Abstract: 1. PROCESS FOR THE PRODUCTION OF ALUNIMUM CHLORIDE WHICH COMPRISES REACTING CHLORINE AT A TEMPERATURE OF BETWEEN ABOUT 450*-800* C. WITH ALUMINA HAVING AN AVERAGE ALPHA ALUMINA BEING INTERMIXED WITH CARBON AND WEIGHT AND AN AVERAGE SURFACE AREA OF AT LEAST ABOUT10 M.2/G., SAID ALUMINA BEING INTERMIXED WITH CARBON AND COMPOSITELY HAVING AN AVERAGE HYDROGEN CONTENT OF LESS THAN ABOUT 0.5% BY WEIGHT AND AN AVERAGE CARBON CONTENT OF ABOUT 15-24% BY WEIGHT BASED ON THE TOTAL ALUMINA, CARBON AND HYDROGEN CONTENTS PRESENT, TO FORM A GASEOUS EFFLUENT CONTAINING ALUMINUM CHLORIDE AND CARBON OXIDES IN WHICH AT LEAST ABOUT 25% BY WEIGHT OF SUCH CARBON OXIDES IS CARBON DIOXIDE, AND RECOVERING THE ALUMINUM CHLORIDE FROM THE GASEOUS EFFLUENT.

Abstract: Process for the preparation of selectively constituted carbon impregnated alumina through the thermal cracking of hydrocarbon in contact with a fluidized bed of particles of precoated high surface area alumina in a first zone to deposit carbon in situ thereon in conjunction with the deposition of residual crackable hydrocarbon from the first zone gaseous effluent on particles of uncoated high surface area alumina in a second zone and prior to their introduction into said first zone, and minimization of the amounts of free hydrogen attendant the resultant carbon impregnated product.
