More than 20 years of hard work came to an end.

On the eighth day of the New Year in 2020, a sudden outbreak of the epidemic hit the plant, and in order to ensure the smooth operation of the plant, a team of researchers from the Dalian Institute of Chemical Physics, Chinese Academy of Sciences (hereinafter referred to as "Dalian Institute of Chemical Physics"), Ding Yunjie, packed their bags and rushed from Dalian to Fuxin, Liaoning Province, where they lived in the plant for four months after quarantine.

At that time, the team's research and development project "Industrialization Technology of Multiphase Hydroformylation of Ethylene and its Hydrogenation to Propanol" was about to be put into operation, and the catalyst stability, product selectivity, production quality ...... Yan Li, as the team leader, had many details to control rigorously.

In August 2020, the plant was commissioned and has been running smoothly since then.

On May 14 this year, the technology passed the identification of scientific and technological achievements organized by China Petroleum and Chemical Industry Federation. The appraisal committee unanimously agreed that the invented ethylene hydroformylation metal Rh single-atom multiphase catalyst is the first technology and the overall technology has reached the international leading level, and unanimously agreed to pass the appraisal.
