The Effects of Solvent On Glucose Conversion to 5-Hydroxymethylfurfural

Nov 2, 2012
Xianghong Qian
Cellulosic biomass represents an abundant renewable resource for the production of bio-based products and biofuels. 5-hydroxymethylfurfural (HMF) is a critical and versatile intermediate for converting biomass to liquid alkanes and many other value-added products. However, cost effective conversion...

Upgrading of Biomass-Derived Liquid to Clean Fuels

Nov 2, 2012
Siauw H. Ng
The objective of this study is to develop and demonstrate a viable economical pathway to produce renewable transportation fuels from cellulosic biomass such as wood chips, forest wastes, and agriculture residues.

Evaluation of Mercury Capture Technology Using Various Sorbents Injection

Nov 2, 2012
Xiaofei Wang
Coal combustion is a single largest known anthropogenic source for mercury (Hg) emission. Recently, US EPA has proposed Mercury and Air Toxics Standards (MATS) in order to regulate emissions of Hg and other pollutants. Many Hg control technologies have been developed, such as activated carbon...

Aqueous Morpholine As a Potential Post-Combustion CO2 Absorption Solution

Nov 1, 2012
Krishna Mohan Jinka
Due primarily to high cyclic capacity and high absorption rates compared to other methods, aqueous amine based CO 2 capture has gained great interest for application to post-combustion CO 2 capture. While aqueous amines have a long history for acid gas removal, challenges remain for the commercial...

Enhancement in Enzymatic Hydrolysis by Mechanical Refining of Pretreated Biomass

Nov 1, 2012
Brandon W. Jones
Cellulose is the most abundant natural polymer. Therefore, cellulosic bioethanol has been identified as a fuel source that has tremendous potential to supplement the United States consumption of non-renewable transportation fuel sources. Although cellulosic bioethanol is poised for market entry,...

Mass Transfer Evaluation of CO2 Absorption in a Wetted Wall Column

Nov 1, 2012
Reynolds A. Frimpong
The chemical absorption of CO 2 in solvents is considered as one of the mature process options for reducing CO 2 emissions in power plants. Solvents with fast mass transfer rates and high CO 2 carrying capacity are therefore desired and continue to be explored to reduce equipment size and its...

Vinod Srinivasan
Providing nearly 400 enzyme products ranging from food and beverages to household cleaning and biofuels, Genencor has been a world leader in industrial biotechnology and a pioneer in enzyme innovation. Now a part of DuPont, DuPont Industrial Biosciences provides enzyme products for biomass...

Modification of Fracture Hydraulic Properties by CO2-Acidified Brine Flow

Nov 1, 2012
Hang Deng
Geological storage of CO 2 is a promising option for carbon mitigation, but its application faces challenges such as the possibility of CO 2 leakage. Quantification of the leakage risks requires characterization of the porosity and permeability of the porous media, and prediction of dynamic...
