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...

Mechanistic Modeling of Fast Pyrolysis of Cellulose to Predict Bio-Oil Composition

Oct 16, 2011
Vinu Ravikrishnan
Fast pyrolysis, a potential strategy for the production of transportation fuels from biomass, involves a complex network of competing reactions, which result in the formation of bio-oil, non-condensable gaseous species, and solid char. Bio-oil is a mixture of anhydro sugars, furan derivatives, and...

Modeling and Optimization of Algae Based Biodiesel Production

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...

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...

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.

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...
