A Catalyst For The Synthesis Of Methane From Carbon Monoxide And Hydrogen And A Method For Catalyst Preparation
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.%):
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 250-300°C and 1-60 atm for 5-7 hr.
