Abstract

Abstract A cobalt catalyst, especially a thoria promoted cobalt catalyst, formed by dispersing the cobalt, or cobalt and thoria, upon a titania or titania-containing support wherein the titania support is one having a rutile:anatase ratio of at least about 2:3. By passing methanol, or an admixture of carbon monoxide and hydrogen over the catalyst at reaction conditions, a distillate fuel constituted principally of an admixture of linear paraffin and olefins, particularly a C10+ distillate can be formed. The distillate can be further refined and upgraded to high quality fuels, and other products such as mogas, diesel fuel, jet fuel, lubes and specialty solvents, particularly premium middle distillate fuels of carbon numbers ranging from about C10 to about C20.

Claims Analysis

Total Claims: 19
Claim 1
Independent Claim 49 words
A catalyst composition useful for the conversion of methanol or synthesis gas to hydrocarbons which consists essentially of cobalt, or cobalt and thoria in catalytically active amount composited with titania or a titania-containing support, wherein the titania support is one having a rutile:anatase ratio of at least about 2:3.
Claim 2
Dependent Claim 49 words
A catalyst composition useful for the conversion of methanol or synthesis gas to hydrocarbons which consists essentially of cobalt, or cobalt and thoria in catalytically active amount composited with titania or a titania-containing support, wherein the titania support is one having a rutile:anatase ratio of at least about 2:3.
Claim 3
Dependent Claim 36 words
