Title:
CATALYST FOR PRODUCING HIGH-CALORIE SYNTHETIC NATURAL GAS AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2018/151568
Kind Code:
A1
Abstract:
In the present invention, a methane- and C2-C4 paraffin-containing synthetic natural gas is prepared from carbon monoxide in the presence of a Ni- and Fe-containing catalyst, which contains, on the basis of 100 parts by weight of iron and nickel as active metals, 80-95 parts by weight and 5-20 parts by weight of iron and nickel, respectively, and contains a spinel structure of magnetite. The catalyst according to the present invention, which is a catalyst using two or more kinds of active metals to induce simultaneous occurrence of an FT synthesis reaction and a methanation reaction, can produce a synthetic natural gas, which is mainly configured of methane from hydrogen and carbon monoxide and has a high content of C2-C4 paraffin and a high calorific value of 9,000-13,000 Kcal/Nm3, and can simplify the process compared with an existing natural gas synthesis process due to high productivity of C1-C4.
