Critical review of catalysis for ethylene oxychlorination
Ma, Hongfei; Wang, Yalan; Qi, Yanying; Rout, Kumar Ranjan; Chen, De (Peer reviewed; Journal article, 2020)Ethylene oxychlorination is the key technology in vinyl chloride (VCM, the monomer of PVC, polyvinyl chloride) production to close the chlorine loop by consuming the HCl released from the former cracking step. Due to the ... -
Effect of oxide additives on the hydrotalcite derived Ni catalysts for CO2 reforming of methane
Niu, Juntian; Liland, Shirley Elisabeth; Yang, Jia; Rout, Kumar Ranjan; Ran, Jingyu; Chen, De (Peer reviewed; Journal article, 2018)Here we provide new mechanistic and kinetic insights into the functions of oxides on Ni catalysts in methane dry reforming combining kinetic studies with density functional theory (DFT) calculations. Hydrotalcite derived ... -
Fischer-Tropsch synthesis over an alumina-supported cobalt catalyst in a fixed bed reactor – Effect of process parameters
Gavrilovic, Ljubisa; Jørgensen, Erik Andreas; Pandey, Umesh; Putta, Koteswara Rao; Rout, Kumar Ranjan; Rytter, Erling; Hillestad, Magne; Blekkan, Edd Anders (Peer reviewed; Journal article, 2020)Fischer-Tropsch synthesis has been investigated over a commercial type cobalt-based catalyst (20 %Co/0.5 %Re/γ-Al2O3) by varying the H2/CO ratio (2.55–1.12), CO conversion (15–75 %), reaction temperature (210 °C, 230 °C), ... -
