeep K. Agrawal
The goal of present study is to characterize the effect of pressure and heating rate on the devolatilization behavior of different biomass species. Three biomass species (southern Pine, corn stover, and switchgrass) were studied. A combination of two complementary gasification devices are utilized...

Sustainability of Biomass Crop Production

Oct 16, 2011
Shijie Liu
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...

Variability of Switchgrass, a Dedicated Bioenergy Crop

Oct 16, 2011
Paul B. Filson
The utilization of switchgrass as a dedicated energy crop is well documented in the scientific community. However, there has not been any large-scale production of switchgrass as a feedstock for the production of biofuels. In this work, three different varieties of switchgrass were grown on 600...
