Preparation of catalysts for methanethiol synthesis

Claim 1

THE METHOD OF PREPARING A CATLYST CONSISTING OF AN ACTIVE COMPONENT COMPRISING THE OXIDES OF METALS SELECTED FROM THE GROUP CONSISTING OF THORIUM, ZIRCONIUM, TITANIUM, URANIUM, TUNGSTEN, MOLYDBENUM AND CHROMIUM SUPPORTED ON A DRY POROUS CARRIER MATERIAL WHICH COMPRISES DISSOLVING A HEAT-DECOMPOSABLE COMPOUND OF SAID ACTIVE COMPNENT IN A MONOCHYDRIC ALIPHATIC ALCHOL HAVING UP TO 6 CARBON ATOMS TO THE MOLECULE AND A SURFACE TENSION OF NOT MORE THAN 30 DYNES PER CENTIMETER, IMPREGENATING SAID DRY CARRIER WITH SAID ALCHOL SOLUTION AT A TEMPERATURE OF ABOUT 10* TO 30*F BELOW THE BOILING POINT OF THE ALCOHOL WHEREBY THE SURFACE TENSION OF THE IMPREGNATING SOLUTION IS NOT MORE THAN 30 DYNES PER CENTIMETER AT THE IMPREGNATING TEMPERATURE, HEATING SAID IMPREGNATED CARRIER TO EVAPORATE SAID ALCHOL THERFROM AND CALCINING SAID THUS DRIED CARRIER MATERIAL TO CONVERT THE HEAT-DE COMPOSABLE COMPOUND TO THE CORRESPONDING METAL OXIDE.

Claim 2

THE METHOD OF PREPARING A CATLYST CONSISTING OF AN ACTIVE COMPONENT COMPRISING THE OXIDES OF METALS SELECTED FROM THE GROUP CONSISTING OF THORIUM, ZIRCONIUM, TITANIUM, URANIUM, TUNGSTEN, MOLYDBENUM AND CHROMIUM SUPPORTED ON A DRY POROUS CARRIER MATERIAL WHICH COMPRISES DISSOLVING A HEAT-DECOMPOSABLE COMPOUND OF SAID ACTIVE COMPNENT IN A MONOCHYDRIC ALIPHATIC ALCHOL HAVING UP TO 6 CARBON ATOMS TO THE MOLECULE AND A SURFACE TENSION OF NOT MORE THAN 30 DYNES PER CENTIMETER, IMPREGENATING SAID DRY CARRIER WITH SAID ALCHOL SOLUTION AT A TEMPERATURE OF ABOUT 10* TO 30*F BELOW THE BOILING POINT OF THE ALCOHOL WHEREBY THE SURFACE TENSION OF THE IMPREGNATING SOLUTION IS NOT MORE THAN 30 DYNES PER CENTIMETER AT THE IMPREGNATING TEMPERATURE, HEATING SAID IMPREGNATED CARRIER TO EVAPORATE SAID ALCHOL THERFROM AND CALCINING SAID THUS DRIED CARRIER MATERIAL TO CONVERT THE HEAT-DE COMPOSABLE COMPOUND TO THE CORRESPONDING METAL OXIDE.
