Although the domestic hydrogen peroxide industry has developed rapidly in recent years and the production technology level has also improved, it is optimized and improved on the basis of the fixed bed hydrogenation process. Compared to the domestic production of hydrogen peroxide, the Fluidized Bed Hydrogen Peroxide Processes technology has obvious features and advantages:
1. The scale of production is greater. Several companies with the largest production of hydrogen peroxide in foreign countries have formed their own unique production technology and supporting production equipment, basically adopting fluidized bed hydrogenation process, and the scale of single set of equipment is large, and the production scale of hydrogen peroxide can reach 330,000 tons. 100% concentration meter, hydrogenation efficiency 18g / L).
2. More efficient production. For example, Hubei Sanli Fengxiang Technology Co., Ltd. uses high-capacity working fluid, fluidized bed hydrogenation and other advanced processes, and the hydrogenation efficiency is above 12.5g/l-15g/L, which is higher than the hydrogenation efficiency of domestic hydrogen peroxide technology. 7.5-8.5g/L) is 50% higher, that is, the production capacity per unit volume of working fluid increases by 50% in each cycle. It greatly improves the production efficiency of the device and reduces the amount of circulating working fluid; it can directly produce hydrogen peroxide at a concentration of 35-43%; the total yield of the process is high.

3. The process is simpler, the production is safer, and the product is better. There is no K2CO3 drying tower and related control problems in the production process, so the process is greatly simplified; essentially eliminating the safety hazard of hydrogen peroxide decomposition in the production system due to alkaline problems, the product quality is higher. The product does not contain acid-base neutralized inorganic salts and other impurities brought by potassium carbonate. It is more versatile and is advantageous for further production of high-purity hydrogen peroxide, such as food grade and electricity grade hydrogen peroxide.
4. Hydrogen Peroxide Technology has obvious energy saving and effective reduction of production cost.
5. Less investment. Both the Hydrogen Peroxide Plant investment and the working fluid and palladium catalyst required for the first production have been reduced.
