TL;DR: In this paper, it was shown that the cracking activity of MCM-41 for a reaction catalyzed by strong acids site, such as n-heptane cracking, is much lower than that of a USY zeolite, and similar to that of amorphous silica-alumina.

TL;DR: In this article, the effect of the pore topology of a catalytic catalyst on product distribution was investigated using a set of zeolites with medium-sized and large pore sizes.

TL;DR: In this paper, the catalytic activity, selectivity, catalyst decay, thermal and hydrothermal stability, and acidity of H-Beta and HY zeolites with Si Al ratios of 7.5 and 10, respectively, have been studied during cracking of n-heptane at 450 °C and atmospheric pressure.

TL;DR: A large variety of zeolite topologies including: large pore tridirectional (Beta), large pores unidirected (Mordenite, SSZ-24), bidirectional 10 member ring pores (MRP) (ZSM-5), and independent 12 MR cavities connected by 10 MR windows (MCM-22) have been studied as catalysts for the cracking of a gasoline range model molecule (n -heptane) as discussed by the authors.

TL;DR: In this article, the influence of zeolite Y catalyst and process variables (i.e., framework Si Al ratio and procedure of dealumination, time on stream, and contact time) on the formation of products responsible for motor and research octane of gasoline during cracking, namely branched, aromatics, and olefins were studied.
