MYI-2001型催化裂化催化剂水蒸汽老扮装置
催化剂的老化失活是研讨催化剂反响的一个紧张题目。影响催化剂失活的缘故原由是催化剂在工艺安装中处于存在水蒸汽氛围的低温情况中,使催化剂原始粒子布局的分列改动,致使外表积变小,孔散布变粗。该催化剂水蒸汽老扮装置是在肯定温度、分压、空速、处置工夫条件下,对催化剂举行老化处置的实行室安装,从实验可失掉与产业均衡剂某些功能和布局类似的后果。
Catalytic cracking catalyst vapour ageing unit:
The ageing deactivation of the catalyst is a important problem to research catalyst reaction.The reason that affects the catalyst activation ys that the high temperature of the aqueous vpour changes the stercture and order of the molecules,so the surface area of the catalyst is decreased and the pore distribution ys more broad .This unit is a laboratory device to age the fractiona pressure ,the space velocity ,and the dealing time .Theresult of the test is similar with the properties and structures of equilibrium reagents.
