Claim 1
Independent Claim
142 words
A METHOD OF HYDROCRAKING HIGH MOLECULAR WEIGHT HYDROCARBONS CONTAINING SULFUR AND NITROGEN COMPOUNDS WHICH COMPRISES CONTACTING SAID HYDROCARBONS AT TEMPERATURES IN THE RANGE OF FROM 400* PSIG TO 1,200* F. AT PRESSURES IN THE RANGE OF FROM 100 PSIG TO 5,000 PSIG WITH FROM 100 TO 5,000 STANDARD CUBIC FEET OF HYDROGEN PER BARREL OF HYDROCARBON CHARGE IN THE PRESENCE OF A CATALYST SOLUBLE IN SAID HYDROCARBONS AT SAID TEMPERATURES, SAID CATALYST BEING PRODUCED FROM A MIXTURE OF ALUMINUM CHLORIDE AND PALLADIUM CHLORIDE WHEREIN IN THE PALLADIUM CHLORIDE-ALUMINUM CHLORIDE CATALYST THE PALLADIUM RANGES FROM 0.001 TO 1.0 WEIFHT PER CENT BASED ON THE WEIGHT OF THE HYDROCARBON CHARGE AND THE ALUMINUM CHLORIDE RANGES FROM 0.005 TO 10.0 WEIGHT PER CENT BASED ON THE WEIGHT OF THE HYDROCARBON CHARGE WITH THE MOLAR RATIO OF ALUMINUM CHLORIDE TO PALLADIUM CHLORIDE BEING AT LEAST 2:1.
