A molecular sieve blend containing a zeolite, particularly a zeolite X or A, blended with a halloysite clay binder, wherein the binder contains at least 90% by weight halloysite clay, with a particle length less than about 1 &#x3bc;m and processes for the production and use of this blend, particularly for adsorption of water from a feedstream and for the production of oxygen.

Zeolite agglomerates with a halloysite clay binder

A molecular sieve blend with improved performance characteristics produced by preparing or obtaining a hydrophilic zeolite, particularly a hydrophilic zeolite A with a low SiO:AlOratio, preparing or obtaining a hydrophobic silicon based binder, particularly a hydrophobic colloidal silica or a hydrophobic siloxane based material, mixing the zeolite with the silicon based binder and, in one embodiment, a seed containing small quantities of a clay binding agent and the zeolite, to form a mixture, and forming the mixture into the molecular sieve blend.

Molecular sieve adsorbent blends and uses thereof

A process for the production of a molecular sieve blend with improved performance characteristics produced by preparing or obtaining a hydrophilic zeolite, particularly a hydrophilic zeolite A with a low SiO:AlOratio, preparing or obtaining a hydrophobic silicon based binder, particularly a hydrophobic colloidal silica or a hydrophobic siloxane based material, mixing the zeolite with the silicon based binder and, in one embodiment, a seed containing small quantities of a clay binding agent and the zeolite, to form a mixture, and forming the mixture into the molecular sieve blend.

A process for the production and use of a molecular sieve blend with improved performance characteristics produced by preparing or obtaining a hydrophilic zeolite, particularly a hydrophilic zeolite 3A with a low SiO:AlOratio, preparing or obtaining a hydrophobic silica binder, particularly a hydrophobic colloidal silica, mixing the zeolite with the silica binder to form a mixture, and forming the mixture into the molecular sieve blend.

A lithium exchanged zeolite X adsorbent blend with improved performance characteristics produced by preparing a zeolite X, preparing a binder which includes highly dispersed attapulgite fibers wherein the tapped bulk density of the highly dispersed attapulgite fibers measured according to DIN/ISO 787 is more than about 550 g/ml, mixing the zeolite X with the binder to form a mixture, forming the mixture into a shaped material, ion exchanging the zeolite X at least 75% with lithium ions, and calcining the shaped material.

Lithium exchanged zeolite X adsorbent blends

A Process for the production and uses 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.

Process for use of molecular sieve adsorbent blends

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.

Process for production of molecular sieve adsorbent blends

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.
