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...

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...

Effects of Mixing Quality On the Kinetics of Biomass Liquefaction

Oct 17, 2011
David M. Lavenson
Abstract: Biochemical conversion is a promising route to produce fuels and chemicals from cellulosic biomass. A key step in the process is biomass liquefaction, where enzymes are used to break down pretreated cellulosic particles. During this process, drastic changes in the mechanical properties of...

Novel Reactor Design for Conversion of Waste Oils to Biodiesel

Oct 17, 2011
Richard A. Cairncross
Biodiesel is a renewable, carbon-neutral fuel that can ease pressure on the world’s dwindling supply of oil and petroleum diesel. This research explores production of biodiesel from alternative low-value feedstocks such as waste oils. Traditional biodiesel reactions mix an alcohol and a refined...

Synthesis of Bifunctional Catalyst for Aqueous Phase Reforming of Biomass

Oct 17, 2011
Richa Tungal
This study reports the synthesis of novel bifunctional catalytic material and its utilization in catalytic aqueous phase reforming of biomass to enhance selectivity and conversion into hydrogen and higher hydrocarbons. The synthesis involved the preparation of mesoporous aluminosilicate catalyst by...

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-...
