FAUJASITE ZEOLITIC MATERIALS

摘要

Novel crystalline zeolitic materials of the faujasite structure having an increased ratio of zeolitic surface area to mesoporous surface area and distinctive X-Ray Diffraction peak ratios are produced by calcining zeolite Y of low sodium content at temperatures above 600 DEG C. The zeolites are useful catalysts for effecting hydrocarbon conversions including cracking and hydrocracking.
