    • 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.
    • 本发明涉及使用含铜和钴的催化剂合成饱和伯脂肪醇的方法。 该方法包括通过含有还原化合物的气体混合物进行至少一种催化剂预还原的第一步骤,其中将预还原的催化剂与氢和碳氧化物(CO,CO 2)的混合物接触至少10 小时,以产生醇的混合物; 第三步骤,其中将第二步中得到的催化剂在含有单一还原气体的气体混合物中进行约1-4小时的处理,以及从含有氢和碳氧化物的混合物中合成饱和伯脂肪醇的第四步骤 。 任选地,该方法还包括另外的步骤,该方法包括将其活性和/或选择性已被部分丧失的催化剂按照根据第三步所定义的方法进行新的处理。 根据本发明的方法特别适用于含有铜,钴和任选的铝和/或锌和/或钠的催化剂。
