Claim 1
Independent Claim
131 words
THE METHOD OF PREPARING A CATALYST COMPRISING TITANIUM SUBCHLORIDE DEPOSITED ON A SOLID ALUMINIFEROUS MATERIAL WHICH COMPRISES FEEDING VAPORS OF TITANIUM TETRACHLORIDE INTO A REACTION ZONE CONTAINING AN INTIMATE, COMMINUTED MIXTURE OF A MINOR QUANTITY OF METALLIC TITANIUM AND A MAJOR QUANTITY OF SAID ALUMINIFEROUS MATERIAL IN AN INERT GASEOUS ATMOSPHERE, WHILE MAINTAINING THE TEMPERATURE OF THE REACTION ZONE AT 137*C. TO 700* C., THE DISCONTINUING FEEDING OF THE TETRACHLORIDE WHEN THE ALUMINFEROUS MATERIAL HAS HAD DESPOSITED THEREUPON FROM 0.01 PERCENT TO 15.0 PERCENT OF TITANIUM SUBCHLORIDE BASED ON THE WEIGHT OF THE ALUMINFEROUS MATERIAL. 3 A CATALYST FOR HYDROCARBON CONVERSION PROCESSES CONSISTING ESSENTIALLY OF TITANIUM SUBCHLORIDE BEING FROM A SOLID ALUMINIFEROUS MATERIAL, THE SUBCHLORIDE BEING FROM 0.01 PERCENT TO 15.0 PERCENT BY WEIGHT OF THE WEIGHT OF THE ALUMINIFERIOUS MATERIAL.
