Abstract: A zeolite catalyst and a method for reduction of nitrogen oxides present in waste gas streams is described. The method includes mixing the waste gas containing nitrogen oxides with ammonia. At an elevated temperature, this mixture is passed over a zeolite catalyst. Preferably, the zeolite catalyst is in a monolithic or honeycomb form. The zeolite catalyst includes one or more of the following subgroup metals: copper, iron, molybdeum and cerium. The zeolite catalysts made in accordance with this invention show better conversion of nitrogen oxides and longer life than known catalysts.

Abstract: Templating compounds of the formula: (HO-C2H4)3N(+)-(CH2)n-N(+)(C2H4-OH)3 2 Br(-) wherein n equals 3, 4 or 5 are produced by reacting triethanolamine with alpha , omega dibromoalkanes, for example in the presence of a solvent. One can also react dibromoalkane with the triethanolamine in dropwise manner at reaction temperature. The product is subsequently recovered by known methods. The templating compositions can be used for the preparation of the zeolites of the pentasil types. These zeolites have the composition represented by the summary formula: (0.4-0.7)Na2O/(0.3-0.6)Q2O/Al2O3/(30-80)SiO2/(4-10)H2O and have the following X-ray diffraction pattern: -d ANGSTROM I/Io -11.0 +/- 0.2 30-70 -10.0 +/- 0.2 30-80 -4.4 +/- 0.1 10-20 -4.3 +/- 0.1 10-20 -3.85 +/- 0.05 100 -3.74 +/- 0.05 40-65 -3.66 +/- 0.05 20-40 -3.43 +/- 0.03 15-25 -2.01 +/- 0.02 5-15 -1.99 +/- 0.02 5-15 - They are prepared by utilizing an aqueous suspension of precipitated silica and mixing with an aqueous sodium aluminate composition and an aqueous solution of the template compound. This mixture is then converted under autogeneous pressure, the product is dried and then calcined. The pentasil type zeolites can be used in the conversion of methanol into hydrocarbons.

Abstract: The crystalline aluminosilicate PZ 1 is produced by carrying out the crystalline in the presence of an organic template compound of the formula R3P-(CH2)n-PR3X2 where R is a lower alkyl group, n is an integer of 2 to 6 and X is Br- or I-. The synthesis mixture has the composition: -SiO2/Al2O3 = 20-250 -Na2O/SiO2 = 0.01-0.5 -OH/SiO2 = 0.01-1.0 -T/SiO2 = 0.01-0.2 -H2O/SiO2 = 10-40 - whereas T means template compound. The synthesis mixture is stirred at a temperature between 90 DEG and 200 DEG C. at autogenous pressure. The aluminosilicate PZ 1 is changed into the aluminosilicate PZ 2 by treatment with dilute acids or with ammonium chloride and subsequent calcining. This aluminosilicate PZ 2 can be employed as catalyst in the conversion of alcohols into hydrocarbons.
