Catalyst for hydrolysis of carbonyl sulfide and hydrogen cyanide and use of titanium dioxide-based composition

A catalyst for hydrolysis of carbonyl sulfide and hydrogen cyanide, comprising at least:

• an active component containing, as a main component, at least one metal selected from the group consisting of barium, nickel, ruthenium, cobalt, and molybdenum;
• and
• a titanium dioxide-based support supporting the active component, wherein
• the support comprises at least one titanium dioxide-based composite oxide selected from the group consisting of composite oxides of titanium dioxide and silicon dioxide, composite oxides of titanium dioxide and aluminum oxide, and composite oxides of titanium dioxide and zirconium dioxide.
