Development of Polyethylenimine (PEI)-impregnated mesoporous carbon spheres for low-concentration CO2 capture

Chen, Qingjun; Wang, Siyu; Rout, Kumar Ranjan; Chen, De (Journal article; Peer reviewed, 2020)

A novel low-concentration CO2 capture material (PEI/MCS) was developed by loading polyethylenimine (PEI) over mesoporous carbon spheres (MCS) with high porosity. The effects of pore structure, PEI loading, capture temperature, ...
Effect of trace potassium on hydrogen adsorption and dissociation on hcp cobalt: A density functional theory study

Chen, Qingjun; Svenum, Ingeborg-Helene; Gavrilovic, Ljubisa; Chen, De; Blekkan, Edd Anders (Journal article; Peer reviewed, 2018)

Trace amounts of potassium (K) have a significant influence on the activity and selectivity of cobalt-based catalysts in Fischer–Tropsch synthesis (FTS), in which hydrogen adsorption and dissociation is one of the initial ...
Nitrogen‐Doped Carbon-Assisted One‐pot Tandem Reaction for Vinyl Chloride Production via Ethylene Oxychlorination

Ma, Hongfei; Ma, Guoyan; Qi, Yanying; Wang, Yalan; Chen, Qingjun; Rout, Kumar Ranjan; Fuglerud, Terje; Chen, De (Peer reviewed; Journal article, 2020)

A bifunctional catalyst comprising CuCl2/Al2O3 and nitrogen‐doped carbon was developed for an efficient one‐pot ethylene oxychlorination process to produce vinyl chloride monomer (VCM) up to 76 % yield at 250 °C and under ...
Potassium adsorption behavior on hcp cobalt as model systems for the Fischer–Tropsch synthesis: a density functional theory study

Chen, Qingjun; Svenum, Ingeborg-Helene; Qi, Yanying; Gavrilovic, Ljubisa; Chen, De; Holmen, Anders; Blekkan, Edd Anders (Journal article; Peer reviewed, 2017)

Potassium (K), an important impurity in syngas from biomass, can have a large influence on the activity and selectivity of cobalt-based Fischer–Tropsch synthesis (FTS) catalysts in Biomass to Liquids (BTL) processes. In ...
