By the end of this year, a 10,000-ton methanol-to-propylene pilot plant will be completed. Recently, the preliminary design of the fluidized bed methanol to propylene technology development project was approved by the Anhui Provincial Development and Reform Commission. This initiative is a joint effort between China National Chemical Engineering Corporation and Huaihua Group. The technology used in the project is based on the methanol-fluidized catalytic cracking process developed by Tsinghua University. Huaihua Group has already set up a 10,000-ton methanol catalytic cracking system for industrial testing, with the device expected to be operational by the end of the year. The methanol-fluidized catalytic pyrolysis technology for propylene, developed by Tsinghua University, has already passed small-scale testing and is considered internationally advanced. The current project aims to scale up this successful lab result to a 10,000-ton industrial level, laying the technical foundation for future large-scale production—potentially reaching one million tons annually. The project consists of three main components: basic research, process optimization, and industrial testing. It will process 30,000 tons of methanol per year, producing 10,000 tons of propylene and 800 tons of liquefied petroleum gas. A total investment of 170 million yuan is planned, with completion expected by year-end. Experts note that coal-to-olefin technology is central to the evolution of the modern coal chemical industry and represents a key direction for its future growth. This pilot plant will help develop an independent, proprietary technology for producing propylene from methanol. With rising global oil prices, using methanol as an alternative feedstock is becoming increasingly common. Propylene, in particular, is emerging as a crucial platform chemical in petrochemicals. According to forecasts, domestic propylene demand in China is expected to reach 19.05 million tons by 2010. However, due to limited petroleum resources, only about 10.8 million tons can be supplied, leaving a significant gap. The core of the fluidized bed methanol-to-propylene technology is to leverage advanced gasification techniques to convert Anhui’s abundant coal reserves into methanol via coal-to-syngas processes, then produce low-carbon olefins like propylene. This method offers a more efficient and sustainable alternative, producing less than half the amount of propylene currently derived from petroleum.
