Abstract

The diffusion of n-octane and n-propylbenzene in mordenite and the molecularsieve selectivity in hydrocracking of octane-propylbenzene binary mixtures over a mordenite catalyst have been studied. The hydrocarbon diffusivities and molecular-sieve selectivity change are accounted for by diffusion through mordenite channel mouths poisoned with an easily adsorbable hydrocarbon.

Abstract

Исследована диффузия для бензола и н-октана в мордените, а также молекулярноситовая избирательность (МСИ) в гидрокрекинге бинарных смесей октан-пропилбензол. Предположено, что подвижность и МСИ характеристики углеводородов меняются в связи с диффузией в устье каналов морденитов, отравленных слабо адсорбированным углеводородами.
