In this process, the outlet gaseous product is a<br /> combination of ethylene, ethane and hydrogen. Effective separation techniques<br /> are required for separation of ethylene from unreacted ethane. Here a new<br /> adsorbent approach is introduced for separation of ethylene from ethane. The<br /> adsorbent is a kind of zeolite- like molecular sieve from<br /> silico-alumino-phosphate group (SAPO-34) which is previously synthesized and<br /> studied in the adsorption tests of ethane and ethylene. The equilibrium<br /> adsorption experiments are performed in a static batch adsorption apparatus at<br /> various moderate pressures and room temperature to evaluate the adsorption<br /> capacity and selectivity toward ethylene against ethane. A high tendency of<br /> SAPO-34 towards ethylene and the ethylene/ethane selectivity from 2 to 3 fold<br /> in the pressure range of 200 to 800 kPa is observed, confirming the potential<br /> application of SAPO-34 as an adsorbent in the adsorption process for separation<br /> of ethylene and ethane.  https://gpj.ui.ac.ir/article_20170_eb7137f9c9b71eaede32deb0dab4e056.pdf
