Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
107 words
THE PROCESS OF DESTRUCTIVELY HYDROGENATING A HYDROCARBON OIL WHICH COMPRISES CONTACTING SAID OIL WITH HYDROGEN AT AN ELEVATED TEMPERATURE AND SUPERATMOSPHERIC PRESSURE IN THE PRESENCE OF A CATALYST WHICH IS PREPARED BY IMPREGNATING A SILICA-ALUMINA CRACKING CATALYST BASE WITH AN AQUEOUS SOLUTION OF MOLYBDENUM PENTACHLORIDE AND DRYING AND CALCINING THE RESULTING MASS TO CONVERT THE IMPREGNANT INTO MOLYBDENUM TRIOXIDE, SAID MOLYBDENUM PENTACHLORIDE BEING DEPOSITED IN AN AMOUNT SUFFICIENT TO RESULT IN A CALCINED CATALYST CONTAINING BETWEEN ABOUT 0.5 AND ABOUT 4% MOLYBDENUM TRIOXIDE, SAID MOLYBDENUM TRIOXIDE BEING DEPOSITED IN AN AMOUNT SUFFICIENT TO RESULT IN A CALCINED CATALYST CONTAINING BETWEEN ABOUT .05 TO ABOUT 4% MOLYDBENUM TRIOXIDE.
