متن کاملVacuum residue upgrading by pyrolysis-catalysis procedure over mesoporous ZSM-5 zeolite
A systematic study of two-staged upgrading process of vacuum residue for light fuel production has been carried out in a semi-batch binary reactor apparatus over Y, ZSM-5 and alkaline treated ZSM-5 zeolites. Prepared catalyst samples were characterized with XRD and BET. Density and Viscosity physical properties parameters estimation, as well as GC/SIMDIS analyses were conducted on liquid produc...
متن کاملExperimental Evidence on the Formation of Ethene through Carbocations in Methanol Conversion over H-ZSM-5 Zeolite.
The methanol to olefins conversion over zeolite catalysts is a commercialized process to produce light olefins like ethene and propene but its mechanism is not well understood. We herein investigated the formation of ethene in the methanol to olefins reaction over the H-ZSM-5 zeolite. Three types of ethylcyclopentenyl carbocations, that is, the 1-methyl-3-ethylcyclopentenyl, the 1,4-dimethyl-3-...
متن کاملFormation of acetone enol on acidic zeolite ZSM-5 evidenced by H/D exchange.
H/D exchange observed between bridging hydroxyl groups in acidic zeolite ZSM-5 and adsorbed acetone (acetone-d6/H-ZSM-5 and 13C-2-acetone/D-ZSM-5) indicates a concerted catalytic function of Brønsted acid sites and neighbouring framework oxygen atoms acting as Lewis base sites.
متن کاملZeolite ZSM-5 Membranes Grown on Porous a-A1203
Zeolites have found widespread applications as catalysts and separation media. A L present, all technologies exploiting these materials use the zeolite in powder composite form. The desire to translate the molecular sieving properties of zeolite powder composites into a membrane configuration has long been recognized. To prepare such a membrane, the crystals must grow in an interlockng fashion ...
