    摘要: The present disclosure comprises a new method for hydrothermal synthesis of ferrierite zeolite, using tetramethylammonium and benzylmethylpyrrodlidine as directional structure agents, and does not require a subsequent process in order to obtain the acid form of the material. This aspect is very important as it avoids subject treatments of calcination and successive interchanges which degrade the structure of the zeolite. The synthetic ferrierite obtained by means disclosed processes has uses in catalytic processes of transformation of hydrocarbons, such as cracking, isomerization, alkylation, and polymerization. Specifically, it can be used in the isomerization of butene to isobutene. To be used in catalytic processes, the zeolite ferrierite must be heated in an oxidant atmosphere in conditions such that the organic material occluded in the interior is eliminated.

    摘要: An improved process is disclosed for producing alumino-silicates having a porous structure, of the zeolite class, the process essentially comprising the step of preparing a homogeneous aqueous mixture containing a source of alumina, a source of silica and alkali metal bases and/or alkaline earth metal bases, the improvement consisting in adding to said mixture at least one substance which contains at least a hydroxyl group in its molecule. The advantages are that the use of nitrogenous organic substances, universally used heretofore for the preparation of certain zeolites, can be dispensed with inasmuch as the alkali metal ion is capable, alone, of displaying the counter-ion function.

    摘要: Crystalline aluminosilicate molecular sieves are prepared by (1) forming an aqueous mixture of an oxide of aluminum, an oxide of silicon, a metal or ammonium cation and a suitable oxygen-containing monomeric organic template compound, (2) maintaining the pH of such mixture between 9 and 14, and (3) crystallizing the mixture. The organic templates include ethanolamine, diethanolamine, triethanolamine, ethylethanolamine, ethyldiethanolamine, 2-amino-2-ethyl-1,3-propanediol, morpholine, and alkali metal complexed tetrahydrofuran, dioxane, dioxolane, and crown ethers. Crystalline aluminosilicates prepared include mordenite, ferrierite, ZSM-4, and ZSM-5.
