The world's first demonstration device for 1,000 tons/year production of gasoline from carbon dioxide (CO2) hydrogenation located in Zoucheng Industrial Park, Shandong province, China has completed its trial operation and technology assessment on March 4.
The project was jointly developed by the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS) and Zhuhai Futian Energy Technology Co., Ltd.
Hydrogenation of CO2 into liquid fuels and chemicals can not only realize the resource utilization of CO2, but also facilitate the storage and transportation of renewable energy.
However, the activation and selective conversion of CO2 are challenging. A technology that can selectively produce value-added hydrocarbon fuels with high energy density will provide a new route for promoting clean and low-carbon energy revolution.
The technology of carbon dioxide hydrogenation to gasoline was proposed by SUN Jian, GE Qingjie and WEI Jian from DICP in 2017, with a paper published in Nature Communications.
The demonstration device has been completed in Zoucheng Industrial Park, in 2020. In October 2021, the device passed the continuous 72-hour on-site assessment organized by China Petroleum and Chemical Industry Federation (CPCIF). It could realize both CO2 and H2 conversion of 95%, gasoline selectivity of 85% in all carbon-based products, with reduced consumption of the raw material of CO2 and H2.
It produced clean and green gasoline product with octane number more than 90 conforming to the Chinese national VI standard, accompanied by low energy consumption of the whole process.
"This technology marks a new stage of CO2 resource utilization technology in the world, and provides a new strategy for realizing the goal of carbon neutral," said Prof. SUN.
This work was supported by the Strategic Priority Research Program of "Key Technologies and Demonstration of Transformative Clean Energy" of CAS, the National Natural Science Foundation of China, and the Liaoning Talents Program.
