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 4.40A 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 A0 from fluids by using the surface modified adsorbents.
