Nickel-Based Autothermal Reforming Catalysts: Effect of Particle Size On Sulfur Tolerance

Oct 18, 2011

Johannes W. Schwank

Autothermal reforming (ATR) of liquid hydrocarbon fuels over nickel-based catalysts produces an equilibrium-limited mixture of hydrogen-rich syngas that is suitable as feed for solid oxide fuel cells. Autothermal reforming involves exothermic partial oxidation as well as endothermic steam reforming...

Improving Gas Condensate Reservoir Productivity

Oct 18, 2011

Adel Elsharkawy

Gas condensate reservoirs experience great losses in productivity as the reservoir pressure drops below the dew point pressure due to formation and accumulation of liquid condensate around the well bore and subsequent reduction of gas relative permeability. Several methods have been proposed to...

New Catalytic Technology for Converting Heavy Oils Derived From Alberta Oil Sands Into Petrochemical Feedstock

Oct 18, 2011

Vasily Simanzhenkov

Oil sands operations in Alberta are poised to experience significant growth over the next number of years. Production of 1.31 million bbl/day of synthetic crude oil and bitumen blends from oil sands in 2008 is projected to increase to over 3 million bbl/day by 2018. This guarantees a large output...

Simultaneously Increasing Profit and Reducing Emissions Through Process Optimization for Integrated Petrochemical Plants

Oct 18, 2011

Jian Zhang

Refineries and petrochemical plants are leading segment of the entire chemical process industry. It was reported that the value of the product shipments by refineries in U.S. accounted for 9.32% of the entire manufacturing sector of the U.S. economy in 2007. On the other hand, air emissions from...

Accelerated Thermal Decomposition of Ammonia Borane by Carbon Dioxide

Oct 18, 2011

Junshe Zhang

This talk presents the enhanced dehydrogenation of ammonia borane (AB) at 85 o C under CO2, an abundant and naturally occurring material. The presence of CO 2 significantly accelerates the thermal decomposition and it kinetics becomes faster as the CO 2 pressure increases from 1.70 to 3.67 bar...

Development of a Compact Fischer Tropsch Reactor

Oct 18, 2011

Lyman Frost

Fischer Tropsch (FT) synthesis is a polymerization process where a CH X species is added to a growing aliphatic chain. There are several models of the catalytic chain propagation rate and the termination of the chain growth (e.g. Anderson – Schulz – Flory model). The exact methodology for the...

Assessment of Filter Conditioning During Cross-Flow Filtration of Simulated Tank Waste

Oct 18, 2011

Philip P. Schonewill

Crossflow filtration is to be a key process in the treatment and disposal of approximately 60,000 metric tons of high-level waste stored at the Hanford Site in Richland, Washington. Pacific Northwest National Laboratory (PNNL) is assessing filter performance against waste simulant materials that...

Thermodynamics Studies of Metal Oxides Conversion for CO2 Sequestration In Steel Industry

Oct 18, 2011

Hui Li

Due to the concerns of “global warming”, CO2 sequestration from steel industry are becoming more and more important for the environments FeCO3, one of component for steel, was selected to investigate in order to design suitable processing to sequestrate the CO2 at the steel plant. It was found that...

Preparation and Testing of Adsorbents for the Separation of Ionic Liquids From HMF

Oct 18, 2011

Yuxiang Rao

HMF is an important chemical product since it has the potential to be used as a feedstock to replace petroleum-derived aromatics for production of a range of specialty chemicals and plastics.In this work, we will demonstrate an economically-viable, ionic liquid catalytic process for conversion of...

Gas Fermentation of Industrial Waste Gases to Fuel and Chemicals

Oct 18, 2011

Derek W. Griffin

The food versus fuel debate is becoming increasingly controversial in the wake of the industrialization of eastern countries and the ever-growing population of the world. Sustainable and renewable feed stocks are being explored as energy sources in order to meet the increasing energy demand and...

Activated Carbon Process for Simultaneous SOx/NOx Removal From Concentrated CO2 At Elevated Pressures

Oct 18, 2011

Monica Zanfir

Background Oxy-combustion is considered as one of the CO 2 capture options for the coal-fired power plants. The CO 2 -rich flue gas from such a plant will have to be compressed and purified for sequestrtion. Praxair is developing a near zero emissions technology that will produce CO 2 virtually...
