Uses for acetic acid span a multitude of industries; from its use as a chemical precursor, to its use as a solvent, and its use as an acidifier. Because sulfur and sulfur compounds will deactivate the catalysts used in the ammonia production process, hydrogenation and/or hydrolysis is used to convert these compounds into H2S to form a sulfur free feedstock. Merichem’s LO CAT® technology is currently part of a major acetic acid production facility in China.
