Methanol Fluid Catalytic Cracking to Propylene Through Design Review

The preliminary design of the fluidized bed methanol-to-propylene technology development 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. The project utilizes the methanol-fluidized catalytic cracking technology developed by Tsinghua University to produce propylene, with Huaihua Group having already set up a 10,000-ton methanol catalytic cracking system for industrial testing. The test facility is expected to be commissioned by the end of this year. It is reported that the methanol-fluidized catalytic pyrolysis technology for propylene, developed by Tsinghua University, has completed small-scale trials and is considered internationally advanced. The current project aims to scale up these results to a 10,000-ton level, providing a technical foundation for building a million-ton industrial facility. The project is divided into three main components: basic research, process scaling, and industrial testing. It will process 30,000 tons of methanol annually, converting it into 10,000 tons of propylene and producing 800 tons of liquefied petroleum gas. The total investment amounts to 170 million yuan. Experts note that coal-to-olefins technology is a key innovation in the new coal chemical industry and represents a major future direction for the sector. The construction of the methanol-to-propylene pilot plant will help develop proprietary technology for producing propylene from methanol. With rising global oil prices, using methanol as an alternative feedstock has become increasingly popular, and propylene is now a crucial platform chemical and raw material in the petrochemical 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, the country can only supply about 10.8 million tons, failing to meet the growing demand. The core of the fluidized bed methanol-to-propylene technology lies in converting Anhui’s abundant coal resources into methanol via coal-to-syngas processes, then producing low-carbon olefins from methanol—using less than half the amount of crude oil currently used for propylene production.
