A SURFACE MODIFIED ZEOLITE FOR DRYING REFRIGERANTS

摘要

The present disclosure relates to a surface modified zeolite having formed pores therein, with apertures on the surface of the zeolite of diameter less than 4.4° A without reduction of the pore volume. The present disclosure also relates to a process for the preparation of the surface modified zeolite and a method of selectively removing substances with molecular size below 4.4 A° from fluids by using the surface modified adsorbents.
