Patent report Z e o l i t e molecular sieve adsorbent for separation of compositions having molecular diameters o f a few ang-
stroms in narrow size range J. Horii
Kobe Steel, Ltd. Jpn. Kokai Tokkyo Koho 92,219,135, Aug. 10, 1992; Appl. Dec. 19, 1990 The adsorbent is an A-type zeolite of formula M12~n [(AIO2)12(SiO2)12].xH20 where M = metal ions, n = valence of the metal ions, x = 0-27. Mixed Na and Li ions are present at 55-75 or preferably 65-70 mol. %. The zeolite can be used for separation of EtOH from MeOH, etc.

Taiyuan Polytechnical University Chinese 1,061,577, June 3, 1992; Appl. Nov. 17, 1990 H storage materials are zeolite-alloy inclusion compounds (e.g., mordenite zeolite-TiFeo.gsCro.os), and are prepared by grinding the alloy to 0.1 microns-0.1 ram, mixing with aluminosilicate particles, and arranging the mixture on the top of a perforated plate in an autoclave with water on the bottom of the autoclave for crystallizing.

PCT Int. Appl. 92,13,899, Aug. 20, 1992; SE Appl. Feb. 7, 1991 The title process useful for removing odour- and taste-producing subtances consists of adding 10-1000 ppm zeolites to the reactor. Thus, polyetbylene, prepared in the presence of Cr catalyst and 292 ppm hydrophobic zeolite, had low value of taste/odor level.
The title compound (I) is separated from a hydrocarbon oil containing t> 5% I and ~> 30 % dimethylnaphthalenes by adsorption on HY zeolites with silica/alumina I>3 (mol).

Process for molecular alignment in the orientation o f molecular sieve c r y s t a l s J. Caro; B. Zibrowius; G. Finger et al. Ger. Often. 4,109,037, Sept. 17, 1992; Appl. Mar. 15, 1991
DETERGENTS
In the title process, in which a multitude of small crystals can simulate a single crystal, molecular compounds are adsorbed or formed in the pore systems of molecular sieve crystals. The crystals are oriented on capacitor plates at field strength 1-10 V/mm with respect to their crystallographic axes, and the oriented crystals can be embedded in a curable matrix, which is then cured, orthe unfixed crystals can be aligned in other directions by later application of an electric field. C2H2 was polymerised in the pores (diam. 7.3 A) of AIPO4 crystals. The crystals were oriented on the lower 2 parallel capacitor plates separated by 2 cm. at a field of 80.2 kV/mm, and the aligned crystals were embedded in a mobile expoxy resin, which was then cured.

02 containing N2 is fed into an adsorption column packed with A-type zeolite containing Li + and Na + (55-75 mol % Li + based on both ions) at temperatures below -50°C to remove 02. Purified liquefied N2 is used as coolant for the adsorption column. High purity (99.999 vol. %) N2 can be obtained.
Kao Corp. Jpn. Kokai Tokkyo Koho 92,306,299, Oct. 29, 1992; Appl. Apr. 3, 1991 The title compounds with good water solubility, useful in washing machines, comprise nonionic surfactants with m.p. ~<90°C and HLB 7.5-17.0, crystalline aluminosilicate salts (e.g., zeolite 4A), and porous oil adsorbents with dispersion pH of ~>9.

The title membranes, with controlled pore size (2-20 A) and good thermal, chemical, and mechanical stability, are prepared by orienting molecular sieve crystals in a fluid with their long axis parallel to a capacitor field at field strength 1-10,000 V/mm, fixing the oriented crystals in a thin, curable, organic or inorganic layer, and embedding the fixed crystals in a curable matrix. Crystals of aluminophosphate molecular sieve (AFI structure) were oriented on the lower of two parallel capacitor plates at a capacitor field of 0.2 kV/mm, covered with a thin layer of epoxy resin, and abraded to free the pores of the molecular sieve, giving a membrane with pore diameter 7.3 A.
