Abstract: A process wherein an admixture of carbon monoxide and hydrogen is contacted over 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, and preferably at least about 3:2 to produce, at reaction conditions, a distillate fuel constituted principally of an admixture of linear paraffin and olefins, particularly a C.sub.10 + distillate which 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 C.sub.10 to about C.sub.20.

Abstract: A process for the preparation of liquid hydrocarbons from methanol by conversion of the methanol over a cobalt-titania catalyst, especially a thoria promoted cobalt-titania catalyst, particularly a cobalt-titania or cobalt-thoria-titania catalyst having a rutile:anatase weight ratio of at least 2:3. The methanol is contacted, preferably with added hydrogen, over said catalyst to produce, at reaction conditions, an admixture of C.sub.10 + linear paraffins and olefins, which can be further refined to high quality middle distillate fuels, and other valuable products such as mogas, diesel fuel, jet fuel, lubes and speciality solvents, especially premium middle distillate fuels of carbon number ranging from about C.sub.10 to about C.sub.20.

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 C.sub.10 + 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 C.sub.10 to about C.sub.20.
