Abstract
The acid and catalytic properties of ZSM-5 zeolites modified with tungsten heteropolycompounds were studied in the process of production of high-octane gasoline from straight-run gasoline. It was shown that introducing cobalt tungsten-bismuthate, cobalt tungsten-phosphate, and iron tungsten-phosphate heteropolycompounds in zeolite in amount of 1–3 wt % makes it possible to increase the yield of high-octane gasoline by 5–10% and that of alkyl aromatic hydrocarbons by 5–7% from straight-run gasoline compared to initial H-ZKE-G zeolite. The interrelation between acid and catalytic properties of zeolite catalysts modified with cobalt tungsten-bismuthate, cobalt tungsten-phosphate, and iron tungsten-phosphate heteropolycompounds was established for the process of producing high-octane gasoline from straight-run gasoline.
