Patent report The title method involves contacting C2-7 aliphatic and/or alicyclic hydrocarbon(s) with an acid-type crystalline galiosilicate that contains PT and is prepared from a mixture of Ga, Pt, and Si compounds. The above catalyst is also described.
SEPARATION PROCESSES Zeolite adsorbent for vapors from fuels containing alcohols
The title compositions showing optimum bleach activator performance contain nonionic surfactant 8-35, zeolite 4A 20-60, a peroxide generating H202 in water 5-20, an organic peracid precursor that generates quaternary ammonium group-containing organic peracid upon reaction with H202 1-10, and a copolymer having -CH(COOM)CH(COOM)- unit (M = H, alkali metal, alkaline earth metal, ammonium) 1-5%, with phosphate salt content being < 0.1%.

May 19, 1989 An alcohol-free beer is prepared from a normally brewed beer by adsorption of EtOH onto a (NaZSM-5, Si/AI -- 50) zeolite bound with a cellulose derivative. The pore size is large enough to admit EtOH but not molecules responsible for the flavor of the beer. The EtOH-saturated adsorbent can be regenerated by thermal desorption.

Oct. 24, 1990 The particulate desiccant for air conditioning systems comprises a modified aluminosilicate (e.g., zeolite 13Y, zeolite NaY, erionite) having an isotherm separation factor of 0.07-0.1, a SIO2/AI203 ratio of >~3:1, and a pore diameter of 4-10 A. To reduce the polarity on the inner surfaces, the aluminosilicate is treated with an aqueous acid or ammonium solution (e.g., NH4CI) for exchange of metal ions with protons and removal of a portion of the AI. The acid can be EDTA or HCi. C h r y s o z e o l i t e soil amendments R.L. Van Mao U.S. 5,082,488, Jan. 21, 1992; Appl.

Tomei Sangyo K.K. Jpn Kokai Tokkyo Koho 91,275,063, Dec. 5, 1991; Appl. Mar. 24, 1990 Contact lenses are sterilized by H202 and subsequently the residual H202 is decomposed by Cu (OH)2 and/or Cu complex ion bound to zeolites. After sterilization of the lens by H202, the residual H202 is rapidly decomposed by Cu2+. Thus, a soft contact lens and Cu(OH)2bound zeolite were added to a HzO2 solution. The lens was sterilized and the residual H202 degraded by Cu2+ in the same solution.
