Abstract: THIS INVENTION RELATES TO A METHOD FOR MANUFACUTRING A CATALYST AND ITS CARRIER HAVING A VACANT CENTER OR A DENSE CENTER. SUCH A CARRIER IS MADE INTO PELLET FORM BY COVERING A DESIRED CORE WITH A FINELY DIVIDED MATERIAL, DRYING AND CALCINING THE RESULTANT PELLET. SUCH A CATALYST IS MADE OF A CARRIER TO WHICH A SOLUTION CONTAINING A CATALYTIC COMPOUND IS IMPREGNATED, AFTER WHICH THE IMPREGNATED CARRIER IS CALCINED.

Abstract: 1. A METHOD FOR THE PREPARATION OF A CATSLYST CARRIER WHICH COMPRISES: (I) PULVERZING A MEMBER SELECTED FROM THE GROUP CONSISTING OF A12O3, SIC AND ZRO2 INTO PARTICLES WHICH PASS THROUGH A TYLER STANDARD SEIVE HAVING A MESH OF 65 TO 325, (II) MIXING SAID PARTICLES WITH A BINDER WHICH COMPRISES: (A) 0.1 TO 2.8% BY WEIGHT OF STARCH PRODUCED BY PRE-TREATING A STARCH-CONTAINING RAW MATERIAL WITH AN ORGANIC OR INORGANIC ACID FOR 1 TO 3 DAYS AT ATMOSPHERIC PRESSURE UNTIL THE OUTER SKIN OF THE RAW MATERIAL AT A TEMPERATURE THE PRE-TREATED RAW MATERIAL AT A TEMPERATURE OF 100 TO 300* C. FOR 40 TO 80 MINUTES TO PRODUCE A LUMP OF STATCH, RESULTANT LUMP OF STARCH, (B) 0.05 TO 2.5% BY WEIGHT OF A MEMBER SELECTED FROM THE GROUP CONSISTING OF SODIUM CARBONATE, CALCIUM CHLORIDE AND MAGNESIUM SULFATE, AND (C) 0.05 TO 2.5% BY WEIGHT OF A MEMBER SELECTED FROM THE GROUP CONSISTING OF ALUMINUM CHLORIDE, SILICON CHLORIDE AND ZIRCONIUM CHLORIDE WITH THE PRIVISO THAT (1) THE TOTAL WEIGHT OF COMPONENTS A, B AND C DO NOT EXCEED 0.2 TO 3% OF THE PARTICLES OF STEP I, AND (2) THAT THE RATIO OF A A+B+C IS BETWEEN 0.38 AND 0.98, B A+B+C IS BETWEEN 0.017 AND 0.945 AND C A+B+C IS BETWEEN 0.017 AND 0.945; (III) MOLDING SAID MIXTURE INTO A PREDETERMINED SHAPE, AND (IV) CALCINING THE SPACED MIXTURE AT ABOUT 600* C. TO ABOUT 1350* C. FOR 1 TO 5 HOURS TO PREDUCE SAID CARRIER.

Abstract: THIS INVENTION RELATES TO A METHOD FOR THE PREPARATION OF A CATALYST USABLE FOR CATALYTIC CRACKING OF HYDROCARBONS, CHARACTERIZED BY THE STEPS OF (I) PULVERIZING A CARRIER MEMBER SELECTED FROM THE GROUP CONSISTING OF A-ALUMINA CONTAINING ABOVE 98% OF AL2O3, A MAGNESIUM CLINKER CONTAINING ABOVE 96% OF MGO AND BELOW 1% OF AN IRON OXIDE, SIC, ZRO2, ZON, THO2, M0O2 AND FE2O3 INTO PARTICLES PASSING THROUGH A TYLER STANDARD 65-MESH SIEVE, (II) MIXING THE PARTICLES WITH A NICKEL OXIDE IN AN AMOUNT OF 1 TO 30% BY WEIGHT AND A BINDER WHICH COMPRISES (A) 0.1 TO 2.8% BY WEIGHT OF STARCH TREATED WITH ACID UNTIL THE OUTER SKIN IS DESTROYED AND THEN HEATING AT 100* TO 300*C.; (B) 0.05 TO 2.5% BY WEIGHT OF A MEMBER SELECTED FROM THE GROUP CONSISTING OF ALKALI METAL CARBONATES AND PHOSPHATES, CALCIUM, MAGNESIUM AND AMMONIUM CARBONATES, CHLORIDES, FLUORIDES, SULFATES AND PHOSPHATES, ZINC AND IRON PHOSPHATES AND MIXTURES THEROF, AND (C) 0.05 TO 2.5% BY WEIGHT OF A MEMBER SELECTED FROM THE GROUP CONSISTING OF CHLORIDES AND PHOSPHATES OF THE MATERIAL OF STEP I WITH THE PROVISO THAT (1) THE TOTAL WEIGHT COMPONENTS A, B AND C DO NOT EXCEED 0.2 TO 3% OF THE PARTICLES OF STEP I, (2) THAT COMPONENTS B AND C BE DIFFERENT AND (3) THE RATIO OF A/A+B+C IS BETWEEN 0.38 AND 0.98, B.A+B+c IS BETWEEN 0.017 AND 0.945 AND C/A+b+c IS BETWEEN 0.17 AND 0.945; (III) MOLDING THE MIXTURE TO A SHAPED PRODUCT, DRYING THE SHAPED PRODUCT AND (IV) THEN CALCINING THE DRIED PRODUCT AT A TEMPERATURE OF ABOUT 1250*C. TO ABOUT 1350*C. TO PRODUCE THE CATALYST. ALTERNATIVELY, THE BINDER MAY BE CALCINED WITHOUT THE NICKEL OXIDE, SUBSEQUENTLY IMPREGNATED WITH NICKEL OXIDE AND CALCINED AGAIN.
