摘要： HYDROCARBON CONVERSION CATALYSTS OF IMPROVED ACTIVITY ARE OBTAINED BY ACTIVATING FORMAMINOUS REFRACTORY OXIDES COMBINED WITH AT LEAST ONE THERMALLY DECOMPOSABLE AND/ OR OXIDIZABLE COMPOUND OF A CATALYTICALLY ACTIVE METAL UPON CALCINATION WHILE CONTACTING THE COMPOSITE WITH AN ACCELERATED FLOW OF AN OXIDIZING GAS AT A RATE OF AT LEAST ABOUT 2 S.C.F.M. PER POUND OF SAID COMPOSITE. FURTHER ADVANTAGE IS REALIZED BY HEATING THE COMPOSITE TO THE PRESCRIBED CALCINATION TEMPERATURE AT A CONTROLLED GRADUAL RATE. IT IS ALSO GENERALLY DESIRABLE TO ASSURE THAT THE INLET TEMPERATURE OF THE OXIDIZING GAS PRIOR TO CONTACT WITH THE COMPOSITE IS LESS THAN ABOUT 500*F.

摘要： INORGANIC OXIDE CATALYST SUPPORTES ARE COATED WITH CATALYTICALLY ACTIVE METALS BY A PROCESS WHICH INVOLVES FIRST FORMING A SEMI-CONDUCTIVE COATING OF CARBON ON THE SUBSTRATE AND THEN CONTACTING THE COATED SUBSTRATE WITH A SOLUTION OF THE CATALYTICALLY ACTIVE METAL IONS UNDER ELEC TROLYSIS CONDITIOND. THE CATALYTICALLY ACTIVE METAL DEPOSITS ON THE SURFACE OF THE CARBON COATED SURFACE IN A THIN, UNIFORM LAYER. THE CARBON MAY THEN BE REMOVED BY CONVENTIONAL OXIDATION TECHNIQUES.

摘要： A METHOD OF PREPARING A CATALYST OF VANADIUM-TITANIUM OXIDES FOR VAPOR-PHASE OXIDATION AND OXIDIZING AMMONOLYSIS OF AROMATIC AND HETEROCYCLIC COMPOUNDS COMPRISING PREPARING A POWDERY MIXTURE OF VANADIUM PENTOXIDE AND TITANIUM DIOXIDE WITH THE MOLE RATIO OF 1:0.6-32, RESPECTIVELY. THE AFORESAID MIXTURE IS PRESSES INTO TABLETS AND THEN EXPOSED TO HEAT TREATMENT IN AIR AT A TEMPERATURE OF FROM 650* C. TO 1000* C. SAID METHOD IS TECHNOLOGICALLY SIMPLE AND MAKES IT POSSIBLE TO OBTAIN A CATALYST FEATURING HIGH ACTIVITY AND SELECTIVELY AS WELL AS HIGH MECHANICAL STRENGTH AND THERMAL STABILITY.

摘要： A POROUS CATALYST BASED OR USPPORTED MATERIAL, FOR EXAMPLE ALUMINA, IS INITIALLY SATURATED WITH A POLYMERIZABLE HYDROCARBON, FOR EXAMPLE STYRENE, WHICH IS THEREAFTER POLYMERIZED. SUBSEQUENT IMPREGNATED SUPPORT IS SUBSEQUENTLY WITH CATALYTIC MATERIALS IS THUS RESITRICTED TO THE PERIPHERAL SURFACE THEREOF. THE IMPREGNATED SUPPORT IS SUBSEQUENTLY CALCINED WHEREBY THE HYDROCARBON POLYMER IS DEPOLYMERIZED AND SEPARATED THEREFROM.

摘要： AN IMPROVED CATALYST FOR OXIDATION OF HYDROCARBONS AND CARBON MONOXIDE IS PREPARED BY DEPOSITING AN AN ALUMINA SUPPORT LAYERS OF OXIDES OF COPPER, CERIUM AND CHROMIUM. ENHANCED CATALYST ACTIVITY IS OBTAINED WHEN CERIUM OXIDE IS APPLIED AS THE MIDDLE LAYER. CATALYTIC ACTIVITY IS FURTHER ENHANCED BY APPLYING THE COPPER OXIDE LAYER FIRST AND MAINTAINING THE MOLAR RATIO OF COPPER TO CHROMIUM GREATER THAN ONE.
