Dehydrative condensation of β-aminoalcohols with CO2: An environmentally benign access to 2-oxazolidinone derivatives 10.1016/j.jcou.2018.03.020 2018-04-10 In this review, we try to provide a comprehensive and updated overview of recent developments in the synthesis of various 2-oxazolidinones through dehydrative condensation of easily available β-amino alcohols with carbon dioxide with special emphasis on the m...
Efficient cycloaddition of CO2 to epoxides using novel heterogeneous organocatalysts based on tetramethylguanidine-functionalized porous polyphenylenes 10.1016/j.jcou.2018.04.001 2018-04-09 The conversion of CO2 into cyclic carbonates by cycloaddition to epoxides is achieved under relatively mild reaction conditions (without solvent, 7 bar of CO2, 100 °C) using easily available heterogeneous tetramethylguanidine(TMG)-polyphenylene organocatalyst...
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. Response surface methodology was employed to determin...
Enhanced CO2 chemisorption at high temperatures via oxygen addition using (Fe, Cu or Ni)-containing sodium cobaltates as solid sorbents 10.1016/j.jcou.2018.03.019 2018-03-30 Sodium cobaltates containing Fe, Cu or Ni were synthesized, characterized and evaluated for CO2 capture at high temperatures. Initially, NaCoO2 and metal-containing samples were characterized by XRD, XPS, SEM and N2 adsorption-desorption, where it was probed ...
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 ...
