Refractory oxide-alkaline earth carbonate supported catalyst

Claim 1

A METHOD FOR PREPARING A CATALYST WHICH COMPRISES IMPREGNATING AN ALKALINE EARTH CARBONATE WITH AN AQUEOUS SOLUTION OF A COMPOUND OF A METAL SELECTED FROM THE GROUP CONSISTING OF THE TRANSITION HEAVY METALS OF THE PERIODIC TABLE, SAID COMPOUND BEING HYDROLYZABLE TO A CATALYTICALLY ACTIVE MATERIAL, HYDROLYZING THE HYDROLYZABLE COMPOUND TO DEPOSIT THE CATALYTICALLY ACTIVE MATERIAL IN THE ALKALINE EARTH CARBONATE, THEN INTIMATELY ADMIXING A REFRACTORY OXIDE SELECTED FROM THE GROUP CONSISTING OF ALUMINA, SILICA, CLAY, ZIRCONIA AND TITANIA WITH THE ALKALINE EARTH CARBONATE THE ALKALINE EARTH CARBONATE AND REFRACTORY OXIDE BEING ADMIXED TOGETHER IN PROPORTIONS, BY WEIGHT, BETWEEN ABOUT 5 PERCENT AND 95 PERCENT OF THE ALKALINE EARTH CARBONATE AND THE BALANCE THE REFRACTORY OXIDE, AND FORMING THE ADMIXTURE WHILE OF PLASTIC CONSISTENCY INTO A BODY OF THE DESIRED SHAPED.

Claim 2

A METHOD FOR PREPARING A CATALYST WHICH COMPRISES IMPREGNATING AN ALKALINE EARTH CARBONATE WITH AN AQUEOUS SOLUTION OF A COMPOUND OF A METAL SELECTED FROM THE GROUP CONSISTING OF THE TRANSITION HEAVY METALS OF THE PERIODIC TABLE, SAID COMPOUND BEING HYDROLYZABLE TO A CATALYTICALLY ACTIVE MATERIAL, HYDROLYZING THE HYDROLYZABLE COMPOUND TO DEPOSIT THE CATALYTICALLY ACTIVE MATERIAL IN THE ALKALINE EARTH CARBONATE, THEN INTIMATELY ADMIXING A REFRACTORY OXIDE SELECTED FROM THE GROUP CONSISTING OF ALUMINA, SILICA, CLAY, ZIRCONIA AND TITANIA WITH THE ALKALINE EARTH CARBONATE THE ALKALINE EARTH CARBONATE AND REFRACTORY OXIDE BEING ADMIXED TOGETHER IN PROPORTIONS, BY WEIGHT, BETWEEN ABOUT 5 PERCENT AND 95 PERCENT OF THE ALKALINE EARTH CARBONATE AND THE BALANCE THE REFRACTORY OXIDE, AND FORMING THE ADMIXTURE WHILE OF PLASTIC CONSISTENCY INTO A BODY OF THE DESIRED SHAPED.

Claim 3

A METHOD FOR PREPARING A CATALYST SUPPORT WHICH COMPRISES INTIMATELY MIXING TOGETHER A REFRACTORY OXIDE SELECTED FROM THE GROUP CONSISTING OF ALUMINA, SI ICA, CLAY, ZIRCONIA AND TITANIA, AN ALKALINE EARTH CARBONATE AND WATER, THE ALKALINE EARTH CARBONATE AND REFRACTORY OXIDE BEING MIXED TOGETHER IN THE PROPORTIONS OF, BY WEIGHT, BETWEEN ABOUT 5 PERCENT AND 95 PERCENT OF THE ALKALINE EARTH CARBONATE AND THE BALANCE THE REFRACTORY OXIDE, FORMING THE MIXTURE WHILE OF PLASTIC CONSISTENCY INTO A CATALYST SUPPORT BODY OF HE DESIRED SHAPE, AND CALCINING THE SHAPED CATALYST SUPPORT BODY AT A TEMPERATURE BELOW THE DECOMPOSITION TEMPERATURE OF THE ALKALINE EARTH CARBONATE TO EXPEL THE WATER THEREFROM.

Claim 4

A METHOD FOR PREPARING A CATALYST SUPPORT WHICH COMPRISES INTIMATELY MIXING TOGETHER A REFRACTORY OXIDE SELECTED FROM THE GROUP CONSISTING OF ALUMINA, SI ICA, CLAY, ZIRCONIA AND TITANIA, AN ALKALINE EARTH CARBONATE AND WATER, THE ALKALINE EARTH CARBONATE AND REFRACTORY OXIDE BEING MIXED TOGETHER IN THE PROPORTIONS OF, BY WEIGHT, BETWEEN ABOUT 5 PERCENT AND 95 PERCENT OF THE ALKALINE EARTH CARBONATE AND THE BALANCE THE REFRACTORY OXIDE, FORMING THE MIXTURE WHILE OF PLASTIC CONSISTENCY INTO A CATALYST SUPPORT BODY OF HE DESIRED SHAPE, AND CALCINING THE SHAPED CATALYST SUPPORT BODY AT A TEMPERATURE BELOW THE DECOMPOSITION TEMPERATURE OF THE ALKALINE EARTH CARBONATE TO EXPEL THE WATER THEREFROM.
