Material and Engineering Assessments of Electrochemical Processes for Carbon Capture Technology

Oct 18, 2011

Fritz Simeon

Integrating carbon capture technology with large source carbon emitters is necessary in the very near future to mitigate the contribution of anthropogenic CO 2 emissions to climate change and global public welfare. However, the implementation of this technology with current separation approaches is...

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...

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...

The Capture of Carbon Dioxide by Ionic Liquid

Oct 18, 2011

Hongyan He

Ionic liquid is one kind of organic salts with negligible volatile pressure which might lead to promising substitute candidates for alkanolamines in separation of carbon dioxide. To satisfy this requirement effectively, task specific ionic liquids with alkaline groups, such as imidazolium cation...

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...

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...

Study of Culture Strategies of Microalgae In a Continuous Photobioreactor System for Biofuel Production

Oct 18, 2011

Haiying Tang

The development of new biomass sources for alternative fuels has become a subject of increasing importance as the nation strives to resolve the economic and strategic impacts of limited fossil fuel resources on our national security, environment, and global climate. Algae are among the most...

Study on the Pyrolysis Characteristics of Biomass Compositions in Medical Wastes DENG Na * , Wang Weiwei, ZHANG Yu-feng, MA Hong-ting （School of Environmental Science & Engineering, Tianjin Uninversity, Tianjin 300072, China) Abstract: To obtain pyrolysis characteristics of biomass compositions...

Phase-Changing Absorbents for CO2 Capture

Oct 18, 2011

Sarah Genovese

A process to capture CO 2 from flue gas using a liquid material that reacts rapidly with CO 2 to form a solid offers many advantages over conventional liquid-only CO 2 capture methods. The net CO 2 capacity of the system will be increased, the overall system size will be decreased, and the energy...

Biomimicry of the Fungal Consolidation of Biomass Pretreatment with Saccharification

Oct 18, 2011

Justin T. Kaffenberger

Efficient breakdown of ligno-cellulosic material prior to fermentation for bio-fuel production is a key step in optimizing bio-fuel production. Current industrial practice involves chemical pretreatment and acid or enzymatic saccharification to prepare ligno-cellulosic biomass for fermentation. The...

Conversion of Cellobiose Into Glucose At near-Neutral pH Using a Recyclable Heterogeneous Catalyst

Oct 18, 2011

Po-Wen Chung

Strong acids under severe reaction conditions are known to rapidly hydrolyze cellulose with moderate selectivity towards glucose; however, enzymes in nature convert saccharides into glucose at higher selectivity using mild conditions dictated by carboxylate acids/carboxylate bases at the active...

Comparison of Amine-Based Absorbents for Post-Combustion Carbon Capture

Oct 18, 2011

Sumedh S. Warudkar

As a part of this work, we have performed a comparison of 4 amine-based absorbents using the process simulation software ProMax ® with TSWEET ® . Absorbents were compared at pulverized coal fired power plant flue gas conditions. The criteria for comparison of absorbents are the energy requirement...

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...

A New Metal-Decorated Carbon Catalyst for Dehydrogenation of Complex Hydride Hydrogen Storage Materials

Oct 18, 2011

Sean S.-Y. Lin

In recent years, many new solid-state hydrides with a high hydrogen capacity that meet DOE requirement (> 7.5 wt.% H 2 ) have been synthesized as promising on-board hydrogen storage materials. In these hydrides, however, only a small fraction of hydrogen can be released at a desired on-board...

Catalytic Isomerization/Dehydration of Sugars On Functionalized CNT-Metal Oxide Hybrids At the Liquid-Liquid Interface of Water/Oil Emulsions

Oct 18, 2011

Jimmy A. Faria

The conversion of C5-C6 sugars into 2-furfural (FA) and 5-hydroxymethylfurfural (HMF) have been considered as key intermediate step in the production of transportation fuels and chemicals from ligno-cellulosic biomass. Typically, the process involves the dehydration reaction of the sugars catalyze...
