AI summary

Disclosed invention relates to a zeolite coating preparation assembly and method for using the same, where a cylindrically designed metal substrate (7) and induction coil (5) as well as a preferably cylindrical reactor (4) are utilized. The substrate is heated by induction and the synthesis solution is circulated in system between the reactor and a heat exchanger (10) for keeping the synthesis solution temperature at a value below the heated substrate. Wire meshes, porous and non- porous metals of cylindrical shape are used as substrates. These substrates may also have welded and multi-layered architecture. Relatively thick, more uniform and durable coatings are reproducibly, economically and practically prepared in short times and large surfaces. Reproducible preparation of continuous and thin coatings usable as membranes is made possible, with short synthesis times and a non-contact manner distance heating.
