<p>A novel crystalline zeolite composition is prepared by conducting the hydrothermal cystallization and, preferably, an aging step, at high pressure, i.e. pressures in excess of 40,000 psig (about 276 MPa(megaPascals)). The crystalline zeolite, designated as zeolite HP, has a structure similar to that of zeolite X but has a higher aluminum content then zeolite X and a lattice constant of above about 25.02 A.</p> |
