Abstract

The invention provides a method for producing natural gas through methanation of synthesis gas. The method comprises the step of carrying out contact reaction by virtue of the synthesis gas and a catalyst. The method is characterized in that the catalyst comprises continuous phase carbon and disperse phase Raney alloy, wherein the continuous phase carbon is obtained by carbonizing one or more carbonizable organic matters. When the natural gas is produced through the methanation of the synthesis gas, the conversion rate of carbon oxide in the synthesis gas is relatively high, and furthermore, the conversion rate of carbon oxide can still reach 97% or above at a relatively high air speed.

Description

technical field [0001] The invention relates to the field of producing natural gas by methanation of synthesis gas, more specifically a method for producing natural gas by methanation of synthesis gas using a Raney alloy catalyst. Background technique [0002] Among the major energy consuming countries, the proportion of coal in my country's total energy consumption is the highest, reaching 66% in 2013, and this figure was 71.1% in 2007, falling for 6 consecutive years, which is still three times the global average level, while the proportion of natural gas is the lowest , accounting for only 5.8% of the total, and its proportion has increased for more than 10 consecutive years, but it is still very inconsistent with the proportion of natural gas consumption in the world's energy consumption structure of 45%. Since the greenhouse gas produced by natural gas combustion is only 1 / 2 of that of coal and 2 / 3 of that of oil, the degree of damage to the environment is less than that...
