Aromatization reforming and catalysts for effecting the same

Claim 1

A PROCESS FOR EFFECTING AROMATIZATION REFORMING OF HYDROCARBON MIXTURES CONTAINING AROMATIZABLE HYDROCARBONS, WHICH COMPRISES CONTACTING SAID HYDROCARBONS, MIXTURE WITH A CHROMIUM OXIDE-IRON GROUP METAL OXIDE CATALYST COMPOSITION OBTAINED BY INITIALLY INTIMATELY MIXING MOIST, UNDRIED HYDROUS CHROMIUM OXIDE WITH MOIST, UNDRIED HYDROUS IRON GROUP METAL OXIDES IN PROPORTIONS SUCH THAT THE FINAL CHROMIUN OXIDE-IRON GROUP METAL OXIDE CATALYST COMPOSITION WILL CONTAIN CHROMIUM OXIDE AND IRON GROUP METAL OXIDE IN A MOL PER CENT RATIO, EXPRESSED ON THE BASIS OF THE METAL SESQUIOXIDES, VARYING BETWEEN ABOUT 40:60 AND ABOUT 70:30, RESPECTIVELY, TO PRODUCE A MIXTURE; TREATING SAID MIXTURE AT TEMPERATURES SUFFICIENT TO DRY THE MIXTURE BUT BELOW ABOUT 350* C. TO PRODUCE A DEHYDRATED MIXTURE; COMMINUTING SAID DEHYDRATED MIXTURE; AND CALCINING SAID DEHYDRATED MIXTURE AT TEMPERATURE PERATUES VARYING BETWEEN ABOUT 500* C. AND ABOUT 600* C., UNDER NON-OXIDIZING CONDITIONS AND FOR A PERIOD OF TIME OF AT LEAST ABOUT FIVE HOURS; AT TEMPERATURES FALLING WITHIN THE RANGE VARYING BETWEEN ABOUT 450* C. AND ABOUT 650* C. AT HYDROCARBON PARTIAL PRESSURES FALLING WITHIN THE RANGE VARYING FROM ATMOSPHERIC AND UP TO ABOUT 30 POUNDS PER SQUARE INCH GAUGE; AT LIQUID HOURLY SPACE VELOCITIES FALLING WITHIN THE RANGE VARYING BETWEEN ABOUT 0.2 AND ABOUT 2.5; AND UNDER TOTAL PRESSURES VARYING FROM ATMOSPHERIC AND UP TO ABOUT 300 POUNDS PER SQUARE INCH GUAGE.
