Process for the preparation of a thin zeolite membrane |
| abstract |
Described is a process for the preparation of a supported zeolite membrane that consists of a zeolite/substrate composite layer, whose zeolite phase exhibits a crystallinity of at least 85%, comprising: n a) the formation of a gel or a solution that comprises at least one source of silica and water, supplemented with at least one polar organic compound, n b) bringing into contact said gel or said solution with a porous substrate, n c) the crystallization of the zeolite starting from said gel or said solution; and n d) the elimination of residual agents. n The molar ratio of the water to the silica in the gel or the solution in stage a) is between 27:1 and 35:1. The crystallization time of stage c) is at least 25 hours. n Said process is particularly suited for the preparation of zeolite membranes whose zeolite phase is of the MFI-structural type. |
