Enhanced catalyst stability for cyclic co methanation operations

Patent · Sat Jan 01 00:00:00 EST 1983

OSTI ID:864467

Risch, Alan P.; Rabo, Jule A.

Carbon monoxide-containing gas streams are passed over a catalyst to deposit a surface layer of active surface carbon thereon essentially without the formation of inactive coke. The active carbon is thereafter reacted with steam or hydrogen to form methane. Enhanced catalyst stability for long term, cyclic operation is obtained by the incorporation of an alkali or alkaline earth dopant in a silica binding agent added to the catalyst-support additive composition.
