Coal-to-Natural Gas Catalyst Fully Localized for the First Time

Recently, Southwest Chemical Research and Design Institute Co.
, Ltd.
revealed that it and Kingho Energy Group Co.
, Ltd.
formally signed a contract for the supply of CNGC-2 gas conditioner and CNJ-8 methanation catalyst for the 1.
5 billion cubic meters/year coal-to-natural gas project
.
The successful signing of this contract marks the first time that coal-to-natural gas catalysts have been fully localized
.

In recent years, with the sharp increase of people's demand for clean energy natural gas, combined with China's energy characteristics of "rich coal, lack of oil, and little gas", the development of coal-based natural gas has become an effective supplement to China's natural gas resources
.
By making full use of low-quality coal and constructing coal-to-natural gas projects on site, the problem of long-distance transportation of low-quality coal can be solved, and the efficient and clean utilization of coal can also be promoted locally
.

At present, the four coal-to-natural gas projects completed and put into operation in China all adopt the technology of foreign companies.
The process of localization of catalysts for coal-to-natural gas projects is slow, which has become a technical difficulty of coal-to-natural gas
.
In 2010, the Southwest Research Institute initiated a project to conduct research on coal-to-natural gas technology packages and key catalysts; in 2021, the research project was successfully started on the industrial sideline of Kingho Group Coal-to-Gas Company
.
After twelve years, China's coal-to-gas technology and catalyst localization have made major breakthroughs, breaking foreign monopoly
.

According to the relevant person in charge, compared with foreign catalysts, the CNGC-2 gas regulator of the Southwest Institute has higher conversion activity and better stability; CNJ-8 methanation catalyst improves the conversion efficiency of the single-pass methanation reaction and can be applied to more Low hydrogen-to-carbon atomic ratio (H/C) and steam-to-gas ratio are new catalysts that are more energy-efficient, more efficient and more adaptable
.

At the Sichuan Science and Technology Work Conference in 2022, the Sichuan PSA Gas Separation and Purification Engineering Technology Research Center, jointly established by the Southwest Chemical Research and Design Institute and other units, was rated as an advanced platform for scientific and technological innovation in Sichuan
.
Taking industrial exhaust gas and industrial gas as the main research object, the research center has actively carried out the development and engineering of separation, purification and comprehensive utilization technologies for the purpose of improving gas separation efficiency and realizing resource recycling and utilization.
Research and contribute to carbon neutralization
