High temperature cracking of
hydrocarbons on the zeolite-containing catalysts
Abstract
The transformations of
decalene, tetralene and b-n-butylnaphtalene on microspherical
zeolite-containing catalysts at Deep Catalytic Cracking temperature (560oC)
have been studied. It has been established that nikel on the catalyst results
the increasing of the amount of unsaturated and aromatic compounds in cracking
products. The treatment of catalysts by antimony
tris-O,O-diisopropyldithiophosphate on the surface of allows to decrease
significantly the dehydrogenating activity of nikel.
