Embodiment 1

[0045] see figure 2 , the invention discloses a method for preparing a membrane separator of methanol-water hydrogen production equipment, the method comprising the following steps:

[0046] 【Step S1】If figure 1 As shown, the metal palladium membrane tube 1 and the ceramic membrane tube 2 were prepared respectively; the material of the metal palladium membrane tube was stainless steel, the material of the ceramic membrane tube was a mixture of zirconia, titania, and alumina, and zirconia, titania, and alumina The weight ratio is 2~5:3~20:5~60. For example, the weight ratio of zirconia, titanium oxide, and aluminum oxide is 2:3:5, or 4:10:59, and so on. Certainly, the material of the ceramic membrane tube may also include other materials.

[0047] [Step S2] Fill the joint part 3 of the metal palladium membrane tube 1 and the ceramic membrane tube 2 with a set filler, the filler is a mixture of a silicate polymer curing agent and a silicate crosslinking agent, silicon The w...

Embodiment 2

[0055] The difference between this embodiment and Embodiment 1 is that in this embodiment, in step S3, the filling is heated at a temperature of 50°C for 3 to 5 hours (such as 3 hours, 4 hours or 5 hours), and the filling The materials are sintered on site at the joints of metal palladium membrane tubes and ceramic membrane tubes.

Embodiment 3

[0057] The difference between this embodiment and Embodiment 1 is that in this embodiment, in step S3, the filling is heated at a temperature of 300°C for 20 to 40 minutes (such as 20 minutes, 30 minutes or 40 minutes), and the filling The materials are sintered on site at the joints of metal palladium membrane tubes and ceramic membrane tubes.

Abstract

The invention discloses a membrane separator for methyl alcohol water hydrogen production equipment and a fabrication method of the membrane separator. The method comprises the following steps that Step S1, a metal palladium membrane tube and a ceramic membrane tube are fabricated respectively; Step S2, set packing is filled in joint parts at one end of the metal palladium membrane tube and one end of the ceramic membrane tube; an expansion coefficient of the packing falls in between those of a metal palladium membrane tube material and a ceramic membrane tube material; and Step S3, the packing is sintered on site at 50-1000 DEG C, and solidified; and the joint parts of the metal palladium membrane tube and the ceramic membrane tube are sealed. With the adoption of the fabrication method of the membrane separator for the methyl alcohol water hydrogen production equipment, the membrane separator with good sealability can be fabricated, so that the preparation efficiency of hydrogen is ensured.

Description

technical field [0001] The invention belongs to the technical field of new energy, and relates to a methanol water hydrogen production equipment, in particular to a membrane separator of the methanol water hydrogen production equipment; at the same time, the invention also relates to the preparation of a membrane separator of the methanol water hydrogen production equipment method. Background technique [0002] Among the many new energy sources, hydrogen energy will become the most ideal energy source in the 21st century. This is because, in the case of burning the same weight of coal, gasoline and hydrogen, hydrogen produces the most energy, and the product of its combustion is water, without ash and waste gas, and will not pollute the environment; while the combustion of coal and oil produces These are carbon dioxide and sulfur dioxide, which produce the greenhouse effect and acid rain, respectively. The reserves of coal and oil are limited, while hydrogen is mainly stor...
