Society for Biological Engineering (SBE)

SBE is a global technological community that promotes the integration of engineering with biology and realize its benefits through bioprocessing, biomedical, and biomolecular applications. SBE provides opportunities for interaction of engineers and scientists, develops products and services bring value to the broad biological engineering community, and infuses awareness of biological engineering among all functions and activities of AIChE.

Realizing the Potential of Advanced Biofuels

Oct 18, 2011
Thomas Foust
Advanced biofuels or drop-in fuels is the terminology used to refer to hydrocarbon fuels that are direct replacements or supplements for existing gasoline, diesel and jet fuels currently refined from conventional petroleum feedstocks. Drop-in fuels from biomass will need to meet all of the refinery...

Reducing Process Complexity for Cellulosic Ethanol

Oct 18, 2011
L.O. Ingram
Much of the process complexity and high capital costs associate with cellulosic ethanol (dilute acid hydrolysis as a pretreatment and enzymatic saccharification of cellulose) results from side products such as furfural, acetate, and soluble lignin compounds that inhibit the biocatalysts. Inhibitor...

Point of Use Recyclable Bioreactor System for Bio-Agricultural Applications

Oct 18, 2011
Matthew A. Robinson
Farmers have long been respected for their self-sufficiency, acting as primary producers for society. Yet as time progresses, productivity demands drive farmers to require increasing levels of technology in terms of seed strains, fertilizers and pesticides in order to remain competitive. In turn...

Structural Characterization of AHP-Pretreated Biomass

Oct 18, 2011
Muyang Li
Alkaline hydrogen peroxide (AHP) pretreatment is exceptionally well-suited to grasses, yielding high digestibilities at low enzyme loadings, while generating relatively few fermentation innhibitors. For AHP pretreatment, the question of how structural and chemical compositional changes within the...

Supercritical CO2 Extraction for Algal Biodiesel Production

Oct 18, 2011
Prafulla Dinkarrao Patil
SC-CO2 is cleaner green technology for extraction of algal lipids/oils for algal biodiesel production. This work offers an optimized method for the direct conversion (One-step) of algal biomass to biodiesel using supercritical CO 2 extraction and supercritical methanol transesterification. SC-CO 2...

Pyrolytic Pathways to Advanced Biofuels

Oct 18, 2011
R. C. Brown
Pyrolysis is the thermal conversion of carbonaceous materials in the absence of molecular oxygen to liquids, solids and gases. In the most general sense, pyrolysis can occur in an inert or reducing atmosphere or within a solvent (including water); it can occur at atmospheric or elevated pressure;...

Torrefaction of Switchgrass As a Pretreatment for Catalytic Upgrading of Pyrolysis

Oct 18, 2011
Lance Lobban
The objective of this work is to use thermal pretreatment to separate the complex bio-oil mixture to produce less complex vapor streams of products from 1. light oxygenates (small aldehydes, acids) , 2. furan derivatives, and 3. phenolics. The selective production of products by thermal treatment...
