High-Temperature cracking of hydrocarbons on zeolite-containing catalysts

摘要

Transformations of decalin,tetralin,and beta-n-butylnaphthalene on a microspherical zeolite-containing catalyst at the temperature of deep catalytic cracking (560 deg C) were studied.It was found that the presence of nickel on the catalyst led to the growth of the concentrations of unsaturated and aromatic compounds in the products.The application of antimony tris-(O,O-diisopropyldithiophosphate) to the catalyst made it possible to attenuate greatly the dehydrogenating activity of nickel.
