Methanol to propylene industrialization project started
On October 18, an industrial pilot project for methanol-to-propylene (MTP) using fluidized bed technology was officially launched in Huaihe. This initiative is a joint effort between China National Chemical Engineering Group Corporation, Tsinghua University, and Anhui Huaihua Group Co., Ltd., which is part of the new-generation coal (energy) chemical industry technology innovation strategic alliance. The project aims to process 30,000 tons of methanol annually, producing approximately 10,000 tons of propylene and 800 tons of liquefied petroleum gas (LPG). With a total investment of around RMB 160 million, it is expected to be commissioned and start operations in March 2009.
Coal-to-olefins technology is a key component in the development of the modern coal chemical industry and represents a critical direction for future growth. Although methanol-to-olefins and methanol-to-propylene technologies have been researched both domestically and internationally, large-scale industrial implementation has yet to be achieved. This project aims to bridge that gap.
Based on earlier small-scale research conducted at Tsinghua University, the project has scaled up from a 1,000-ton test unit to a 10,000-ton scale. Through operational testing, process optimization, catalyst performance evaluation, and equipment reliability assessment, the project seeks to achieve advanced technical and environmental standards. These results will serve as a foundation for the future construction of a one-million-ton industrial facility.
The project is divided into three main components: basic research, industrial scaling, and field testing. Each participating organization contributes its strengths—Tsinghua University handles the small-scale testing in its reaction engineering laboratory, China National Chemical Engineering Corporation oversees the engineering design, and Anhui Huaihua Group builds the industrial test facility. This collaboration forms an integrated model of research, design, and production.
Currently, China Tianchen Chemical Engineering Co., Ltd., a subsidiary of China National Chemical Engineering Group, has completed the design of the industrial test process package. Donghua Engineering Technology Co., Ltd. is now working on the engineering design. With strong local government support, all necessary approvals and filings have been finalized, and the site is now ready for construction.
