Claims
- 1. A catalyst composition comprising a Group IIA metal component deposited onto the surface of a support containing at least one of a Group VIB metal component and rhenium component.
- 2. The composition of claim 1 wherein the catalyst contains magnesium component and said support is a solid inorganic refractory oxide containing a major proportion of alumina or silica.
- 3. The composition of claim 2 wherein the components are magnesium oxide and WO.sub.3 /SiO.sub.2.
- 4. A catalyst composition consisting essentially of a Group II A metal component deposited on the surface of a refractory metal oxide support containing major proportion of alumina or silica and at least one Group VI B metal component and rhenium component.
- 5. A catalyst component according to claim 4 wherein said Group II A component is deposited by precipitation or impregnation on the surface of said support and the surface area of said support ranges from about 25 m.sup.2 /g to 800 m.sup.2 /g.
- 6. A composition according to claim 5 wherein said Group II A component is magnesium oxide.
- 7. A composition according to claim 6 wherein said support is silica and said Group VI B metal component is tungsten oxide.
- 8. A composition according to claim 4 wherein the support contains from 0.1 to about 30 percent by weight of tungsten or molybdenum or rhenium component based on the combined weights of the support tungsten and molybdenum.
- 9. A composition according to claim 7 wherein said support is silica which contains from about 0.2 to about 30 percent by weight tungsten oxide based on the combined weights of silica and tungsten.
