METHOD FOR PREPARING ZEOLITES, ZEOLITES OBTAINED BY SUCH METHOD AND THEIR USE FOR THE CONVERSION OF HYDROCARBONS |
摘要 |
Preparation of zeolites having the formula: (1.5 +/- 0.6)M2/nO.Al2O3.Y SiO2. Z H2O wherein Y ranges from 20 to 90, Z ranges from 2 to 12, M is at least one cation and n ist the valence of M; said preparation comprises the admixing of diethyl-piperidinium hydroxide [(DEPP)<+>OH<->] or of a salt thereof with water and with: a) at least one sodium compound; b) at least one compound of aluminium; c) at least one compound of silicon; the respective molar ratios, expressed as ratios of oxides, being comprised in the following ranges: SiO2:Al2O3 = from 20 to 120 Na2O:SiO2 = from 0.07 to 0.50 (DEPP)2O:SiO2 = from 0.05 to 0.50 H2O:Na2O = from 50 to 600. The invention concerns also zeolites obtained by said preparation and their use for some acid-catalyzed conversions of hydrocarbons. |
