Mechanistic investigation of methane steam reforming over Ce-promoted Ni/SBA-15 catalyst

Application of a combined catalyst and sorbent for steam reforming of methane

The performance of a combined catalyst and sorbent material designed for reforming hydrocarbons was evaluated by reacting methane with steam at different temperatures and pressures in a reactor packed with the material. The combined material was in the form of small spherical pellets comprised of a sorbent core of lime encased in a porous shell made largely of sintered alumina that supported a ...

Electrodeposited Re-promoted Ni foams as a catalyst for the dry reforming of methane

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...

Mechanistic Kinetic Models for Steam Reforming of Concentrated Crude Ethanol on Ni/al2o3 Catalyst

Mechanistic kinetic models were postulated for the catalytic steam reforming of concentrated crude ethanol on a Ni-based commercial catalyst at atmosphere pressure in the temperature range of 673-863 K, and at different catalyst weight to the crude ethanol molar flow rate ratio (in the range 0.9645-9.6451 kg catalyst h/kg mole crude ethanol) in a stainless steel packed bed tubular microreactor....

Investigation of Inert Gas Injection in Steam Reforming of Methane: Energy

Synthesis gas manufacturing by steam reforming of hydrocarbons is an important industrial process. High endothermic nature of the process makes it one of the most cost and heat intensive processes. In the present work, composite effect of different inert gases on synthesis gas yield, feed gas conversion and temperature distribution along the reactor length has been studied using a heterogeneous...
