Cluster-size-dependent interaction between ethylene and CuCl2 clusters supported via γ-alumina
Qi, Yanying; Fenes, Endre; Ma, Hongfei; Wang, Yalan; Rout, Kumar Ranjan; Fuglerud, Terje; Marco, Piccinini; Chen, De (Peer reviewed; Journal article, 2020)Alumina-supported copper chloride serves as an industrial catalyst for ethylene oxychlorination, resulting from its high activity and selectivity. A better understanding of the detailed active site structure and reaction ... -
Kinetic modeling of dynamic changing active sites in a Mars-van Krevelen type reaction: Ethylene oxychlorination on K-doped CuCl2/Al2O3
Ma, Hongfei; Sollund, Erling S.; Zhang, Wei; Fenes, Endre; Qi, Yanying; Wang, Yalan; Rout, Kumar Ranjan; Fuglerud, Terje; Piccinini, Marco; Chen, De (Peer reviewed; Journal article, 2020)A kinetic model was developed by taking into account the dynamic nature of the active sites in Mars–van Krevelen type catalytic reactions to predict the evolution of the reactant and product composition in the gas phase ... -
Kinetic Modeling of Oxychlorination Reaction
Wiker, Ellinor Sofie Smith (Master thesis, 2016)Polyvinyl chloride is a widely produced plastic polymer due to its various applications and relatively low cost. Oxychlorination of ethylene to 1,2-dichloroethane is an important step in the production of vinyl chloride ... -
Kinetic Studies of Ethylene Oxychlorination to Ethylene Dichloride and Vinyl Chloride
Ma, Hongfei (Doctoral theses at NTNU;2021:85, Doctoral thesis, 2021)Polyvinyl chloride (PVC) is the most versatile of all thermoplastics that can be used in a wide range of applications. It is the third-highest volume polymer, slightly behind polyethylene and polypropylene. Vinyl chloride, ... -
Kinetic study and reactor modeling of ethylene oxychlorination
Sollund, Erling Olav (Master thesis, 2018)Oxychlorination of ethylene to 1,2-dichloroethane is a vital step in the production of polyvinyl chloride. Polyvinyl chloride is a plastic polymer that is widely used, especially in construction. The reaction is usually ... -
