一、前言SL—1型催化剂是我国自己研制成功的一种镍系粘结型催化剂。它用于烃类转化制氢,为合成氨和石油加工工业提供原料。SL—1型催化剂的主要成分是Ni、Mg、Al、Fe等,其中Ni为活性组分,另有矾土水泥作粘结剂,流动钾作为抗结炭组分。实践证明SL—1型催化剂的活性、抗结炭性能、热稳定性以及机械强度等均能保证在工业生产中长期稳定地使用。本文对不同运转时间的SL—1型催化剂(其中包括只经还原未经运转的新鲜催化
First, the foreword SL-1 type catalyst is our own successful development of a nickel-based bond type catalyst. It is used for the conversion of hydrocarbons to hydrogen, for the ammonia and petroleum processing industries to provide raw materials. The main components of SL-1 type catalyst are Ni, Mg, Al, Fe, etc., among which Ni is the active component, another alumina cement is used as the binder, and the mobile potassium is used as the anti-carbon component. It has been proved that the activity of SL-1 catalyst, anti-coking property, thermal stability and mechanical strength all can ensure the long-term stable use in industrial production. In this paper, SL-1 catalyst with different operating time (including only fresh catalyst
