New direction for clean energy China's "syngas to high-carbon alcohol" made key progress
Syngas is a raw material gas used for chemical synthesis with hydrogen and carbon monoxide as the main components. It is derived from the conversion of coal, petroleum, natural gas and coke oven gas, sludge and biomass. Under the action of catalysts, syngas can produce a series of chemicals, but usually requires "multiple steps", and the cost increases accordingly.
The above-mentioned technology innovatively uses a new cobalt-cobalt carbide-based catalyst supported on a carbon material developed by the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences to complete the world's first synthesis gas high-alcohol co-production liquid in a large-scale slurry bed reactor. 10,000-ton industrial test of fuel. Experts of the appraisal committee agree that the catalyst has been granted 11 invention patents, which belongs to original technology, advanced indicators, strong applicability, and ranks at the international advanced level.
High-carbon alcohol is an important fine chemical raw material. It is used to synthesize plasticizers, detergents, surfactants, and a variety of fine chemicals. Subsequent processed products are widely used in textile, papermaking, and pharmaceutical fields. The promotion and implementation of this project is expected to provide a cheap and sufficient source of high-carbon alcohol raw materials for the fine chemical industry.
In addition, by adjusting the catalyst, the project can change the ratio of high-carbon alcohol to liquid fuel in the product, and improve the economic benefits of coal-to-fuel enterprises.
The project was jointly carried out by the Dalian Institute of Chemical Technology of the Chinese Academy of Sciences and Shaanxi Yanchang Petroleum Yulin Coal Chemical Co., Ltd., which was officially launched in 2018. From October 31st to November 3rd this year, the industrial test passed the continuous 72-hour catalyst performance assessment organized by the China Petroleum and Chemical Industry Federation. At a device load of 30%, the total conversion of syngas is greater than 84%, the selectivity of methane is lower than 6%, and the total selectivity of alcohol / aldehyde is higher than 42%.
