Abstract

The effect the content of rare-earth elements has on thermostable and catalytic properties of HREEY zeolite in the composition of a catalyst matrix consisting of bentonite clay, amorphous aluminosilicate, and aluminum hydroxide is considered. It is established that when the content of rare-earth elements is increased from 0 to 6.5 wt %, the thermostability of the zeolite rises by approximately 100°C. It is shown that increasing the content of rare-earth elements in the catalyst from 0 to 2 wt % raises the conversion of vacuum gasoil by 8 wt %. An acceptable 77–78% level of the conversion of raw materials is achieved when the REE content in the catalyst is approximately 0.5 wt %. The dependence of the contribution from hydrogen transfer reactions to the REE content in the cracking catalyst is shown as an example of a change in iso-butane content in the sum of formed C4-hydrocarbons. Based on laboratory data, a technique for the production of bizeolite cracking catalysts with reduced contents of REEs (M, N brands) is developed and introduced for catalyst production at JSC Gazpromneft-Omsk Oil Refinery.
