Modeling of Asphaltene Deposition In a Vertical Tubing

Oct 19, 2011

Dmitry Eskin

Asphaltene deposition phenomena are investigated both theoretically and experimentally. A Couette device, where the inner cylinder rotates and particles deposit on the outer wall, is used for laboratory studies of the deposition process. The modeling approach, recently proposed by the authors (...

A Novel Reactive Distillation Approach for Producing 1,3-Dihydroxyacetone From Glycerol

Oct 19, 2011

Dennis J. Miller

Glycerol is a viable renewable feedstock that has emerged as a consequence of triglyceride conversion to biodiesel. In addition to glycerol conversion to commodity chemicals such as propylene glycol and epichlorohydrin, formation of higher-value specialty chemical products such as 1,3-...

Effects of Ammonia Substitution On Stability Limits and Emissions of Premixed Hydrogen/Air Flames

Oct 19, 2011

Dong Hyun Um

The potential of partial ammonia (NH 3 ) substitution to improve the safety of hydrogen (H 2 ) use was evaluated, using premixed NH 3 /H 2 /air flames at normal temperature and pressure generated on a tube type burner. The effects of NH 3 substitution on the stability limits and nitrogen oxide (NO...

Evaluation of Organic Rankine Cycle Geothermal Power Plant and Considerations

Oct 19, 2011

Kirtipal Barse

The objective of this work is to evaluate the feasibility of an Organic Rankine Cycle (ORC) power plant to generate electricity from low flow rates of a geothermal resource (~875 gpm) at low temperatures (T~100°C). A model of ORC was developed using HYSYS process simulator. DOE’s Cost of Renewable...

Physical Properties and Rheological Characteristics of Deasphalted Oil Produced From a Solvent Deasphalting Process

Oct 19, 2011

Jung Moo Lee

Because of conventional oil being-exhausted and its increasing price, the technologies to use unconventional oil and low value crude residues, which have not been fully exploited, are receiving more and more interest. Unconventional oil contains a lot of asphaltene which hinders utilizability of...

Lifetime and Efficiency Studies of Zinc/Bromine Electrochemical Energy Storage In Large Scale Renewable Energy Applications

Oct 19, 2011

Alex Bistrika

As the world's power needs grow, the demand for power from renewable resources, such as wind or solar, is increasing. One major drawback associated with these renewable resources is that the power output is dependent on environmental factors, such as cloud cover and wind speeds. This allows 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...

Hose: PRESSURE-Assisted Extraction of Bitumen FROM OIL SANDS for High YIELD and Environmetally Acceptable BYPRODUCTS

Oct 18, 2011

Xinyue Zhao

Hot water extraction of bitumen from oil sands has been commercially applied for decades. The extraction process is greatly aided by the addition of caustics and other reagents, which adversely impact handling and disposal of byproducts at process end. Recent effort of increasing energy efficiency...

A New Generation of Zirconia Supported Metal Oxide Catalysts for Esterification of Free Acid Feedstocks

Oct 18, 2011

Manhoe Kim

The acid catalyst promotes esterification by reacting the carboxylic group of the FFA with methanol to form methylesters and water. In this reaction mixture, the sulfuric acid is more miscible in the water product phase than the methanol phase leading to a pronounced water inhibition effect that...

Production of Synthetic Paraffin Kerosene by Hydrocracking Fischer-Tropsch Wax

Oct 18, 2011

H. Nicholas Conkle

The US Air Force has committed to an alternative aviation-fuel initiative to implement a roadmap for testing and certifying alternative fuel components including biomass-derived alternatives produced from non-food plants, animal fats, and algae, as well as synthetic fuel components derived from...

Pilot Test for Fischer-Tropsch Synthesis Using a Fixed Bed Compact Heat Exchange Reactor

Oct 18, 2011

Hani Gadalla

Abstract A fixed-bed compact heat exchange reactor (CHER) was designed and constructed for by Chart Fischer-Tropsch (FT) reaction. This reactor contained a plate-fin structure with layers of mini-channels (channels having ~5 mm equivalent diameter) containing a total of 80 g of cobalt based...
