Contactless temperature measurements under static and dynamic reaction conditions in a single-pass fixed bed reactor for CO2 methanation 10.1016/j.jcou.2018.03.016 2018-04-01 Resolving the temperature profile in catalytic fixed bed reactors is essential for the investigation of reactions. However, this is not readily possible at laboratory scale without affecting the flow regime. Thermography tracks temperature profiles contactles...
Concurrent extraction of oil from roasted coffee (Coffea arabica) and fucoxanthin from brown seaweed (Saccharina japonica) using supercritical carbon dioxide 10.1016/j.jcou.2018.03.018 2018-03-30 The present study aimed to extract carotenoid from brown seaweed, Saccharina japonica (SJ) and oil from roasted coffee (RC) concurrently using supercritical carbon dioxide and evaluate its characteristics.

Pyrolyzing ZIF-8 to N-doped porous carbon facilitated by iron and potassium for CO2 hydrogenation to value-added hydrocarbons 10.1016/j.jcou.2018.03.015 2018-03-22 The iron-based catalysts derived from modified ZIF-8 were prepared, characterized, and applied to CO2 hydrogenation reaction. The addition of iron and iron/potassium evidently tuned the pyrolysis behavior by forming carbon encapsulated iron nanoparticles and ...
Prediction of solubility of N-alkanes in supercritical CO2 using RBF-ANN and MLP-ANN 10.1016/j.jcou.2018.03.008 2018-03-21 Recently, due to declination of oil production the importance of enhancement of oil recovery becomes highlighted. CO2 injection as one of popular approaches because of economically and environmental friendly has wide applications in enhancement of oil recover...
Continuous CO2 capture and reduction in one process: CO2 methanation over unpromoted and promoted Ni/ZrO2 10.1016/j.jcou.2018.03.013 2018-03-21 The recently demonstrated concept to combine CO2 capture and utilization in one process using isothermal unsteady-state operation, namely CO2 capture and reduction (CCR), was applied for CO2 methanation using unpromoted and K- or La-promoted Ni/ZrO2 catalysts...
Multicomponent Ni-CeO2 nanocatalysts for syngas production from CO2/CH4 mixtures 10.1016/j.jcou.2018.03.012 2018-03-20 The dry reforming of methane with CO2 is a common route to transform CO2/CH4 mixtures into added value syngas. Ni based catalysts are highly active for this goal but suffer from deactivation, as such promoters need to be introduced to counteract this, and imp...
Heteroatom self-doped activated biocarbons from fir bark and their excellent performance for carbon dioxide adsorption 10.1016/j.jcou.2018.03.014 2018-03-20 A series of cost-effective heteroatom-doped porous carbons has been developed from the agricultural by-products of fir bark by a two-step carbonization and activation process. The morphology, chemical characterization and texture properties were investigated ...
