Magnesium nickel silicate (MNS) has been investigated as a catalyst to convert tars and light hydrocarbons to syngas (CO and H2) by steam reforming and CO2 reforming in the presence of H2S for biomass gasification process at NexTech Materials. It was observed that complete CH4 conversion could be achieved on MNS catalyst granules at 800–900 °C and a space velocity of 24,000 mL/g/h in a simulate...

Combustion of conventional energy sources produces pollutants such as SOx, NOx, and CO; the use hydrogen methane can eliminate these harmful emissions. In fuel cell technology other uses, must be refined by extracting from methane/hydrogen combination, produced via dry or steam reforming. This study investigates adsorption separation capabilities recently discovered zeolite-templated carbons (Z...

A new multicylinder microchamber reactor is designed on autothermal reforming of methane for hydrogen production, and its performance and thermal behavior, that is, based on the reaction mechanism, is numerically investigated by varying the cylinder radius, cylinder spacing, and cylinder layout. The results show that larger cylinder radius can promote reforming reaction; the mass fraction of me...

hydrogen was produced by steam reforming of dimethyl ether (dme) using a physical mixture of commercial hzsm-5 zeolite (for dme hydrolyzing) and cu/zno/al2o3 (for methanol steam reforming) as a catalyst in a fixed bed reactor. the experiments were performed at atmospheric pressure and in a temperature range from 270 to 310 °c. the effects of feed temperature and gas hourly space velocity (ghsv)...
