ZEOLITE-CONTAINING CATALYST, PROCESS FOR PRODUCING THE ZEOLITE-CONTAINING CATALYST, AND PROCESS FOR PRODUCING PROPYLENE

摘要

THE PRESENT INVENTION PROVIDES A ZEOLITE-CONTAINING CATALYST HAVING EXCELLENT SHAPE, FLUIDITY AND MECHANICAL STRENGTH AS A CATALYST FOR A FLUIDIZED BED REACTION. THE PRESENT INVENTION PROVIDES A ZEOLITE-CONTAINING CATALYST WHICH IS A PARTICULATE CATALYST CONTAINING ZEOLITE AND SILICA, WHEREIN THE CATALYST HAS AN AVERAGE PARTICLE DIAMETER OF 20 TO 300 ?M AND THE RATIO OF THE VOID AREA IN THE CROSS-SECTION OF THE PARTICLE IS 30% OR LESS RELATIVE TO THE CROSS-SECTION AREA OF THE PARTICLE.
