Abstract: A process for the production of a molecular sieve adsorbent blend product with improved performance characteristics produced by preparing a zeolite powder, preparing a highly dispersed attapulgite fiber binder, mixing the zeolite powder with the highly dispersed attapulgite binder to form a mixture, forming molecular sieve adsorbent products into a shaped material and calcining the shaped material, wherein the tapped bulk density of the highly dispersed attapulgite fibers measured according to DIN/ISO 787 is more than about 550 g/ml.

Abstract: 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 &mgr;m, 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.

Abstract: An adsorbent for organic sulfur compound removal from mineral, vegetable or animal oils useful to protect a hydrogenation catalyst against poisoning, wherein the adsorbent is a zinc-exchanged form of low silica faujasite with a silica to alumina ratio from about 1.8 to about 2.1, wherein the adsorbent contains an inequivalent excess of zinc cations from about 8 to about 20% (equiv.) and a process for manufacture and use of the adsorbent.
