Abstract

The invention discloses an aluminium / water reaction controllable-hydrogen catalyst. The aluminium / water reaction controllable-hydrogen catalyst comprises the following materials in percent by weight: (a) 75%-85% of metal aluminium powder; (b) 5%-12% of mixture of bismuth chloride, sodium chloride and potassium chloride; (c) 5%-15% of mixture of metal calcium powder and metal zinc powder. A preparation method of the catalyst comprises the steps of: (1) fully stirring according to the proportion with 90% of aluminium powder and 10% of bismuth chloride, sodium chloride and potassium chloride, and mixing into an Al-BiCl3 base material; (2) fully stirring according to the proportion with 90% of Al-BiCl3 base material and 10% of metal calcium powder and metal zinc powder, and mixing into an Al-BiCl3 main material; (3) putting the Al-BiCl3 main material into a ball mill to carry out ball-milling for more than 5 hours so as to prepare a high-activity Al-BiCl3 composite material; (4) mixing and stirring the high-activity Al-BiCl3 composite material and polyacrylamide aqueous solution, preparing into blocks and then drying.

Description

technical field [0001] The invention relates to a hydrogen catalyst with controllable aluminum / water reaction, in particular to the ratio of raw materials of each formulation of the hydrogen catalyst with controllable aluminum / water reaction. Background technique [0002] Aluminum is the most abundant metal element in the earth's crust, with a wide range of sources, low price and low density. The chemical phenomenon of hydrogen production by aluminum / water reaction inspires human beings to develop the aluminum / water reverse hydrogen production technology, which provides a method for the wide application of green energy—hydrogen energy. It is likely to be an effective solution for human beings to solve the problems of energy shortage and environmental pollution. one of the paths. In my country, relevant academic institutions and experts have also published a lot on the mechanism research and application of aluminum / water reaction hydrogen production technology.

Problems solved by technology

[0010] The application research of aluminum / water reaction hydrogen production technology is mostly focused on the research and development of fuel cell applications and has achieved preliminary commercial application on mobile power supplies. The technology application area is very narrow, which is not conducive to the development of aluminum / water reaction. Extensive promotion and popularization of hydrogen production technology

As for the commercial application of the aluminum / water reaction hydrogen production system, the key lies in the design of an instant and efficient hydrogen production device. Although there have been some related designs and inventions at home and abroad, these published designs and inventions exist in the system. Complex and huge, there are technical defects that need to be overcome, such as uncontinuous reaction, inconvenient cleaning, high energy consumption, high temperature resistance, etc., and the practicability is not high, so they are not meaningful for promotion. It is a technology that limits the application and development of aluminum / water reaction hydrogen production technology the problem
