Hydrogen peroxide technology

1. Introduction

Hydrogen peroxide, also known as hydrogen peroxide, is a strong oxidant and often present as a colorless and transparent aqueous solution. Hydrogen peroxide is widely used in medical disinfectants, industrial oxidants, and bleaches etc.

At present, hydrogen peroxide is mainly produced by the method of hydrazine, which is one of the most mature production methods in the industry.

During the production process, 2-alkyl hydrazine was first mixed with organic solvent to prepare a hydrazine solution (working fluid), then under certain conditions of temperature, pressure and catalyst, the hydrazine in the working fluid are hydrogenated with hydrogen to form hydroquinone mixture(hydrogenated solution).

The hydrogenated solution is then oxidized with air (or oxygen) to form a hydrogen peroxide and hydrazine mixture solution (oxidizing solution), and then the oxidizing solution is separated by extraction, and the extracted working fluid is recycled after being processed, and the flow is as follows.

To produce hydrogen peroxide, the key techniques of hydrazine process are the optimization of catalysts, working fluids and helium hydrogenation processes.

Whitefan Chemical's has a pivot patent of working fluid formulation in this technology to produce hydrogen peroxide. With the hydrogenation efficiency of 12.5-15g/L, this technology can produce hydrogen peroxide products with various concentrations. And, the total yield of hydrogen peroxide can reach 97%, and the single-line production capacity can reach 200,000 tons / year (based on 100% concentration). The schematic diagram of Whitefan Chemical’s hydrogen peroxide process is as follows:
