Production of blown asphalts in the presence of a phosphorous containing catalyst

Claim 1

THE METHOD OF CATALYST OXIDIZING SUITABLE HIGH MOLECULAR WEIGHT HYDROCARBONS TO PRODUCE BLOWN ASPHALTS, WHICH METHOD COMPRISES CONTACTING SAID HIGH MOLECULAR WEIGHT PETROLEUM HYDROCARBONS WITH SUBSTANTIAL QUANTITIES OF AIR AT A TEMPERATURE IN THE RANGE OF FROM ABOUT 400* TO ABOUT 500*F. FOR A PERIOD OF AT LEAST ABOUT ONE-HALF HOUR,SUBSEQUENTLY INTRODUCING A FLUID HOMOGENEOUS SLURRY OF A PHOSPHORUS-CONTAINING CATALYST SELECTED FROM THE GROUP CONSISTING OF PHOSPHORUS PENTOXIDE, STABLE PHOSPHORUS SULFIDES AND RED PHOSPHORUS IN A HYDROCARBON SLURRY OIL TO SAID HIGH MOLECULAR WEIGHT PETROLEUM HYDROCARBONS WHILE AT SUCH A TEMPERATURE, THE AMOUNT OF SAID PHOSPHORUS-CONTAINING CATALYST BEING FROM ABOUT 0.1 TO ABOUT 5.0% BASED UPON THE TOTAL WEIGHT OF HIGH MOLECULAR WEIGHT PETROLEUM HYDROCARBONS AND HYDROCARBON SLURRY OIL PRESENT, AND CONTINUING THE INTRODUCTION OF AIR TO THE RESULTING ADMIXTURE OF CATALYST, HYDROCARBON SLURRY OIL AND HIGH MOLECULAR WEIGHT PETROLEUM HYDROCARBONS.

Claim 2

THE METHOD OF CATALYST OXIDIZING SUITABLE HIGH MOLECULAR WEIGHT HYDROCARBONS TO PRODUCE BLOWN ASPHALTS, WHICH METHOD COMPRISES CONTACTING SAID HIGH MOLECULAR WEIGHT PETROLEUM HYDROCARBONS WITH SUBSTANTIAL QUANTITIES OF AIR AT A TEMPERATURE IN THE RANGE OF FROM ABOUT 400* TO ABOUT 500*F. FOR A PERIOD OF AT LEAST ABOUT ONE-HALF HOUR,SUBSEQUENTLY INTRODUCING A FLUID HOMOGENEOUS SLURRY OF A PHOSPHORUS-CONTAINING CATALYST SELECTED FROM THE GROUP CONSISTING OF PHOSPHORUS PENTOXIDE, STABLE PHOSPHORUS SULFIDES AND RED PHOSPHORUS IN A HYDROCARBON SLURRY OIL TO SAID HIGH MOLECULAR WEIGHT PETROLEUM HYDROCARBONS WHILE AT SUCH A TEMPERATURE, THE AMOUNT OF SAID PHOSPHORUS-CONTAINING CATALYST BEING FROM ABOUT 0.1 TO ABOUT 5.0% BASED UPON THE TOTAL WEIGHT OF HIGH MOLECULAR WEIGHT PETROLEUM HYDROCARBONS AND HYDROCARBON SLURRY OIL PRESENT, AND CONTINUING THE INTRODUCTION OF AIR TO THE RESULTING ADMIXTURE OF CATALYST, HYDROCARBON SLURRY OIL AND HIGH MOLECULAR WEIGHT PETROLEUM HYDROCARBONS.
