Abstract

This invention relates to catalysts for the synthesis of hydrocarbons from carbon monoxide and hydrogen, in particular, to catalysts for methane synthesis. The catalyst comprises cobalt and cerium-containing component. Cobalt of cubic modification is used in order to improve the catalyst activity and selectivity. The catalyst contains cerium dioxide and cerium hydride as the cerium-containing components, and carbon and has the following composition (wt.%):

Cobalt 31.4-88.8
Cerium Dioxide 10.5-68.4
Cerium hydride 0.1-0.2
Carbon the rest

To improve the activity and selectivity characteristics, the catalyst is pretreated in a mixture of carbon monoxide and hydrogen (CO:H2=1:(2-3)) at 250-300C and 1-60 atm for 5-7 hr.
