Abstract

Provided is a method of producing a zeolite film continuously and efficiently. Zeolite is formed on a surface of a support using a method including: a first step of attaching zeolite fine crystals to a surface of a support; a second step of preparing synthetic gel for growing the fine crystals; a third step of putting the support and the synthetic gel into a reactor and performing hydrothermal synthesis; and a fourth step of cleaning the support subjected to the hydrothermal synthesis, in which in the third step, multiple containers arranged to be movable in a constant-temperature apparatus are each used as the reactor, the temperature and pressure for the hydrothermal synthesis is adjusted by the temperature and pressure in the constant-temperature apparatus, and the reaction time of the hydrothermal synthesis is adjusted by setting the time from when the reactor enters the constant-temperature apparatus to when the reactor exits the constant-temperature apparatus.
