    摘要： Magnesium-silicate bound zeolite granulates of type A are disclosed wherein the zeolite component does not contain magnesium exclusively, or contains no magnesium at all, as the cation. The granulates are produced by placing powdered zeolite A in a mixer, adding sodium silicate solution, mixing until zeolite granulates with a grain size of at least 0.1 mm are obtained, optionally after-rolling these zeolite granulates, optionally initially drying the moist zeolite granulates at temperatures of 20 to 39 degrees C., during which the carbon dioxide content of the drying air is adjusted to less than 200 ppm, then optionally drying in a second drying step at temperatures of 40-120 degrees C. and optionally in a third drying stage at 121-200 degrees C. under otherwise identical conditions, and then optionally activating the granulates thus obtained at temperatures of 600 degrees C. maximum. The granulates thus obtained are treated with an aqueous magnesium salt solution, washed, then optionally treated with aqueous metal salt solution, washed, dried at 40-200 degrees C., preferably 100 to 120 degrees C., and then optionally calcined at 300 to 650 degrees C.

    摘要： A seed mixture is produced by reacting an amorphous, synthetic sodium aluminum silicate with an Na.sub.2 O-supplying compound in an aqueous system at temperatures of 10.degree. to 35.degree. C. (room temperature). The seed mixture exhibits a composition of Na.sub.2 O:Al.sub.2 O.sub.3 :SiO.sub.2 :H.sub.2 O=(12.+-.3):1:(15.+-.3):(240.+-.60). This seed mixture can be used in the synthesis of zeolite Y and/or zeolite X.

    摘要： In order to be independent of the situation in regard to methane and natural gas and at the same time to obtain a heating gas there is employed in the hydrocyanic acid-methane-ammonia process (the BMA process) in place of methane an alkanol or alkanediol having 2-4 carbon atoms, preferably ethyl alcohol, and this is reacted with ammonia in a C:N ratio of 0.8:1 to 2:1. Optionally additional hydrogen can be present.
