Molecular sieve for special use

 

Molecular sieve for special use

Chemical Formula:

Ca5Na2[(AlO2)12(SiO2)12]·XH2O
Introduction:
it is developed by Nanjing Heyi Chemical Col, LTD special for dewaxing.
Uses:
molecular sieve adsorbent special for dewaxing can separate liquid paraffin from branched alkane and cyclic hydrocarbons during the course of selective adsorption. Now, it is largely used to separate isoalkane and alkane in industry.
Packing:
sealed iron drum, 25kg, 50kg, 150kg.
