Abstract
A process for manufacturing a zeolite membrane by hydrothermal synthesis on the surface of a porous tubular supportwith both ends open, by adding a reaction solution containing a silica source and an alumina source and the porous tubular supportinto a lengthwise reaction containerlonger than the porous tubular supportwhile placing the porous tubular supportvertically in the reaction containerand substantially apart from the inner surface of the reaction container, and immersing the porous tubular supportcompletely in the reaction solution so that the inside of the porous tubular supportis filled with the reaction solution; and heating the reaction solution under conditions of leaving the top and bottom ends of the porous tubular supportopen, and an apparatus using thereof and zeolite tubular separation membranes thus obtained.
