Problems solved by technology
[0003] At present, several main ways to prepare hydrogen include by-product hydrogen in chlor-alkali industry, hydrogen production by electrolysis of water, hydrogen production from chemical raw materials (methanol cracking, ethanol cracking, liquid ammonia cracking, etc.), hydrogen production from petrochemical resources (petroleum cracking, water gas method, etc.) And new hydrogen production methods (biomass, photochemical, etc.), but for the by-product hydrogen of the chlor-alkali industry, it is necessary to consider the cost pressure that the long-distance transportation of hydrogen may increase, while the hydrogen production by electrolysis of water has high manufacturing costs, high liquefaction costs, and difficult Storage and other issues

Embodiment 1
[0017] Embodiment 1: A kind of method that utilizes active metal to prepare hydrogen, utilizes sodium and water to react under kerosene medium to prepare hydrogen, described sodium is wrapped with aluminum to make aluminum rod, and described aluminum rod is provided with small hole; The proportion of water volume is 6%-12%.
[0018] For specific implementation, refer to the attached figure 1 As shown, the aluminum rod 2 wrapped with sodium is placed longitudinally in the reaction vessel 1. The aluminum rod is made of 120g aluminum wrapped with 2-6g sodium, and its surface is evenly opened with holes, and then 50ml As for the kerosene in the reaction vessel, immerse the aluminum rod in the kerosene layer 4, then slowly inject 3ml of water into the kerosene, the water and the kerosene are separated, and the water is located below the kerosene to form a water layer 3, and the kerosene is located above the water. When the sodium inside the rod package comes into contact with a tr...

The invention discloses a method for preparing hydrogen by using active metal. Sodium and water react under a kerosene medium to prepare hydrogen, the sodium is wrapped by aluminum to prepare an aluminum bar, and the aluminum bar is provided with small holes. According to the method, the sodium wrapping aluminum reacts with the water under the kerosene medium, the contact between the sodium and the trace water is controlled through the small holes in the wrapping aluminum, the reaction rate of the sodium and the water is further controlled, so that the hydrogen is continuously and safely prepared for a long time, the aluminum-containing alkaline liquid obtained after hydrogen preparation can be recycled through different means, and the method is suitable for industrial production, can avoid environmental pollution, and has environmental protection significance.
Description
technical field [0001] The invention relates to the technical field of energy processing, in particular to a method for preparing hydrogen by using active metals. Background technique [0002] The traditional petrochemical energy is a non-renewable energy. With continuous exploitation, its storage capacity is also declining. Over time, countries all over the world are facing an energy crisis. In order to cope with the energy crisis, all countries are looking for alternative new energy sources, such as wind power, photovoltaics, etc., and when hydrogen is burned, only water is produced, and the combustion calorific value is high, the combustibility is good, non-toxic and pollution-free, transportation There are many advantages such as less loss and preservation in various forms. Replacing fossil fuels can minimize the greenhouse effect. For the development of hydrogen energy, the three important links in the industrial chain are hydrogen production, hydrogen storage and fuel ...
