A molecular sieve adsorbent for the purification of gas streams containing water vapor and carbon dioxide. The adsorbent is a combination of sodium form of a low-silica faujasite, having a residual content of potassium ions less than about 8.0 percent (equiv.), a low content of crystalline and amorphous admixtures and crystal sizes generally within the range of 1-4 mum, and a binder. A process for the adsorbent preparation which comprises specific parameters of low silica faujasite synthesis, sodium-potassium ion exchange, blending and granulation.
