Features of coke formation on organically modified zeolite catalysts of oil refining

Abstract In this paper, we propose one of the ways to increase the octane number of gasolines using organically modified catalysts as contacts of the upgrading process. Materials and methods The sample FeЦВК (silicate module 35, Fe3+ 0.2%; sample FeMnЦВК (silicate module 35, 0.2% Fe3+ and Mn2+) Results In the course of the research it was found that additional modification of the initial samples of organically modified zeolite- containing catalysts with iron and manganese reduces the rate of coke formation during the refinement of straight-run gasoline fractions. Conclusions The rate of coke formation increases with the increase in the silicate module of the zeolite. Iron applied to the catalyst in a small amount helps suppress the compaction and coking reactions, prolonging the eff e life of the organically modifi zeolite catalyst.
