Development of effective catalysts for processing C3-C4 Hydrocarbons. [Текст] / S. R. Rasulov, G. R. Mustafayeva // News of national academy of sciences of the republic of Kazakhstan. . - 2021. - №3. - P. 87-93
ББК 35
Рубрики: chemical Technology
Кл.слова (ненормированные):
refinery gases -- 3-C4 hydrocarbons -- zeolite-containing catalyst -- modifiers -- reaction-regeneration cycles.
Аннотация: The aim of the article is to study the effect of preparation and activation methods of a modified zeolite-containing catalyst on the activity and stability of catalytic properties displayed by it during the conversion of C3-C4 hydrocarbons. During the experiment, the industrial cracking catalyst OMNIKAT, which is a zeolite in the sodium form, was used as the initial one. Zinc, gallium, and REE (rare earth elements) were sequentially applied to decationized samples of this catalyst by ion exchange, impregnation, and dry mechanical mixing, and the effect of these methods on the catalytic properties of the zeolite-containing catalyst was observed. As a result of a comparative analysis of the regularities of aromatization of C3-C4hydrocarbons, it was found that the mechanical mixing method is the most preferable, since it provides the best process performance.
