Abstract

The invention discloses a composition for carbon catalytic hydrogenation to methane. The composition comprises: cobalt salt, iron salt and calcium salt, wherein the mass ratio of Co:Fe:Ca is 0.25-1.5: 0.25~1.5:1.5. Compared with the existing catalysts for catalytic hydrogenation of coal to methane, the composition of the present invention adopts a Co-Fe-Ca ternary combination, which not only has a good catalytic effect, but also has the advantages of good stability, low deactivation and low cost , suitable for industrial use.

Description

technical field [0001] The invention belongs to the field of catalytic hydrogenation, in particular to a composition for catalytic hydrogenation of carbon to methane, and the application of the composition in catalytic hydrogenation of solid carbonaceous materials to prepare methane. Background technique [0002] my country's overall energy characteristics are "more coal, less oil, less gas". With the development of my country's economy and the strengthening of environmental protection, the demand for natural gas is rising rapidly. It is suitable to convert the abundant coal into natural gas through catalytic gasification. The choice of my country's national conditions and development strategy is also an inevitable trend for efficient integration of resources and improvement of coal resource utilization. [0003] According to the different chemical reaction steps, coal-to-natural gas technology can be divided into direct coal-to-natural gas technology and indirect coal-to-nat...
