1. Research and development of ethylene glycol technology for syngas


Shanghai Wuzheng Engineering Technology Co., Ltd. owns the national invention patent for syngas to ethylene glycol (patent name: a process for producing ethylene glycol in parallel to produce dimethyl carbonate, patent number: 200810043079.0), which is the first coal in China. One of the companies that research and engineer ethylene glycol technology.

In 2009, Shandong Hualu Hengsheng's “50,000 tons/year synthetic tail gas ethylene glycol energy saving project” was provided by Shanghai Wuzheng Engineering Technology Co., Ltd. (according to the announcement in June 2011, Hualu Hengsheng The ethylene glycol project utilizes the technology of Shanghai Wuzheng Engineering Technology Co., Ltd., and after the preparation and 50,000 tons/year, the project will be extended to 300,000 tons/year. Due to various factors, the project will be put into trial production in 2012.


2. On July 2, 2012, Hualu Hengsheng announced that the ethylene glycol project was successfully put into operation and produced qualified ethylene glycol products. Since then, the technology of syngas produced by Shanghai Wuzheng Engineering Technology Co., Ltd. has been verified by large industry.


3. So far, Shanghai Wuzheng Engineering Technology Co., Ltd. has prepared more than 20 feasibility studies on coal-based ethylene glycol from Shandong, Heilongjiang, Inner Mongolia, Shanxi, Ningxia, Shaanxi, Guizhou and other enterprises. Signed a technology transfer contract with several companies.


4. Shanghai Wuzheng Engineering Technology Co., Ltd. has made great progress on this basis. At present, it has completed the finalization of the second generation industrial catalyst of ethylene glycol project and has invested in large industrial production. The third generation of catalysts has also been successfully developed. Due to its higher liquid hourly space velocity and higher yield, the company is developing a large-scale reactor that will match it, which will further reduce the investment of the plant and enhance the competitiveness of the company.


Shanghai Wuzheng Engineering Technology Co., Ltd. is making progress and is making new contributions to the development of China's syngas ethylene glycol technology and industry.
