Process for the preparation of EUO-type zeolite using structuring agent precursors and use thereof as catalyst for isomerizing eight carbon aromatics

摘要

The synthesis of EUO zeolites is effected in the presence of organic structuring precursors which are less hazardous in use than the structuring agents themselves. The synthetic process involves the mixing, in aqueous solution, of a source of an element X (Si or Ge), a source of an element T, chosen from Al, Fe, Ga, B, Ti, V, Zr, Mo, As, Sb, Cr and Mn, and a monoamine precursor of a structuring agent comprising an alkylated derivative of polymethylene alpha , omega diammonium. Independent claims are also included for the EUO zeolite obtained by the process, and its uses.
