Biojet Production From Hydrocracking of Vegetable Oil

Oct 17, 2011
Huali Wang
The development of fuels from alternative and renewable sources to replace commercial petroleum products has been a subject of increasing research in recent years. At present, there are few economically feasible processes to produce jet fuel from plant oils and animal fats, especially with non-...

Steam Reforming of Ethanol-Phenol Mixture As a Model for Biomass Tar

Oct 17, 2011
Guido Busca
Introduction Hydrogen is produced by biomasses through a variety of pyrolysis and gasification processes. Most of these processes are hampered by the coproduction of tars, a mixture of heavy compounds that may result in fouling of heat exchangers and reactors. A steam reforming step is needed to...

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...

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...
