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...

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...

Research On Enzyme-Catalyzed Sequential Reduction of Carbon Dioxide

Oct 18, 2011

Wenfang Liu

Enzyme-catalyzed reduction of CO2 will not only help to lessen greenhouse effect, but also to obtain valuable chemicals. The sequential reduction of CO2 to methanol under mild reaction conditions has been reported to be feasible by using sol-gel encapsulated or nanoparticle-attached dehydragenases...

Co-Utilization of Methane In Steam-Biomass Gasification Using Concentrated Solar Energy

Oct 18, 2011

Aaron W. Palumbo

Presented is a novel gasification application where biomass is steam-gasified and natural gas is steam-reformed simultaneously in a solar reactor. Solar-driven gasification is a proven technology, and can augment the biofuel industry as a domestic fuel source. Gasification performed in an...

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...

A Model-Assisted Tool for the Characterization of Char In Biomass Pyrolysis and Biomass Catalytic Pyrolysis

Oct 18, 2011

Shoucheng Du

Coke formation appears as a reason for catalyst deactivation and results in undesirable product selectivity in biomass pyrolysis. However, there is no effective way to separate coke and char in the majority of current approaches, which prevents studying coke formation and therefore the real reason...
