【Ten Years of Great Progress in Chemical Technology】175-2023: The World’s First 10,000-ton-per-year Project for Producing Maleic Anhydride via Hydrogenation of Petroleum-Based Succinic Anhydride
Thread Content
Ten years of rapid development in chemical technology – praise for China’s prosperity and strength. This is just a starting point; more participation from everyone will make things even more lively. HaiChuan becomes even better with you here; we welcome everyone to join in the forum discussions. It’s hot in July, so be careful to prevent fires. --------------------------------------------Recently, Xuke New Materials (Shandong) Co., Ltd. (referred to as “Xuke New Materials”) has successfully produced high-quality maleic anhydride with a purity of over 99.5%, making it the world’s first project to produce maleic anhydride on a scale of 10,000 tons per year through the hydrogenation of petroleum-based succinic anhydride. XuKe New Materials is a newly established enterprise in Ju County that produces raw materials for biodegradable plastics. On May 31 of this year, the first phase of Xukē New Materials (Shandong) Co., Ltd.’s project, with an annual production capacity of 10,000 tons of succinic anhydride and succinic acid, began operations. On June 6, high-quality maleic anhydride with a purity of over 99.5% was produced stably. The product exhibited excellent quality, high purity, and a low color intensity, reaching international advanced standards. This marks the successful commissioning of the world’s first oil-based production facility capable of manufacturing ten-thousand-ton quantities of maleic anhydride through the hydrogenation of succinic anhydride; it is also the largest production plant of this type in the world to date. The successful commissioning of a enterprise in just one attempt is made possible by the strong drive of technological innovation.
The large-scale production of succinic anhydride is constrained by factors such as stringent reaction conditions and high production costs, making the development of production technologies challenging. At present, most domestic enterprises use pilot plants with a capacity of a few thousand tons; strict control is exercised over process parameters during product production, which imposes very high requirements on the safety of such facilities.
Building on the successful completion of the first phase of its project, Xukē New Materials will accelerate the expansion of its production capacity. In the second phase, it will construct one facility for producing 200,000 tons of maleic anhydride, one facility for producing 100,000 tons of PBAT, one facility for producing 100,000 tons of PBS, one facility for producing 100,000 tons of BDO, and one facility for producing 100,000 tons of succinic anhydride. By leveraging advanced technologies, Xukē New Materials aims to become a leader in the light hydrocarbon industry chain and contribute to the development of new chemical materials. ”When talking about the future development of the company, Wang Xin, deputy general manager of Xukewang New Materials (Shandong) Co., Ltd., is full of confidence. XuKe New Materials (Shandong) Co., Ltd. is a Sino-foreign joint venture registered in Juxian County, Rizhao, Shandong, specializing in biodegradable polyesters and related fine chemical products. The company utilizes advanced manufacturing technologies to focus on the research, development, production, sales, and service of high-performance new materials. Adhering to the concept of a circular economy, aiming for technological leadership, and pursuing scale integration, the company is committed to addressing the increasingly severe environmental problems facing humanity, actively coping with the challenges posed by changes in the global living environment, and achieving sustainable development.
