Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
108 words
THE PROCESS OF PREPARING RUGGED COMPOSITE CATALYST BODIES CONTAINING PRINCIPALLY SILICA AND ALUMINUM PHOSPHATE WHCIH COMPRISES FORMING A DILUTE AQUEOUS ALKALINE SOLUTION OF AN ALKALI METAL SILICATE, AN ALKALI METAL ALUMINATE, AND PHOSPHORIC ACID; ADJUSTING THE PH OF SAID SOLUTION SO AS TO PRECIPITATE A POROUS GEL CONTAINING SILICA AND ALUMINUM PHOSPHATE; WASHING SAID GEL TO REMOVE ALKALI METAL SALT; DRYING SAID GEL; FORMING THE DRIED GEL INTO SMALL BODIES OF SUITABLE SHAPE FOR CATALYTIC PROCESSES BY COMPRESSING SAME AT AN ELEVATED PRESSURE; AND CALCINING SAID BODIES AT A TEMPERATURE IN THE RANGE OF 250 TO 800*C. FOR AT LEAST SEVERAL HOURS TO FORM HARD, ATTRITION-RESISTANT CATALYST BODIES.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
87 words
THE PROCESS OF CONVERTING A FEED CONSISTING ESSENTIALLY OF C3 TO C24 OLEFIN HYDROCARBON TO OTHER HYDROCARBON MATERIAL WHICH COMPRISES CONTACTING SAID HYDROCARBON UNDER CONVERSIONS INCLUDING A TEMPERATURE IN THE RANGE OF 10 TO 450*C. WITH A CATALYST IN THE FORM OF HARD, ATTRITION-RESISTANT, POROUS BODIES OF PRECIPITATED SILICA GEL HAVING ALUMINUM PHOSPHATE INCORPORATED IN ITS MATRIX DURING PRECIPATION, THE CONCENTRATION OF ALUMINUM PHOSPHATE IN SAID BODIES BEING IN THE RANGE OF 1 TO 25 WEIGHT PERCENT, SO AS TO CONVERT SAID HYDROCARBON TO OTHER HYDROCARBON MATERIAL.
