A pilot Fischer–Tropsch technology for producing chemicals rich in long-chain olefins has passed a 72-hour assessment. It was jointly developed by the Shanghai Advanced Research Institute of the Chinese Academy of Sciences and Chongqing Lanze Energy Technology. The assessment took place from May 25 to 28 and was organized by the China Petroleum and Chemical Industry Federation.

Experts inspected the pilot plant, reviewed the operating conditions of key systems and examined original data records. They checked the stability and consistency of the plant’s operation.

During the continuous assessment, process parameters remained steady and key equipment operated safely and reliably. The plant maintained stable operation under high load.

The report says synthesis gas derived from coal, natural gas, biomass, CO2 and solid waste can be converted through the Fischer–Tropsch route into long-chain olefins and other high-value chemicals. Challenges in the field include a high share of C1 by-products and low selectivity and yields for target chemicals.

The core catalyst for the pilot technology was developed by the Shanghai institute’s Green Carbon Science team. It is characterized by low carbon emissions and a high olefin yield.
