“…Therefore, the Pt/zeolite catalysts display high activity but mainly as a result of high activity in the cracking reaction. It was reported that [68][69][70][71] that the channels of MOR and especially MFI framework are insufficiently large to enable the production of isomers. The paraffinic intermediates may have longer life time on acid sites and they undergo successive rearrangement and cracking to a large extent because it is difficult for them to leave the pores of the zeolite channels.…”

“…In the past, zeolitic catalysts have been extensively applied in pollution control, petroleum refining, and petrochemicals because of the acidities and pore structures of diverse zeolites . ZSM-5 is the most widely used active component and has been extensively used in catalytic reactions such as aromatization, alkylation, cracking, and isomerization of hydrocarbons because of its acidity, large surface area, and special three-dimensional pore structure. , The excellent catalytic performance of ZSM-5 has attracted extensive research in catalytic cracking to light olefins, where gaseous feedstocks, naphtha range, and heavy feedstocks can be used as different types of industrial feeds for the catalytic cracking reaction. Researchers also found that propylene yield can be increased by modifying ZSM-5 because acidity plays an important role in determining alkane conversion and product distribution . The major methods for acidity modification of ZSM-5 are through alkali treatment, phosphorus, alkaline earth metals (Na, Mg, K, and Ca), and rare earth metals (La and Ce) .…”

“…Typically, there are several types of zeolites applied in this process, such as ZSM-5, FER, CHA, FAU, and MOR. [16][17][18] In particular, the small pore size of ferrierite (FER) has been suitable for ethylene and propylene production because its cavities (0.35 × 0.48 nm) are fitted well with the molecular dimension of light olefins (0.39-0.45 nm). [19][20][21] Although over the past decades conventional zeolites have been developed for the manufacture of light olefins via catalytic cracking of hydrocarbons, they regularly suffer from some weaknesses, in particular, a fast catalyst deactivation from coke formation and a low selectivity of light olefins due to the interference of side reactions including isomerization, oligomerization, and aromatization.…”
