Abstract

The hydrolysis of carbonyl sulfide is substantially improved by utilizing titanium dioxide particles as a catalyst. It is especially favorable, if the titanium dioxide particle are sintered and treated with sodium hydroxide or sodium aluminate. Through such a treatment, the catalyst can be regenerated and reutilized.
