In a process for steam reforming of oxygenates, especially at low steam-to-carbon (S/C) ratios, a feed gas containing oxygenates, such as ethanol, is converted into syngas over a ternary carbide catalyst. Then the reformed gas is either transformed into desired chemicals or mixed into the feed stream to the reformer in a plant, such as an ammonia or methanol plant. The preferred ternary carbide is nickel zinc carbide.

Process for steam reforming of oxygenates and catalysts for use in the process

A catalyst for the dehydrogenation of alkanes to alkenes comprises a catalytically active material supported on a carrier, wherein the catalytically active material is a metallic sulfide (MeS) comprising Fe, Co, Ni, Cu, Mo or W or any combination of two or more metals selected from Pb, Sn, Zn, Fe, Co, Ni, Cu, Mo and W. The catalyst is regenerated in several steps. The dehydrogenation is carried out at a temperature between 450 and 650&#xb0; C. and a pressure from 0.9 bar below ambient pressure to 5 bar above ambient pressure.

Sulfide-based alkane dehydrogenation catalysts

NH&#x2014;SCR catalyst, containing iron promoted beta-zeolite, cerium oxide and titanium oxide and optionally further containing at least one of tungsten oxide, neodymium oxide, silicon oxide and diatomaceous earth, and method of preparation thereof.
