CN102139228B - Catalyst for preparation of hydrogen through hydrolysis and production method thereof - Google Patents

Abstract

The invention provides a catalyst for the preparation of hydrogen through hydrolysis. Mixture of Co-B powder and paper pulp foam is adhered and fixed on a foamed nickel sheet, wherein the ratio of the Co-B powder to the paper pulp foam is 2:0.5-1.5 based on weight. A production method of the catalyst for the preparation of the hydrogen through hydrolysis comprises the following steps of: a, preparing CMC (carboxymethylcellulose) dilute solution; b, preparing the mixture of the Co-B powder and the paper pulp foam; c, adding the CMC dilute solution into the mixture of the Co-B powder and the paper pulp foam, wherein the ratio of the Co-B powder and the paper pulp foam to the CMC dilute solution is 1:3-5 based on the weight, and sufficiently stirring and mixing the mixture until all mixture is homogenized to form a soft daub-shaped body; d, coating the soft daub-shaped body on the foamed nickel; and e, drying the foamed nickel coated with the soft daub-shaped body for 0.6-2 hours at the temperature of 70-90 DEG C to obtain a finished product. During the preparation process, the harm is very small; the harm of alkaline stimulation can be avoided as long as operations are regular; the operation method is simple, and is easy to control; and the catalyst can be recovered for processing, and can be recycled after being used.

Description

A kind of hydrolytic hydrogen production is with catalyst and production method thereof

Technical field:

The present invention relates to water hydrogen manufacturing production technical field, more specifically to a kind of hydrolytic hydrogen production with catalyst and production method thereof.

Background technology:

At present, domestic use borane sodium (NaBH ₄) catalyst that uses of hydrolytic hydrogen production all is disposable, its weak point is: can't re-use after 1, catalyst uses up, make the hydrogen manufacturing cost high.2, harm is bigger in the preparation process, be prone to produce the harm that alkalescence stimulates, and has a strong impact on the respiratory system and the skin of human body; 3, create conditions higherly, very inconvenience operates.

Summary of the invention:

The object of the invention is exactly the deficiency to prior art; And provide a kind of hydrolytic hydrogen production with catalyst and production method thereof, in its preparation process harm very little, as long as the harm that standard operation can avoid alkalescence to stimulate; Method of operating is simple and easy to control, uses the back to reclaim processing and can use repeatedly.

Technological solution of the present invention is following:

A kind of hydrolytic hydrogen production is used catalyst, on the nickel foam sheet, is adhesively fixed with the mixture of Co-B powder and paper pulp foam, wherein, and Co-B powder by weight: paper pulp foam=2: 0.5～1.5.

A kind of hydrolytic hydrogen production is with the production method of catalyst, and a, carboxyl methyl cellulose by weight: pure water=1: 0.5～2 take by weighing CMC and pure water, pours in the container fully mixing and stirring again into, obtains the CMC dilute solution;

B, Co-B powder by weight: paper pulp foam=2: 0.5～1.5 take by weighing Co-B powder and paper pulp foam, in the paper pulp foam, pour the abundant mixing and stirring of Co-B powder into, obtain Co-B and paper pulp foam mixture;

C, Co-B and paper pulp foam mixture by weight: CMC dilute solution=1: 3～5, add the CMC dilute solution in Co-B and the paper pulp foam mixture, fully mix then up to whole mixtures and evenly become flexible glue mud shape body;

D, be coated in flexible glue mud shape body on the nickel foam;

E, under 70～90 ℃ of temperature, dry the nickel foam that coats flexible glue mud shape body and to get product in 0.6～2 hour.

Beneficial effect of the present invention is:

1, this catalyst with NaBH ₄In the hydrolytic hydrogen production process, Co-B powder difficult drop-off in 100 ℃ of high temperature vigorous reactions, the Co-B waste seldom can be disregarded in the hydrogen production process.

2, produce the cost extremely low (subtracting 65%) of equal quality Co-B.

3, harm is very little in the preparation process, if the harm that standard operation can avoid alkalescence to stimulate,

Especially respiratory system and people's skin.

4, reaction starting and temperature are all easy to control.

5, this catalyst can use in continuous 120 hours, compared with prior art, and existingization hydrogen sodium (NaBH ₄) catalyst that uses of hydrolytic hydrogen production all is disposable, can't reclaim again and continue to use, can reclaim processing after the present invention uses and use repeatedly.
