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...

Modeling and Optimization of Algae Based Biodiesel Production

Oct 16, 2011
Soumya Yadala
Processing of biodiesel from algae biomass has attracted much interest in recent times due to many reasons. Significant amongst them are global warming and scarcity in fossil fuels. It has been suggested that this third generation biofuel, a carbon neutral alternative, is capable of meeting the...

Rule of Thumb for Reactor Design and Process Condition for Biodiesel Production

Oct 16, 2011
Masato Kouzu
The rule of thumb for reactor design and process condition for biodiesel production is introduced. The important aspect includes type of feedstock oil, catalyst selection, methanol/oil ratio, quality of the produced biodiesel. When low quality plant oil is used as the feedstock, its pre-treatment...

Biomass Pyrolysis and Gasification: Engineering Rules of Thumb

Oct 16, 2011
Michael J. Antal
In this presentation I review important findings recorded in the archival literature concerning the thermodynamics, kinetics, mechanisms, and catalysis of biomass pyrolysis and gasification that serve as rules of thumb for reactor design.

Pellets From Pretreated Biomass

Oct 16, 2011
M. Toufiq Reza
Biomass supply is complicated by diversity of feedstocks, seasonal availability, and widely distributed feedstock. The costs of biomass supply and logistics hinder commercialization for advanced fuel and power production. Hydrothermal carbonization (HTC, or wet torrefaction) is a pretreatment...

Lignin Unlocking Process Led by Termites for Efficient Carbohydrate Utilization

Oct 16, 2011
Jing Ke
Wood-feeding termites are highly effective in deconstruction of wood cell wall structure for efficient utilization of cellulose and hemicelluloses. One of the key factors for its effectual cell wall disintegration is the lignin structure modification for de-protection. In this study, we provide...

Reforming of Residual Tars and Oils From Biomass Gasification

Oct 16, 2011
Lyman Frost
One of the barriers to wider use of many kinds of biomass is the fact that they generate refractory tars and oils when gasified. These compounds cause difficulty when they are passed to downstream components in the system by causing plugging and drop in performance. The compounds can be condensed...

Low Temperature Gasification of Impregnated Biomass Feedstock

Oct 16, 2011
Foster Agblevor
Hybrid poplar biomass feedstocks were impregnated with catalysts and gasified at three different temperatures in a bubbling fluidized bed reactor. The impregnated biomass were gasified in a nitrogen atmosphere at 400 o C, 600 o C, and 800 o C. The gas yield increased with increasing temperature as...

Energy (South Texas Section March 2011 Meeting)

South Texas Section Webinar
Mar 4, 2011
Mark Holtzapple

Dr. Holtzapple will describe the challenges of providing energy to a growing world. To address energy needs, he will show how the MixAlco process converts waste biomass into bio-gasoline.

Renewable Petrochemicals From Biomass by Catalytic Fast Pyrolysis

Nov 9, 2010
George W. Huber
Lignocellulosic biomass has tremendous potential as a feedstock to make renewable fuels and petrochemicals from biomass. The current impediment to the utilization of our biomass resources is that most processes to convert biomass are not currently economical because of long residence times, the...
