Abstract:The catalytic properties of four large-pore (H−Y, H-beta, Hmordenite, and H-UZM-35) and three medium-pore (H-NU-87, H-TNU-9, and H-ZSM-5) zeolites for the transalkylation of iso-propylbenzene (iPB) with toluene are investigated. Among the zeolite catalysts employed here, H-UZM-35 with a 12 × 10 × 10-ring channel system was found to exhibit a comparable cymenes yield to that of H-beta with a 12 × 12 × 12-ring channel system, the most widely studied catalyst for this reaction. GC-MS analysis reveals that monomet… Show more
Locations of Brønsted acids confined in the 10-ring channel of ferrierite have been unravelled by refining structural models of as-made and probe-molecule-adsorbed samples against powder X-ray diffraction data, respectively.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
