Abstract: Catalytic reactions of methylcyclopentane have been studied on HY Zeolite at 500°C. Initial reactions include ring cleavage, the formation of paraffins and the formation of methylcyclopentane. Aromatic species are formed as both primary and secondary products. In contrast to the reaction of methylcyclopentane under reforming conditions, benzene is not a dominant initial aromatic product formed under cracking conditions. Unlike the reaction of cyclopentane on HY, the cracking of methylcyclopentane produces mole… Show more

“…[1][2][3][4] The Brønsted acid site has been established as the primary active site for zeolite catalysis; however, little is still known of the mechanistic details for reactions occurring at these sites. For instance, in zeolite catalyzed cracking, isomerization, and alkylation of hydrocarbons, most proposed mechanisms involve proton transfers from the Brønsted site to the hydrocarbon adsorbate to form carbonium (pentacoordinated carbocations) or carbenium ions (tricoordinated carbocations) as reactive intermediates; [5][6][7][8][9] however, there is still little empirical confirmation of the nature of these intermediates.…”

“…As shown in Fig. The phenomenon that TOF shows maximum by matching the volume of the zeolite cavity to that of C 5 The TOFs over aluminophosphate molecular sieves, such as SAPO-41, were nearly equal to 3-4 h À1 , which were about 10-100 times lower than those over aluminosilicate molecular sieves, as shown in Table 7. The TOF was maximum at a spatial cavity volume of around 0.15 nm 3 .…”
