SYNTHESIS METHOD OF CARBONYL SULFIDE AND APPARATUS THEREFOR

WIPO Patent Application WO/2024/101848

A1

The present invention relates to a method and an apparatus for synthesizing carbonyl sulfide and, more specifically, to: a method for synthesizing carbonyl sulfide, comprising the steps of obtaining a mixed gas containing carbonyl sulfide by contacting at least one form of sulfur from among a liquid phase and a gas phase with carbon monoxide (CO), and further converting unreacted sulfur and carbon monoxide into carbonyl sulfide by contacting the mixed gas with a sulfurization catalyst, wherein the sulfurization catalyst comprises molybdenum (Mo) as the main active metal; and an apparatus for synthesizing carbonyl sulfide, comprising a gas-liquid reactor that obtains a mixed gas containing carbonyl sulfide by contacting carbon monoxide (CO) with at least one form of sulfur from among a liquid phase and a gas phase, and a catalytic reactor that further converts unreacted sulfur and carbon monoxide into carbonyl sulfide by contacting the mixed gas with a sulfurization catalyst, wherein the catalytic reactor comprises a sulfurization catalyst including molybdenum (Mo) as the main active metal.
