水蒸汽处理条件对降凝催化剂α值的影响

THE EFFECT OF STEAM TREATING CONDITION ON αVALUE OF THE CATALYST IN DROPPING SOLIDIFYING POINT

在不同条件下对降凝催化剂进行水蒸汽处理，恒温下测定催化剂α值，得出水蒸汽含量、处理温度和时间对降凝催化剂初活性的影响规律，从中找出最佳的水蒸汽处理条件。

Abstract The catalysts in dropping solidifying point were treated by steam in different condi-tions and their α values were measured at constant temperature so that the affecting reg-ularities of content,treating temperature and treating time on original activity of thecatalyst in dropping solidifying point were obtained and the best steam treating conditionwas also found.SUBJECT TERMS:catalyst,steam treatment,the catalyst in dropping solidifying point,α value
