(A) Zeolite (''ECR-17'') has the compsn. - (aH, bCs)2O:Al2O3:xSiO2 (I), - where a = 0.6-1; b = 0-0.4; a + b = 1.0 +/- 0.05; x = 7 or more; and a specified CuK alpha X-ray diffraction pattern (d) (Angstrom, I/IO): where the 3 highest are 14.1-13.8, 100 +/- 20; 12.3-12.0, 15 +/- 10; and 8.7-8.47, 30 +/- 10. - (B) Hydrocarbon conversion catalyst comprises a zeolite defined as in (A). (C) Hydrocarbon conversion, pref. cracking, process comprises contacting a hydrocarbon with the catalyst of (B) under conversion conditions. - In formula (I), pref. x = about 8-2,000. The H, Cs and Na ions in the zeolite may be at least partly replaced by cations of metal(s) from Gps. I-VIII and NH4. The catalyst pref. also contains a matrix component, comprising Al2O3, clay or other inorganic oxide. ECR-17's structure seems to be very similar to that of CSZ-1 (US 4,309,313).
