Embodiment Construction

[0039] 1. Grind 1,000kg of high-carbon ferrochrome into fine powder of 200 mesh or more, put it into a reaction kettle, add a sufficient amount of sulfuric acid 3,000kg, heat it at 15°C-100°C and stir thoroughly, and the reaction dissolves, so that ferrochrome can completely generate ions (Cr 3+ , Fe 2+ ) solution, collect hydrogen, and make 40kg hydrogen of product new energy;

[0040] 2. Add water to the solution to make the soluble substances into ions, including Cr 3+ , Fe 2+ The precipitate in the solution is Si, and the suspended matter is C. The solution is filtered separately to obtain the filtrate and filter residue. The filter residue is washed, separated, and dried to obtain the product Si: 30kg and C: 70kg. The product Si is then produced into polysilicon and single crystal. silicon, the filtrate contains Cr 3+ , Fe 2+ solution and trace metal ions;

[0041] 3. Add oxalic acid 650Kg in the filtrate to make Fe 2+ Completely precipitated as FeC 2 o 4 , filter...

Abstract

The invention relates to a carbon ferrochrome liquid phase method for preparing a new energy battery raw material and a new energy source hydrogen process. The process is advanced, energy saving and environmentally friendly, free from fire coal and high temperature and high pressure, the new energy source, a plurality of new energy source battery materials, pigments, chemical engineering chromium salt and the like products can be produced in disposable by using ferrochrome as the raw material by using the liquid phase method, a series of new high-end industry chains are formed, the situations that the original product use is single in use and the production is pure are changed, the enterprise international competitiveness is greatly enhanced, the upgrading and optimization and development of the nation industry are promoted, and the process has important significance.

Description

technical field [0001] The invention relates to a process for manufacturing new energy battery materials and new energy hydrogen by a carbon-chromium-iron liquid-phase method, and belongs to the technical field of producing new energy battery materials and new energy using metallurgical products as raw materials. Background technique [0002] Due to the rapid development of the global economy, the demand for energy is increasing day by day. With the reduction of coal, natural gas, petroleum and other raw materials, there is an urgent need for new materials and new energy to meet the needs of economic development. New energy sources such as solar energy, hydrogen energy, and wind energy will become new developments and demands. New energy requires new battery materials, and new battery materials mainly include: silicon, carbon, metals, metal oxides, metal salts and other materials. Its production process is complex, the product is single, and the cost is high. [0003] The...
