An apparatus containing a multilayered zeolite-adsorbent bed and a process for separating oxygen from air by the adsorption of at least nitrogen by the bed are described. The multiple layers of adsorbent are NaX zeolite followed by at least another layer of adsorbent selected from CaX zeolite, LiX zeolite, CaA zeolite followed by CaX zeolite, CaA zeolite followed by LiX zeolite, CaX zeolite followed by LiX zeolite, LiX zeolite followed by CaX zeolite, and MgA zeolite followed by CaX zeolite.

Nov. 18, 1994 A process is disclosed for selectively adsorbing nitrogen from another less strongly adsorbed gas (particularly oxygen), involving contacting the gas mixture in an adsorption zone with an adsorbent consisting of a large-pored molecular sieve containing at least one octahedral site comprising titanium and at least silicon as a tetrahedral site. The process is particularly useful in air separation using ETS-10 as the adsorbent.

High bulk density (20.5 g/cmd3) granular detergent compositions with excellent solubility are manufactured by spray drying and granulation of a slurry of a-sulfofatty ester salts (l-15%), alkylbenzenesulfonates, u-olefinsulfonates, or alkyl sulfates (325%), carbonates (20-45%), and bicarbonates (0.5-8%). or by neutralization of linear alkylbenzenesulfonates with carbonate salts and optionally alkali metal hydroxides, adding u-sulfofatty acid ester and zeolite-containing (lo-25% zeolite) detergents to the resulting salts, and spray drying and granulation.

Highly active granular detergent compositions having 240% surfactant and a bulk density 2650 g/l are obtained by a process involving the single step of higher shear mixing until granular at a temperature range from ambient to 60°C of a binder component (the surfactant and ~20% water), with a crystalline zeolite of initial particle size 0.1 to about 500 km (having 215% of particles with a size of 250 +m and a sufficient amount of smaller particles so that the average surface area of the zeolite is 29 m2/g as measured by the BET method). The binder maintains the mixture in a particulate state throughout the process.

the content of fatty acid and fatty alcohol is preferably 9-12% and the ratio of fatty acid to fatty alcohol is preferably 0.91.05:1. Preferably, the builder is a water-insoluble zeolite, the fatty acid is stearic acid, and the fatty alcohol is cetyl alcohol. The surfactant mixture enhances the dispensability of the composition for use in washing machines with side-flush dispensers.
