Effects of Reaction Conditions On the Acid-Catalyzed Hydrolysis of Miscanthus Dissolved In An Ionic Liquid

Oct 19, 2011

Sean J. Dee

Miscanthus, a perennial grass, is an attractive biofuel feedstock compared with corn and poplar due to its high energy yield per hectare and low agricultural inputs such as water and soil nutrients. Recent studies have shown the three primary components of miscanthus, cellulose, hemicellulose, and...

Green and High Efficient Enzyme Hydrolysis Process for Sweet Sorghum Bagasse

Oct 19, 2011

Xinshu Zhuang

In order to improve enzymatic hydrolysis efficiency, several approaches including liquid hot water (LHW) pretreatment, adding surfactant, magnetic stirring and fed-batch hydrolysis were investigated, in which Sweet sorghum bagasse (SSB) was chosen as the feedstock. The experiment results showed...

Bioconversion of Brown Seaweed Into Mixed Ketones Through the Carboxylate Platform Processing

Oct 19, 2011

Xin Chen

The Carboxylate Platform, also known as the MixAlco TM process, is an acidogenic fermentation process using mixed culture inoculums, which offers several advantages compared to conventional bioprocessing, such as: non-sterile fermentation, the use of inexpensive tanks, adaptability to a wide...

Biofuels Manufacturing: From Feedstocks to Manufacturing and End-Product Quality Control

Oct 19, 2011

Jose Menezes

Biofuels quality is related to the inherent of feedstock materials (RMs) and operating conditions used in their production. However to be used as fuel in engines biofuels must meet certain specifications regulated by ASTM or EN standards regardless of the manufacturing processes and / or the type...

Philip A. Marrone

Sub- and Supercritical Water Based Processes for Conversion of Algae Biomass to Fuels and Green Chemicals – A Review Philip A. Marrone and Bryan V. Yeh Science Applications International Corporation (SAIC) 60 Wells Ave, Suite 103 Newton, MA 02459 In recent years, there has been increasing...

Isoconversional Methods Applied to Kinetic Modeling Oxidative Alkaline Pretreatment of Sugarcane Bagasse

Oct 18, 2011

Rocio Sierra

Delignification (decrease of lignin content) has shown to be a valid method to significantly increase lignocellulosic feedstocks digestibility. This operation (widely known as pretreatment) makes these abundantly available and inexpensive feedstocks usable in fermentation processes whose main goal...

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...

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...

Triacylglycerol Production From Corn Stover Silage Using a Xylose-Fermenting Rhodococcus Opacus Strain

Oct 18, 2011

Kazuhiko Kurosawa

Background: Biodiesel, monoalkyl esters of long-chain fatty acids attached to short-chain alcohols derived from triacylglycerols (TAGs), can be produced from renewable biomass sources. There has been interest in producing TAGs from oleaginous microorganisms. As published recently (J Biotechnol...
