摘要
考察了浸渍液的配制方法、钼含量、钴镍加入量、以及助剂镧对液化气脱烯烃脱硫催化剂活性的影响。实验表明,低温配制的浸渍液制备的催化剂低温低压活性好;钴镍加入量影响双功能;钼含量影响转化活性;镧的加入可提高催化剂加氢转化的活性稳定性。
Effects of impregnation solution preparation method,nickel content,cobalt and molybdenum rate,additive lanthanum on HYD and HDS catalyst activity were investigated.The results showed that the catalyst prepared by impregnation solution under the low temperature condition with a good low-temperature and low-pressure catalytic properties,nickel content,cobalt and molybdenum rate influenced catalytic activity,and adding a certain amount of additive lanthanum can improve the activity stability.
