Abstract:
This research was studied the characteristic of mixed Oxides of MesoporusTitania with Silica, Alumina and Zirconia and also the efficiency of cobalt catalyst in the hydrogenation of carbon dioxide reaction. Mixed Oxides was prepared by oxidation of Titanium carbide with 5 M of Nitric Acid at 70๐C for 8 hr. The mixed oxide was added in step of oxidation and hydrolysis at the ratio 1:1 and 2:1 respectively. And it was found that the characteristic of mixed oxides that added the silica, alumina and zirconia in the mesoporous titania in the step of oxidation at the ratio 2:1 show the larger surface than mesoporous titania and also highest surface at 196.13, 236.20, 195.25 m2/g respectively. On the application of these mixed oxides as support for cobalt catalyst in the hydrogenation reaction of carbon dioxide was found that all catalyst produced main product as methane and by product (C₂-C₃) except the cobalt catalyst that added the alumina in the step of oxidation at the ratio 1:1. The highest Conversion was 100% that from this cobalt catalyst. In addition, Not found the reverse water gas shift reaction in all catalysts also.
