3D printed photopolymer derived carbon catalysts for enhanced wet peroxide oxid...
Silva, Adriano S.; Díaz de Tuesta, Jose Luis; Henrique, Adriano; Roman, Fernanda; Omralinov, Daria; Steldinger, Hendryk; Gläsel, JanIn this paper, we explore the application of powdered carbon and 3D-printed carbon monoliths prepared by carbonization of a tailored photopolymer. We demonstrate the efficiency of the developed carbonaceous samples in removing paracetamol (PCM) and sulfamethoxazole (SMX), used as model contaminants. Our results demonstrate that carbon samples are active in CWPO, and their catalytic activity is significantly imp...
Separation of n/iso-paraffins in a hierarchically structured 3D-printed porous ...
Henrique, Adriano; Zafanelli, Lucas F.A.S.; Aly, Ezzeldin; Steldinger, Hendryk; Gläsel, Jan; Rodrigues, Alírio; Etzold, Bastian J.M.; Silva, José A.C.Hierarchically structured 3D-printed porous carbons monoliths were investigated for their applicability in adsorptive n/iso-paraffin separation. Three materials of the same macroscopic shape were employed, which varied in the micro- and mesoporosity by altering the final CO2 activation step: non-activated and activated at 1133 K for 6 and 12 h, respectively. Chromatographic breakthrough experiments were conduct...
Separation of alkane isomers in a hierarchically structured 3D-printed porous c...
Henrique, Adriano; Steldinger, Hendryk; Díaz de Tuesta, Jose Luis; Glaesel, Jan; Rodrigues, Alírio; Gomes, Helder; Etzold, Bastian J.M.Hierarchically structured 3D printed porous carbons monoliths, exhibiting cylinder structures composed of tetragonal cubic centered unit cells, were studied for their applicability in adsorptive pentane (C5) and hexane (C6) alkane isomers separation (linear/branched). Three materials of the same macroscopic shape were employed in the study, which varied in the micro- and mesoporosity by changing the final CO2 a...
3D-printed activated carbon for post-combustion CO2 capture
Zafanelli, Lucas F.A.S.; Henrique, Adriano; Steldinger, Hendryk; Díaz de Tuesta, Jose Luis; Gläsel, Jan; Rodrigues, Alírio; Gomes, HelderThe applicability of 3D-printed activated carbons for their use to CO2 capture in post-combustion streams and the influence of activation conditions on CO2 uptake and CO2 to N2 selectivity were studied. For two monoliths with the same open cellular foam geometry but low and high burnoff during activation, a series of fixed-bed breakthrough adsorption experiments under typical post-combustion conditions, in a wi...
3D tuned porous carbon monolith as catalysts in the wet peroxide oxidation of p...
Roman, Fernanda; Steldinger, Hendryk; Díaz de Tuesta, Jose Luis; Henrique, Adriano; Silva, José A.C.; Gläsel, Jan; Etzold, Bastian J.M.; Gomes, HelderIn recent years, many pharmaceuticals have been identified at trace levels worldwide in the aquatic environment [1]. Municipal wastewater treatment plants (WWTPs) are considered the main sources of these pollutants as they are not generally prepared to deal with such complex substances and thus, they are usually ineffective in their removal [1]. Despite the low concentration of drugs contained in those effluent...
