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...

The Effects of Carbon-to-Oxygen ratio upon Supercritical Water Reformation for Hydrogen Production Jared Bouquet 1 , Ryan Tschannen 2 , Aaron Gonzales 2 , and Sunggyu Lee 2 1: Missouri University of Science and Technology, Rolla, MO 2: Ohio University, Athens, OH With the continually growing energy...

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...

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...

In recent years, a large number of studies (feasibility, computational and real time analyses) have been performed on water gas shift (WGS) reaction in membrane reactors. The WGS reaction in a membrane reactor (MR) is potentially capable of completing the CO conversion and achieving simultaneous H...

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...

This study reports the development of a Ni based oxygen carrier and the investigation of an Integrated Gasification (IG) and Combustion of solid biomass as a fuel for Chemical-Looping Combustion (CLC). The aim is to develop a highly reactive, stable and fluidizable oxygen carrier (OC): a cobalt (Co...

The University of Kentucky, Center for Applied Energy Research is investigating oxygen carriers (OC) for chemical looping combustion (CLC) with the goal of developing a pressurized chemical looping combustion/gasification process for generating electricity from coal. An important issue in the...

Ammonia Borane (AB), with high hydrogen storage capacity (19.5 wt.%), is predicted to be possibly a future fuel for providing pure H 2 to fuel cell at room temperature for on-board and portable applications. However, a heterogeneous catalyst plays a vital role for first initiating and then...
