Article history: Received 11 October 2015 Received in revised form 2 December 2015 Accepted 15 December 2015 Available online 17 December 2015 The dry reforming of methane (DRM) utilizes carbon dioxide (CO2) as the oxidizing agent in order to produce synthesis gas. Catalyst deactivation via coking, oxidation, and sintering has stymied the industrialization of catalysts for the DRM. Here, we uti...

A methane Raman cell optimized for generating high energy laser pulses at 1.54 microns wavelength is characterized. 1st Stokes conversion efficiencies up to 43% – equivalent to 62% photon conversion efficiency – were measured. Experimental results show output average power in excess of 17.5 W, pulse energies of 350 mJ at 50Hz, with good beam quality (M < 6.) Narrow bandwidth output is produced ...

The selective oxidation of methane to methanol is a key challenge in catalysis. Iron and copper modified ZSM-5 catalysts are shown to be effective for this reaction using H2O2 as the oxidant under continuous flow operation. Co-impregnation of ZSM-5 with Fe and Cu by chemical vapour impregnation yielded catalysts that showed high selectivity to methanol (> 92% selectivity, 0.5 % conversion), as ...

General modeling and optimization of syngas production via noncatalytic autothermal partial oxidation of methane are carried out using our developed scientific software which was based on the minimization of total Gibbs energy. In this work, a novel application of the direct search and Newton-Raphson methods was introduced to apply to optimization of a complex chemical reaction. Sensitivity ana...

Cobalt chromite (CoCr2O4) with normal spinel structure, shows catalytic activity for oxidation of unburned methane in the natural gas vehilcles (NGV). In this study, CoCr2O4 nanoparticles were synthesized through a conventional co-precipitation technique and investigated for the catalytic combustion of methane. Cobalt nitrate hexahydrate,...
