Catalytic wall reactors and use of catalytic wall reactors for methane coupling and hyxdrocarbon cracking reactions

摘要

Apparatus is described for simultaneous coupling of methane and dehydrogenation of hydrocarbons, or cracking of hydrocarbons. The apparatus contains reaction channels for the methane coupling in or adjacent to channels for the dehydrogenation or cracking reaction. In use, heat evolved by the methane coupling is absorbed by the dehydrogenation or cracking reaction. A dual-flow chemical reactor core is described containing catalytic heat-transfer walls comprising a gas-impervious material and a coupling catalyst and reactors for simultaneous coupling of methane and dehydrogenation of hydrocarbons or cracking of hydrocarbons in separate gas streams and also chemical processes which combine coupling of methane and cracking of hydrocarbons to make olefins in such apparatus.
