Membrane tube and reactor having a membrane tube

摘要

The invention relates to a diaphragm pipe for permeative separation of hydrogen from gas mixtures containing hydrogen, a method for the production thereof as well as a reactor comprising a diaphragm pipe, wherein the diaphragm pipe comprises a porous pipe (S) made of a sintered metal and a diaphragm (M) containing palladium or made of palladium enclosing the outer surface of the sintered metal pipe (S). The sintered metal pipe (S) has at least on one end a fitting (F) made of gasproof material, which is firmly connected with the sintered metal pipe (S).

主权项

1. A membrane tube for the permeative separation of hydrogen from hydrogen-containing gas mixtures, said membrane tube comprising:
a porous tube made of a sintered metal and a membrane which contains palladium and encloses the outside of the sintered metal tube, wherein said sintered metal tube has, at at least one end, a fitting which consists of a gastight material, said membrane projects beyond said sintered metal tube at said at least one end and said membrane is joined in a gastight manner to said fitting, and said fitting is in the shape of a first hollow cylinder and a second hollow cylinder, with the external diameter of said first hollow cylinder being identical to the external diameter of said sintered metal tube, and the external diameter of said second hollow cylinder being essentially identical to the internal diameter of said sintered metal tube such that said second hollow cylinder is positioned within said sintered metal tube.
