Improved adsorptive purification process. |
摘要 |
<p>A vapor phase purification process using a fixed adsorbent bed containing a zeolitic molecular sieve comprising zeolite crystals having the faujasite crystal structure and containing cations having a higher charge density than sodium cations, whereby regeneration of the bed is accomplished using purge gas streams at temperatures of from 55 DEG C. to 100 DEG C. The ability of the zeolite adsorbent to be regenerated at relatively very low temperatures permits the use of heat energy normally to low in intensity to be utilized and is thus usually waste energy.</p> |
