Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
100 words
A METHOD OF CONVERTING HIGHER BOILING HYDROCARBONS TO LOWER BOILING GASOLINE HYDROCARBONS OF LOW SULFUR AND LOW OLEFIN CONTENT WHICH COMPRISES HYDROCRACKING GAS OIL BOILING IN THE RANGE OF ABOUT 450* TO 910* F. AT A TEMPERATURE BETWEEN ABOUT 975* AND 1035*F. UNDER A PRESSURE BETWEEN ABOUT 200 P.S.I.G. AND 700 P.S.I.G. IN THE PRESENCE OF PLATINUM ON ETA ALUMINA CATALYST AND AT A FEED RATE BETWEEN ABOUT 0.5 AND 8 W./HR./W. AND IN THE PRESENCE OF BETWEEN ABOUT 3000 AND 15,000 SCF OF HYDROGEN PER BARREL OF GAS OIL FEED, THE ETA ALUMINA BEING PRODUCED FROM AN ALUMINUM ALCHOLATE.
