CONVERSION OF PROPYLENE AND ISOBUTYLENE ON A HIGH SILICA ZEOLITE CATALYST

Abstract

As you know, over the past decade, due to the intensive increase in oil production, the number of gaseous hydrocarbons released at oil refineries and petrochemical plants has sharply increased. In this regard, the targeted conversion of gaseous hydrocarbons into valuable intermediates on zeolite catalysts is a topical issue. In the process of conversion of gaseous hydrocarbons, depending on the nature of the reagent and temperature, seal products of various structures can be formed on the catalyst surface. There are different opinions on the influence of the seal products on the catalyst activity. In some cases, the accumulation of SP on the catalyst surface adversely affects its activity, and in other cases, vice versa. In works devoted to the study of oligomerization and aromatization of C2-C4 olefins on zeolite catalysts, the question of the formation of SP was practically not considered. Keywords: isobutene, zeolite, seal products.
