摘要： This invention describes a general process in which, by means of the use of tensioactives, it permits a reduction of the synthesis times for crystalline microporous materials based on silica with ducts with a pore opening formed of 10 or 12 tetrahedra of silica. This procedure is based on the addition of a tensioactive, which can be cationic, anionic or neutral, to the reaction mixture wherein the zeolite is formed. In addition, this new synthesis method increases the efficiency of the reagents used in the synthesis of zeolites and the stability of the materials formed, permitting the size of crystal to be controlled. And in cases wherein there exists competition for the growth of different microporous materials, it is possible to promote the appearance of one phase with respect to another competing with it by a proper selection of surfactant.

摘要： Ferrierite is prepared by a method that provides extremely pure crystalline material. The method consists of preparing a mixture of silica, alumina, alkali metal and pyridine of a certain composition and heating said mixture to form the crystals. The SiO.sub.2 /Al.sub.2 O.sub.3 and OH.sup.- /SiO.sub.2 are controlled to insure preparation of high SiO.sub.2 /Al.sub.2 O.sub.3 ratio, high surface area and high purity ferrierite. An improved olefin skeletal isomerization catalyst is prepared from a high silica to alumina ratio, high surface area and high purity ferrierite.
