The company has developed alumina-type catalysts for sulfur recovery, load-type low-temperature catalysts for sulfur recovery, hydrogenation catalysts for treating tail gas for sulfur recovery, and organic sulfur hydrolysis catalysts for sulfur recovery. It masters the technologies of titanyl sulfur recovery catalysts, hydrogen sulfide selective oxidation catalysts for sulfur recovery, and low-temperature hydrogenation catalysts for treating tail gas from sulfur recovery, etc. It always gets ahead in China in the field of gas purification with CT sulfur recovery and tail gas treatment catalyst series. Its market shares always rank first in China.
It is the first domestic company to carry out the researches on MDEA desulphurization and decarburization technology and desulphurization and decarburization technology with physical-and-chemical solutions, and to realize industrial application. Iron-redox desulphurization technology has been developed and filled the domestic gap.
It has developed natural gas solid desulphurization technology and matched CT solid desulphurization activator series, thus solving the purification problems in remote and scattered low-sour gas well.
