Hydrogen peroxide method propylene oxide technology is internationally advanced

Recently, the hydrogen peroxide method propylene oxide technology independently developed by China Tianchen Engineering Co.
, Ltd.
, a subsidiary of China Chemical, passed the scientific and technological achievement appraisal organized by the Tianjin Science and Technology Achievement Evaluation Center
.
The appraisal expert group headed by Academician of the Chinese Academy of Engineering and Professor Jian Xigao of Dalian University of Technology believes that the technical achievement has generally reached the international advanced level
.

The hydrogen peroxide method propylene oxide technology uses propylene and hydrogen peroxide as raw materials, adopts a catalyst system independently developed, and has strong technological innovation, and has obtained 23 Chinese patents
.
Compared with the traditional chlorohydrin method, the hydrogen peroxide method propylene oxide technology reduces the consumption of propylene, the amount of waste water and the discharge of waste residue
.
The technology is also in line with the "Industrial Structure Adjustment Guidance Catalogue (2019 Edition)" issued by the National Development and Reform Commission, which is conducive to promoting the industrial upgrading of the propylene oxide industry
.

The first industrial demonstration plant built on this technology has been successfully put into production in May 2021, and the products have reached the national standard premium level
.
In January 2022, Tianchen Company, strategic investors, employees and investment platforms jointly established a project company, and invested in the construction of the first phase of the 600,000-ton/year propylene oxide project in Quangang, Fujian
.
In addition, multiple units with a single capacity of 150,000 to 300,000 tons per year are also under construction
