Oil production from the 10,000-ton per year coal-to-methanol gasoline production pilot project in Shanxi

According to the China Chemical Industry News, on January 13, 2009, the National Coal Chemical Engineering Technology Center reported that China’s first 10,000-ton-scale industrial test plant using methanol-to-gasoline technology based on domestic intellectual property rights completed industrial tests for converting methanol into gasoline in Jincheng, Shanxi, producing qualified gasoline products. This marked a new approach for the conversion of coke oven gas and the further processing of methanol. Among the coal chemical technology routes, methanol synthesis is one of the most mature technologies, which has led to the implementation of numerous methanol projects. Statistical data show that by 2010, China’s methanol production capacity would reach 15 million tons per year, with the capacity of methanol plants that have been approved or registered amounting to 34 million tons. The capacity of methanol production facilities in our country will **exceed market demand, making it urgent to develop downstream application technologies that can convert methanol on a large scale. Li Dashang, a master of engineering design in China and director of the National Coal Chemical Engineering Design Technology Center, told reporters that the technology for converting methanol into gasoline was first developed by Mobil in the 1970s. An industrial facility capable of producing 12,500 barrels of gasoline per day was built in New Zealand in the 1980s, but it was shut down for various reasons. Compared with other downstream methanol technologies, this 10,000-ton industrial test facility features a relatively simple process for converting methanol into gasoline, and it holds certain advantages in terms of reactor technology, oil product post-treatment technology, and oil product quality. In particular, the gasoline produced by methanol conversion can be used directly after simple processing. The methanol-to-gasoline (MTG) pilot project laid the foundation for scaling up industrial-scale production facilities from those with a processing capacity of tens of thousands of tons. It will create a broad market for the advanced processing of methanol in China, offering strong market competitiveness ; At the same time, it finds practical and high-value pathways for making use of the abundant high-sulfur anthracite in Shanxi Province, providing technical support for the large-scale industrialization of China’s coal-to-oil industry in the future. It is reported that this device has already been granted a utility model patent for the \"methanol-to-gasoline reactor,\" with an invention patent application currently in progress. This testing apparatus consumes 2.58 tons of methanol, 343 tons of circulating water, and 410 kWh of electrical power per ton of gasoline. The light gasoline produced has low levels of olefins and no benzene content, as well as no sulfur. It meets the standards for **93-grade automotive gasoline, as verified by the **Fuel Oil Quality Supervision and Inspection Center. It is understood that experts from national coal chemical engineering companies and the coal chemical industry in Shanxi, based on years of research, development, testing, and screening of catalysts for converting methanol into gasoline, completed the process software package at a scale of 10,000 tons, as well as the basic and detailed engineering designs in 2005. In 2006, they finished the installation of an industrial-scale testing facility capable of handling 10,000 tons per year, and in 2007 they developed a viable operational plan.
