zeolite process
3.HAY-Ⅰ and HAY-Ⅱ, which were two new types of ultra-stable Y zeolite with homogeneous aluminium distribution verified by XPS, were prepared by further acid leaching of zeolite USY and treatment of NH4Y zeolite by improved framework-silicon-enriched process with fluorosili-cate solution respectively.
5.Green Chemistry and Chemical Process-Fries Rearrangement of Phenyl Acetate(PA) over Y Zeolite Catalyst
8.A process for regenerating adsorbent 13X zeolite during purification of recycle paraffins was developed, wherein a light normal paraffin WV and a aromatics DV were respectively selected as flushing material and desorbing material at column temperature of 80,150℃ and space velocity of 2.25, 1.5h-1 for flushing and desorbing process separately.
