Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
112 words
A HYDROCARBON CONVERSION CATALYST COMPRISING AS ESSENTIAL COMPONENTS A MINOR PROPORTION OF A TRANSITIONAL METAL HYDROGENATION COMPONENT INTIMATELY DISTRIBUTED ON A MAJOR PROPORTION OF A CRYSTALLINE, ZEOLITIC, ALUMINO-SILICATE BASE, SAID ALUMINO-SILICATE BASE HAVING BEEN PREPARED BY DIGESTING A CRYSTALLINE ALUMINO-SILICATE ZEOLITE HAVING A SIO2/AL2O3 MOLE-RATIO BETWEEN ABOUT 6AND 12 AND CRYSTAL PORE DIAMETERS IN THE RANGE OF ABOUT 3-8 A. WITH AN AQUEOUS CAUSTIC SOLUTION COMPRISING ESSENTIALLY AN ALKALI METAL HYDROXIDE, SAID SOLUTION HAVING A PH ABOVE ABOUT 10.5, FOR A SUFFICIENT LENGTH OF TIME TO LEACH OUT BETWEEN ABOUT 0.5% AND 40% OF THE STRUCTURAL SILICA CONTENT THEREOF BUT WITHOUT DESTROYING THE ORIGINAL CRYSTAL STRUCTURE THEREOF, FOLLOWED BY WASHING AND DRYING.
