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...

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

Oct 18, 2011
Shulin Chen
A major challenge in developing biorefinery is that the availability of biomass often limits the scale of the plant thus the feasibility of an operation. We proposed an integrated lipid-based platform as one technical option. According to this concept, different biomass resources will be first...

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...

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...

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...

Heterogeneous Catalysts in the Dehydration of Fructose to HMF

Oct 18, 2011
Sylvia Reiche
Several crucial steps in the upgrading of biomass-derived raw materials involve acid catalyzed reactions, such as the hydrolysis of cellulose or the dehydration of sugars. Although heterogeneous catalysts are desired in large scale industrial processes, their application is limited by several...

Ab-Initio Study of Glycerol Dehydration Mechanisms with Explicit Solvent Treatment

Oct 18, 2011
Tim Courtney
Glycerol produced as a waste product in biodiesel production has interesting potential as a low-cost biomass-derived feedstock for chemical processing. A process of current academic and commercial interest is the acid-catalyzed dehydration of glycerol to acrolein, a valuable platform chemical. Such...
