By the end of this year, a 10,000-ton industrial testing facility for methanol-to-propylene technology is expected to be completed. The preliminary design of the fluidized bed methanol-to-propylene project has recently received approval from the Anhui Provincial Development and Reform Commission. This initiative is a joint effort between China National Chemical Engineering Corporation and Huaihua Group. It utilizes the methanol-fluidized catalytic cracking technology developed by Tsinghua University, and Huaihua Group has already established a 10,000-ton methanol catalytic cracking system for propylene production. The facility is set to begin operations by the end of the year.
The technology, developed by Tsinghua University, has already passed small-scale testing and is recognized as internationally advanced. The current project aims to scale up these results to a 10,000-ton level, laying the technical foundation for the construction of a million-ton industrial plant. The project consists of three key components: basic research, process scaling, and industrial testing. It is designed to process 30,000 tons of methanol annually, producing 10,000 tons of propylene and 800 tons of liquefied petroleum gas. A total investment of 170 million yuan has been allocated, with completion planned for the end of 2024.
Experts highlight that coal-to-olefin technology represents a crucial innovation in the new coal chemical industry, and it is seen as a key direction for future development. The construction of this methanol-to-propylene pilot plant will help establish a proprietary technology for producing propylene from methanol. With rising global oil prices, methanol is increasingly being used as an alternative feedstock in petrochemicals, and propylene is becoming a vital platform chemical in the industry.
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 lies in converting Anhui’s abundant coal resources into methanol through coal-to-syngas processes, then producing low-carbon olefins. This method offers a more efficient and sustainable way to produce propylene, using less than half the amount of crude oil currently required.
