C_5、C_6轻质烷烃的异构化,就是在催化剂的作用下将低辛烷值的C_5和C_6正构烃转化为高辛烷值的C_5和C_6异构烃。这一工艺国外早已实现工业化了。为了尽快在我国发展烷烃异构化工艺,对其催化剂进行广泛深入的研究是非常必要的。本文以丝光沸石为载体,详细考察了钠含量,硅铝比、铂含量以及活化条件等制备因素对催化剂活性的影响,从而制成了性能较好的Pt-HM催化剂。260℃戊烷异构化率达66—68%。 The isomerization of C_5 and C_6 light paraffins is the conversion of low octane C_5 and C_6 normal hydrocarbons to high octane C_5 and C_6 isoparaffins under the action of catalysts. This process has long been industrialized abroad. In order to develop the paraffin isomerization process in our country as soon as possible, it is necessary to conduct extensive and in-depth research on its catalyst. In this paper, Mordenite as a carrier, a detailed examination of the sodium content, the ratio of silica to alumina, platinum content and activation conditions and other factors on the catalytic activity of the catalyst, resulting in a better performance Pt-HM catalyst. 260 ℃ pentane isomerization rate of 66-68%.
