Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
51 words
A DECATIONIZED ALUMINOSILICATE ZEOLITE MOLECULAR SIEVE HAVING A CRYSTALLINE STRUCTURE, A SILICON DIOXIDE TO ALUMINUM TRIOXIDE MOLAR RATIO GREATER THAN ABOUT 3.0, A PORE SIZE SUFFICIENT TO ABSORB BENZENE, AND A METAL-CATIONTO-ALUMINUM ATOMIC RATIO OF LESS THAN ABOUT 0.9, LESS THAN 90 PERCENT OF THE ALUMINUM ATOMS BEING ASSOCIATED WITH CATIONS.
Claim 2
Dependent Claim
51 words
A DECATIONIZED ALUMINOSILICATE ZEOLITE MOLECULAR SIEVE HAVING A CRYSTALLINE STRUCTURE, A SILICON DIOXIDE TO ALUMINUM TRIOXIDE MOLAR RATIO GREATER THAN ABOUT 3.0, A PORE SIZE SUFFICIENT TO ABSORB BENZENE, AND A METAL-CATIONTO-ALUMINUM ATOMIC RATIO OF LESS THAN ABOUT 0.9, LESS THAN 90 PERCENT OF THE ALUMINUM ATOMS BEING ASSOCIATED WITH CATIONS.
Claim 3
Dependent Claim
57 words
A PROCESS FOR THE PREPARATION OF A CRYSTALLINE DECATIONIZED ZEOLITIC ALUMINOSILICATE, WHICH COMPRISES ION-EXCHANGING A SUBSTANTIAL PORTION OF A METAL ALUMINOSILICATE ZEOLITE HAVING A SILICON DIOXIDE TO ALUMINUM TRIOXIDE RATIO OF GREATER THAN ABOUT 3.0 AND A PORE SIZE SUFFICIENT TO ADSORB BENZENE WITH AMMONIUM IONS, FOLLOWED BY THERMAL TREATMENT AT TEMPERATURES OF BETWEEN 350*C. AND 600*C.
