  • PROCESS FOR STEAM REFORMING OF OXYGENATES AND CATALYSTS FOR USE IN THE PROCESS
    Publication number: 20230047360
    Abstract: 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.

  • A PROCESS FOR THE DEHYDROGENATION OF ALKANES TO ALKENES AND IRON-BASED CATALYSTS FOR USE IN THE PROCESS
    Publication number: 20210139394
    Abstract: In a process for the catalytic dehydrogenation of lower alkanes to the corresponding alkenes, a regenerable catalyst comprising iron carbide supported on a carrier is used. A small amount (below 100 ppm) of a sulfur compound, such as H2S, is added during the process.

  • Sulfide-based alkane dehydrogenation catalysts
    Patent number: 10722871
    Abstract: 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° C. and a pressure from 0.9 bar below ambient pressure to 5 bar above ambient pressure.
