300,000 tons of methyl methacrylate Phase I project started in Pu

On July 1, the groundbreaking ceremony for the first phase of the 300,000-ton methyl methacrylate (hereinafter referred to as MMA) project of Henan Zhongke Puyuan New Materials Co., Ltd. was held in Puyang Economic and Technological Development Zone. The first set of new ionic liquid-catalyzed ethylene production of MMA technology was put into use. Municipal Party Secretary Yang Qingjiu attended the event and announced the start of construction.

Zhang Tao, Vice President and Academician of the Chinese Academy of Sciences, Zhang Suojiang, Director of the Institute of Process Engineering of the Chinese Academy of Sciences, President and Academician of Henan University, Duan Xiangwei, Deputy General Manager of China National Machinery Engineering Corporation, Liang Tieshan, Chairman and Deputy Secretary of the Party Committee of Henan Energy and Chemical Group, Henan Song Kexing, Executive President of the Provincial Academy of Sciences, Shao Jingliang, Director of the Standing Committee of the Municipal People’s Congress, Xu Huiqian, Chairman of the CPPCC, Hui Kang, Member of the Standing Committee of the Municipal Party Committee and Secretary General, and Shi Yuezhi, Secretary of the Party Committee and Chairman of Zhongyuan Dahua, attended the event. Deputy Mayor Chen Xiaohua presided over the ceremony.

Yang Qingjiu said that Henan Zhongke Puyuan New Materials Co., Ltd. is jointly invested by Henan Zhongyuan Dahua Group Co., Ltd., Puyang City Financial Holdings Co., Ltd., and Puyang Economic and Technological Development Zone Urban Construction Investment Co., Ltd. and was established in March 2022. The company’s 300,000-ton new ionic liquid catalyzed ethylene-based MMA project has started construction, and has implemented the province’s overall deployment of “two guarantees” and “ten strategies”, creating a highland for scientific and technological innovation, and greatly improving Puyang’s innovation resource gathering ability and innovation. The ability to transform results is of great significance.

Introduction to new MMA technology

According to reports, the project adopts the new ionic liquid-catalyzed ethylene-based MMA technology provided by the Chinese Academy of Sciences. Using ethylene, carbon monoxide, hydrogen and methanol as raw materials, it undergoes hydroformylation reaction, aldol condensation reaction, aldehyde oxidation reaction, and esterification reaction. And the refining process produces MMA and by-product propionaldehyde. The industrialized device was jointly developed and completed by the Institute of Processes of the Chinese Academy of Sciences, Henan Energy Group Research Institute, and Zhongyuan Dahua Company after ten years of hard work. In March 2019, it passed the scientific and technological appraisal organized by the Petrochemical Federation. This technology belongs to the first domestic process, breaking the foreign technology monopoly, with completely independent intellectual property rights, obvious economic advantages, clean process, green environmental protection, reaching the international leading level.

MMA market has a bright future

MMA is a high-tech product. The downstream products are mainly PMMA, surface coatings, and PVC modifiers. They can be used to manufacture plexiglass (PMMA), coatings, lubricant additives, etc. The manufactured plexiglass (PMMA) is Liquid crystal display light guide plates, LED lamps and high-end fields such as automotive lenses and exterior decoration have been widely used; in addition, MMA is also an indispensable unit for the production of aerospace glass, optical fibers, high-performance optical lenses, electronic information devices and other major national strategic materials. body.

Zhang Tao said that the implementation of several innovative technologies of the Chinese Academy of Sciences in Puyang fully reflects the favorable business environment and diversification of Puyang City, and the personalized policy of benefiting enterprises, as well as Henan Neng Hua Group’s demand for technological innovation. It is hoped that more of our technical teams and projects can settle in Puyang, speed up the transformation of scientific and technological achievements into real productivity, and jointly build a “dual-carbon” comprehensive demonstration base to help Puyang comprehensively transform into high-quality development.

Before the commencement ceremony, the participants also went to the coal chemical plant area of ​​Zhongyuan Dahua Company to visit the pilot plant of straw sugar to ethylene glycol, the pilot plant of synthesis gas ethylene to MMA, and the key technology plant of methanol conversion to methyl nitrite.
