CARBONYL SULFIDE PRODUCTION METHOD

Title:

CARBONYL SULFIDE PRODUCTION METHOD

Document Type and Number:

WIPO Patent Application WO/2024/070744

Kind Code:

A1

Abstract:

Provided is a carbonyl sulfide production method that can produce carbonyl sulfide with a good yield using a gas-phase flow method and without using a catalyst. This method for producing carbonyl sulfide comprises: a step for exciting, in hot plasma, a crude gas comprising a starting substance containing carbon atoms, sulfur atoms, and oxygen atoms; and a step for cooling the crude gas excited by plasma.
