Abstract
Preparation of zeolites having the formula: EQU (1.5.+-.0.6) M.sub.2/n O.Al.sub.2 O.sub.3.ySiO.sub.2.zH.sub.2 O [wherein y ranges from 20 to 90, z ranges from 2 to 12, M is at least one cation and n is the valence of M], comprising the admixing of diethyl-piperidinium hydroxide, or a salt thereof, with H.sub.2 O and with at least one Na compound, one Al compound and one Si compound, the molar ratios (ratios of oxides) being: PA0 SiO.sub.2 :Al.sub.2 O.sub.3 =from 20 to 120; PA0 H.sub.2 O:Na.sub.2 O=from 50 to 600; PA0 Na.sub.2 O:SiO.sub.2 =from 0.07 to 0.50; PA0 (DEPP).sub.2 O:SiO.sub.2 =from 0.05 to 0.50. The invention concerns also the thus obtained zeolites and their use for acid-catalyzed conversions of hydrocarbons.
