A Novel Method to Harvest Microalgae Via Fungal Pelletization

Oct 17, 2011
Jianguo Zhang
Microalgae harvest contributes a large portion of cost for microalgae-to-biofuels production. Most current harvest technologies including chemical and mechanical methods are only economically feasible for production of high-value products due to the costs. In this work, we are describing a new...

Wood Pellets Self-Heating During Storage

Oct 17, 2011
Wendi Guo
Accidental fires in wood pellets silos happen frequently in the last five years. Experiments were carried out in this work at temperature range of 100 o C to 200 o C to study wood pellets chemical oxidation process. A self-heating model was developed to simulate the self-heating process using the...

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...

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...
