Olefin production by cracking hydrocarbon feed comprises establishing target carbon monoxide concentration in cracked gas by catalytically decomposing methanol in convection zone

摘要

Olefin production by cracking a hydrocarbon feed in a furnace with a convection zone comprises establishing a target carbon monoxide concentration in the cracked gas by catalytically decomposing methanol in the convection zone to form hydrogen and carbon monoxide. An independent claim is also included for apparatus for olefin production by cracking a hydrocarbon feed, comprising a cracking furnace with a convection zone, a catalyst integrated into the convection zone to decompose methanol into a synthesis gas comprising hydrogen and carbon monoxide, and downstream equipment for processing the cracked gas.
