Activation of hydrocarbon conversion catalysts

Claim 1

IN A PROCESS FOR CATALYTIC POLYMERIZATION TO SOLID POLYMERS OF A LOW MOLECULAR WEIGHT OLEFIN WITH AT LEAST ONE MATERIAL OF THE GROUP CONSISTING OF SAID OLEFIN AND OLEFINS POLYMERIZABLE THEREWITH EMPLOYING A CONTACT MASS FORMED BY IMPREGNATING AN INORGANIC SOLID SORBENT OF THE GROUP CONSISTING OF SILICA BASE SORBENTS, SORBENTS BASED UPON AMPHOTERIC METAL OXIDES, AND PHOSPHATE GELS WITH A SOLUTION OF VI GROUP METAL COMPOUND IN A SOLVENT OF THE GROUP CONSISTING OF WATER AND WATER-SOLUBLE ALCOHOLS: THE METHOD AF ACTIVATING SAID CONTACT MASS CONSISTING ESSENTIALLY OF IMMERSING THE CONTACT MASS IN AT LEAST ONE HYDROCARBON OF THE GROUP CONSISTING OF SATURATED OPEN CHAIN AND CYCLIC HYDROCARBONS, ALKYL BENZENES AND BENZENE WHICH HYDROCARBON HAS ATMOSPHERIC PRESSURE BOILING POINT IN THE RANGE BETWEEN ABOUT 65*C. AND ABOUT 155* C. AND BOILS ABOVE THE BOILING POINT OF ITS MIXTURE WITH SAID SOLVENT USED FOR IMPREGNATION; BOILING AND TAKING OFF VAPORS OF SAID HYDROCARBON AND SAID SOLVENT AND REMOVING SAID SOLVENT EVOLVED AS VAPOR DURING SAID BOILING; AND CONTINUING SAID BOILING AND SAID TAKING OFF AND REMOVAL OF VAPORS WHILE MAINTAINING SAID CONTACT MASS IMMERSED IN A LIQUID PHASE OF SAID HYDROCARBON AT LEAST UNTIL SAID CONTACT MASS IS ACTIVATED TO THE POINT THAT IT WILL POLYMERIZE ETHYLENE AT TEMPERATURES OF ABOUT 30*C. AND PRESSURE OF ONE ATMOSPHERE ABSOLUTE AND IN PRESENCE OF A WEIGHT OF ALUMINUM TRIISOBUTYL EQUAL TO THE WEIGHT OF SAID CONTACT MASS, AT RATE OF AT LEAST 0.5 GRAM OF POLYMER FORMATION PER HOUR PER GRAM OF CONTACT MASS; SAID LIQUID PHASE OF HYDROCARBON IN WHICH THE CONTACT MASS IS IMMERSED AT THE END OF SAID ACTIVATION BEING THE REACTION MEDIUM FOR THE SUBSEQUENT CATALYTIC POLYMERIZATION.
