QSJ-01 organic sulfur hydrolyzer is an organic sulfur conversion catalyst made of active H2O3 as carrier and alkali metal as active component. It is suitable for use in industrial devices that use coal as raw material to produce ammonia synthesis gas, methanol synthesis gas, city gas, coal-to-oil or coal-to-olefins. It can convert organic sulfides such as COS and CS2 in process gas into easily removable inorganic sulfides so that they can be completely removed in subsequent stages.
