摘要

合成了一系列负载在混合沸石上的双功能钴复合催化剂,以提高其对富含支链烃的液体燃料的选择性。考虑到催化剂是用氧化铝粘结剂制备的,混合沸石由两个分子筛组成,成品样品通常为Co-Al2O3 /SiO2 + [ZSM-5 + (ZSM-23, Beta, SAPO-11)] + Al2O3。在240℃、2.0 MPa、H2/CO比为2:1、合成气每小时空速(GHSV)为1000 h-1的条件下,对催化剂进行了费托合成试验。负载在ZSM-5+ β上的催化剂对C5-C10的选择性最高。结果表明,ZSM-5+ zsm -23负载型催化剂对支链烃的选择性最强,这反过来又有利于生产具有最佳低温性能的柴油馏分。

Dual-Zeolite Catalysts for Synthesis of Liquid Hydrocarbon Fuels

Dual-Zeolite Catalysts for Synthesis of Liquid Hydrocarbon Fuels

A series of bifunctional cobalt composite catalysts supported on mixed zeolites were synthesized to enhance the selectivity towards liquid fuels rich in branched hydrocarbons. Given that the catalysts were prepared with an alumina binder and that the mixed zeolites consisted of two molecular sieves, the finished samples were generally formulated as Co–Al2O3/SiO2 + [ZSM-5 + (ZSM-23, Beta, SAPO-11)] + Al2O3. The catalysts were tested in Fischer–Tropsch synthesis at 240°C, 2.0 MPa, an H2/CO ratio of 2 : 1, and a syngas hourly space velocity (GHSV) of 1000 h–1. The catalyst supported on ZSM-5+Beta exhibited the highest selectivity towards C5–C10 hydrocarbons. The ZSM-5+ZSM-23-supported catalyst turned out to be the most selective towards branched hydrocarbons, which, in turn, favored the production of a diesel fraction with optimal low-temperature properties.

期刊介绍: Petroleum Chemistry (Neftekhimiya), founded in 1961, offers original papers on and reviews of theoretical and experimental studies concerned with current problems of petroleum chemistry and processing such as chemical composition of crude oils and natural gas liquids; petroleum refining (cracking, hydrocracking, and catalytic reforming); catalysts for petrochemical processes (hydrogenation, isomerization, oxidation, hydroformylation, etc.); activation and catalytic transformation of hydrocarbons and other components of petroleum, natural gas, and other complex organic mixtures; new petrochemicals including lubricants and additives; environmental problems; and information on scientific meetings relevant to these areas. Petroleum Chemistry publishes articles on these topics from members of the scientific community of the former Soviet Union.
