    摘要: 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.The process according to the invention is particularly applicable to catalysts containing copper, cobalt and optionally aluminum and/or zinc and/or sodium.

    摘要: The invention concerns an isomerization catalyst comprising 4 to 15% of at least one halogen and at least one metal from group VIII deposited on a support composed of a mixture of specific proportions of eta alumina and gamma alumina. The invention also concerns a process for reducing the benzene content of gasoline fractions and isomerizing paraffins in the presence of this catalyst, in which isomerization is carried out on a mixture of a) a feed with the following composition by weight: 40% to 80% of paraffins, 0.5% to 7% of cyclic hydrocarbons and 6% to 45% of aromatics, and with a maximum distillation temperature of between 70.degree. C. and 90.degree. C., and b) a C.sub.5 -C.sub.6 cut which is generally a straight run cut.
