--34 PROCESS FOR THE DIRECT SYNTHESIS OF CU-SAPO-34

摘要

A method for the direct synthesis of Cu-SAPO-34 comprising the steps of: water, at least one silicon source, at least one Al source, at least one P source, at least one Cu source, at least one OSDA1 (OSDA1 is any polyamine) And at least one OSDA2 (OSDA2 is any organic molecule capable of directing the synthesis of SAPO-34), wherein the final synthesis mixture comprises the following molar composition: a Si: 0.5 Al: b P: c Cu: d OSDA1: e OSDA2: f H₂0, where a ranges from 0.01 to 0.3; Where b ranges from 0.2 to 0.49; Where c ranges from 0.001 to 0.6; Where d ranges from 0.001 to 0.6; Where e ranges from 0.001 to 2; Where f ranges from 1 to 200; A hydrothermal treatment step of the mixture at 80-200 DEG C until the crystalline material is formed, and a step of recovering the crystalline material.
