【Abstract】 The effect of reaction conditions and catalyst performances on the dehydrogenation of 1,4-butanediol toγ-Butyrolactone over the CuO-ZnO-Al₂O₃ catalysts at normal pressure was studied and the stability of catalyst was also observed. The results showed that the conversion of 1,4-butanediol could be above 99.9% with a 99.6% selectivity toγ-Butyrolactone over the best CuO-ZnO-Al₂O₃ catalyst at optimized reaction conditions. It is predicted that the life of the catalyst will be over one year.更多还原
