Dr Long Ji is an Associate Professor in College of Engineering, Huazhong Agricultural University. He was awarded a PhD degree in mineral processing engineering from China University of Mining & Technology (Beijing) in June 2018 and a second PhD degree in environmental sciences from Macquarie University (Australia) in Sep 2019. From Sep 2014 to Jun 2018, he studied with Dr Hai Yu as a joint PhD student in CSIRO Energy in Newcastle, Australia. He has been working on CO2 mineralisation and amine-based CO2 capture since 2014. He developed an “Integrated absorption-mineralisation” for low-energy CO2 capture and sequestration. Currently, he is working on CO2 mineralisation by biomass ash, nano particle promoted CO2 desorption in amine-based CO2 capture, and promoted hydrophilia of organic membrane by nano particles.
