From Biochemical Engineering to Synthetic Biology: A Short History of Engineering Impacts on Biotechnology

SBE Webinar

Sep 27, 2012

Harvey Blanch

This webinar will focus on how biochemical engineering developed in response to the need for large-scale production of antibiotics in the 1940s and 50s, even though fermentation provided a route to many industrial organic chemicals prior to their production from petroleum.

Effects of Ammonia Substitution On Stability Limits and Emissions of Premixed Hydrogen/Air Flames

Oct 19, 2011

Dong Hyun Um

The potential of partial ammonia (NH 3 ) substitution to improve the safety of hydrogen (H 2 ) use was evaluated, using premixed NH 3 /H 2 /air flames at normal temperature and pressure generated on a tube type burner. The effects of NH 3 substitution on the stability limits and nitrogen oxide (NO...

A Novel Reactive Distillation Approach for Producing 1,3-Dihydroxyacetone From Glycerol

Oct 19, 2011

Dennis J. Miller

Glycerol is a viable renewable feedstock that has emerged as a consequence of triglyceride conversion to biodiesel. In addition to glycerol conversion to commodity chemicals such as propylene glycol and epichlorohydrin, formation of higher-value specialty chemical products such as 1,3-...

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;...

The Production of Fuel Grade Butanol From Algal Carbohydrates Utilizing a Hybrid Biological and Chemical Process

Oct 18, 2011

Thomas M. Potts

Butanol has the potential to become a superior renewable fuel, either as a mixture with petroleum derived gasoline or as a stand-alone, neat fuel. The promise of butanol is currently marred by the relatively high cost of production. This paper explores a new and novel approach to the production of...

Alkaline Deacylation of Corn Stover to Reduce Toxicity of Prehydrolyzates and Improve Enzymatic Hydrolysis

Oct 18, 2011

Urvi D. Kothari

Hydrolysates from dilute acid pretreatment of biomass contain various biomass degradation products which are inhibitory to enzymes and toxic to microorganisms. One of the main inhibitory compounds is acetic acid which is released from the lignin-hemicellulose matrix in the biomass. Acetic acid at...

The Role of Acidic Catalyst Support On the Catalytic Upgrading of Bio-Oils

Oct 18, 2011

Sunya Boonyasuwat

Catalytic conversion of bio-oil vapor has attracted considerable interest as a promising pathway for upgrading. In this work, the reaction of anisole and guaiacol, phenolic model compounds commonly existing in bio-oils, were studied over an acidic silica-alumina catalyst and at varying space times...

Synthesis of Green Diesel Fuel From Fatty Acid Feedstocks Via Electrochemical Hofer-Moest Decarboxylation

Oct 18, 2011

Cody Wagner

Production of biodiesel by esterification or transesterification of long-chain fatty acids is a well known process, but the fuel product has characteristics making it not fully compatible with petroleum diesel engines. A better option is to convert fatty acid molecules to hydrocarbons by removing...

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...

Comparison of Chemical and Biological Delignification of Cardboard

Oct 18, 2011

Estefania Isaza

Some processes aimed to biofuels production, use lignocellulosic wastes as feedstocks for fermentative conversion. If this is the case, pretreatment is required to make these resources fully digestible. Among a wide range of pretreatment options, this study focuses and compares oxidative-alkaline...

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...

Integration of a Membrane Based Extraction Process Into a Lignocellulosic Biorefinery

Ranil Wickramasinghe

In the future, it is anticipated that multi-product biorefineries will be used to convert lignocellulosic biomass to fuels and chemicals, in which, it may be possible to use membrane-based separations to recover fuels and various products and to improve energy efficiency. To biochemically convert...

An Integrated Lipid-Based Platform for “Drop-In” Fuel Biorefinery

Oct 18, 2011
