ENHANCED CATALYST STABILITY FOR CYCLIC CO METHANATION OPERATIONS

摘要

13072ENHANCED CATALYST STABILITYFOR CYCLIC CO METHANATION OPERATIONSAbstract of the DisclosureCarbon monoxide-containing gas streams arepassed over a catalyst to deposit a surface layer ofactive surface carbon thereon essentially without theformation of inactive coke. The active carbon isthereafter reacted with steam or hydrogen to formmethane. Enhanced catalyst stability for long term,cyclic operation is obtained by the incorporation of analkali or alkaline earth dopant in a silica bindingagent added to the catalyst-support additive composition.S P E C I F I C A T I O N-1-
