用于脱氢反应的新型覆炭镍催化剂

Carbon Covered Ni Catalysts for Dehydrogenation

建立了一套制备覆炭载体的装置，制备了覆炭Ａｌ２Ｏ３新型载体。同时，考察了时间及温度对载体覆炭的影响。试验表明，采用浸渍法制备Ｎｉ／ＣＣＡ催化剂是可行的，并且Ｎｉ／ＣＣＡ的脱氢活性优于Ｎｉ／Ａｌ２Ｏ３。

An experimental device for preparing carbon covered catalyst carrier was used to prepare carbon covered Al 2O 3 carrier (CCA).The factors affecting the extent of carbon covered on the carriers was investigated by means of changing reaction temperature and time.Impregnation of CCA using a solution containing Ni compound was found feasible.The results of test on the activity of dehydrogenation show that Ni/CCA catalysts are better than Ni/Al 2O 3 catalysts.
