Abstract: A zirconium, hafnium, cerium or uranium promoted cobalt catalyst and process for the conversion of methanol or synthesis gas to hydrocarbons. Methanol is contacted, preferably with added hydrogen, over said catalyst, or synthesis gas is contacted over said catalyst to produce, at reaction conditions, an admixture of C.sub.10 + linear paraffins and olefins. These hydrocarbons can be further refined to high quality middle distillate fuels, and other valuable products such as mogas, diesel fuel, and jet fuel, particularly premium middle distillate fuels of carbon number ranging to about C.sub.20.

Abstract: The present invention concerns a process of use of a copper and cobalt-containing catalyst for synthesizing saturated primary aliphatic alcohols. This process comprises a first step consisting in at least one catalyst prereduction by means of a gas mixture containing a reducing compound, a second step wherein the prereduced catalyst is contacted with a mixture of hydrogen and carbon oxides (CO, CO.sub.2) for at least 10 hours, so as to produce a mixture of alcohols; a third step wherein the catalyst obtained in the second step is subjected to a treatment with a gas mixture containing a single reducing gas, during about 1 to 400 hours and a fourth step of synthesizing saturated primary aliphatic alcohols from a mixture containing hydrogen and carbon oxides.Optionally the process also comprises an additional step consisting of subjecting the catalyst, whose activity and/or selectivity has been partially lost, to a new treatment according to the procedure defined for the third step.

Abstract: Methanol is prepared by catalytic conversion of a synthesis gas mixture, containing hydrogen, carbon monoxide, carbon dioxide and/or water, at from 200.degree. to 320.degree. C. and under from 30 to 300 bar in adiabatic and/or isothermal reactions in the presence of a catalyst containing copper and zinc, by a process in which the fresh catalyst is reduced with a hydrogen-containing gas before the start-up of the process, and then the synthesis is started under conventional conditions and is continued until the formation of methanol in the reaction zone has declined substantially, after which the reaction is interrupted and the catalyst is regenerated.

Abstract: A method for the preparation of hydrocarbons and oxygenated hydrocarbons which comprises contacting a gaseous mixture of carbon monoxide, hydrogen and oxygen with a catalyst comprising a metal of Group VII or Group VIII of the Periodic Table, the amount of oxygen not exceeding 10% by volume based on the volume of hydrogen.

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: This invention relates to the treatment of carbon-containing materials. In one aspect this invention relates to the treatment of carbon-containing materials, such as coal, coke and hydrocarbons to produce oxides of carbon therefrom. In still another aspect, this invention relates to a process for the production of high purity synthesis gas, a mixture of hydrogen and carbon monoxide, from carbon-containing materials. More specifically, this invention relates to inorganic metal-oxygen containing materials useful as the oxidant, oxygen carrier and supplier, and heat transfer agent for the endothermic oxidative gasification of carbon-containing materials.
