Cracking of vacuum gas oil on hlay -containing catalysts with a multicomponent matrix based on montmorilionite. [Текст] / A. K. Akurpekova // News of national academy of sciences of the republic of Kazakhstan. . - 2021. - №4. - P. 6-13

Кл.слова (ненормированные):
catalytic cracking -- montmorillonite -- binder -- strength -- gasoline -- zeolite -- acidity -- acuum gas oil
Аннотация: it is shown that additions of montmorillonite in the Na form contribute to a significant increase in the crushing strength of granules of cracking catalysts while maintaining their activity in the yield of gasoline. Comparison of the results of the cracking of vacuum gas oil on catalysts of the same composition, but with and without a NaMM binder, showed that the introduction of NaMM does not significantly affect the gasoline yield. Samples of catalysts of the same composition, but with the use of Al-pillared MM in Na-and CaNa-exchangeable forms and with the addition of NaMM as a binder, showed similar activity in the yield of gasoline, which is explained by the similarity of the elemental compositions, textural and acidic properties of the studied catalysts. The maximum yield of gasoline, equal to 44.8% and light gas oil of 14.6%, was obtained for Al (2.5) CaNaHMM + NaMM with the addition of a binder and crushing strength of 60-70 N / cm2.
