The present work reports for the first time a study of cracking of model parafIinic compounds in the boiling range of vacuum gas oil. The cracking reactions are investigated on commercial silica-alumina catalysts and rare earth exchanged Y zeolite (REY) using the ASTM procedure for microactivity tes

The catalytic cracking of a Gippsland reduced crude on a rare earth exchanged ultrastable Y zeolite is discussed. The cracking behaviour of this crude has only been reported previously for HY and H-ZSM-5 zeolites, and here turns to the use of more industrially applicable catalysts. Light gases and g
We present an X-ray photoemlsslon spectroscopy study of some rareearth ion(IU)excha Y-type z+oIites (Ln-u). The 4f levels of Eu-Y mere drastxally changed by degassmg at low temperature; the relatwe intensity of the 4f levels for Eu3 + decreased and the 4f lme of Eu'+ increased as the sample was dega
