Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
59 words
A method for preparing a super active synthetic crystalline zeolite catalyst material of high hydrocarbon conversion activity having a constraint index between about 1/2 and 12 and a SiO 2 /Al 2 O 3 mole ratio greater than 7 which comprises contacting said zeolite with steam followed by base exchange of the resultant steamed product with an ammonium salt.
Claim 2
Independent Claim
59 words
A method for preparing a super active synthetic crystalline zeolite catalyst material of high hydrocarbon conversion activity having a constraint index between about 1/2 and 12 and a SiO 2 /Al 2 O 3 mole ratio greater than 7 which comprises contacting said zeolite with steam followed by base exchange of the resultant steamed product with an ammonium salt.
