Improved cobalt catalysts, useful for the preparation of hydrocarbons from synthesis gas or methanol, and processes using the catalysts

摘要

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,o+- containing distillate can be formed.
