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 ... -
Ethylene Oxychlorination on CuCl2 based Catalysts: Mechanism and Kinetics
Fenes, Endre (Doctoral theses at NTNU;2021:114, Doctoral thesis, 2021)Ethylene oxychlorination is one of the major industrial sources of vinyl chloride, the monomer of poly-vinyl chloride (PVC). The oxychlorination reaction is catalysed by alumina supported, CuCl2 based catalysts which ... -
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 Study of the Oxychlorination Process
Fenes, Endre (Master thesis, 2015)The aim of this paper is to investigate the performance and stability of the non-promoted, potassium, cerium and mixed potassium/cerium promoted CuCl2/gamma-Al2O3 during oxychlorination of ethylene using mass spectroscopy ... -
Origin of potassium promotion effects on CuCl2/gamma-Al2O3 catalyzed ethylene oxychlorination
Qi, Yanying; Fenes, Endre; Ma, Hongfei; Wang, Yalan; Fuglerud, Terje; Marco, Piccinini; Chen, De (Peer reviewed; Journal article, 2020)Potassium promoters are widely used in industrial catalysts of ethylene oxychlorination to achieve optimum performance. However, the origin of the promoter effect is not fully understood. Herein, we investigated the potassium ... -
