Title: | Titania-loaded coal char as catalyst in oxidation of styrene with aqueous hydrogen peroxide | Authors: | Nurhadi, M. Chandren, S. Yuan, L.S. Ho, C.S. Indra Mahlia, T.M. Nur, H. |
Issue Date: | 2017 | Journal: | Titania-loaded coal char as catalyst in oxidation of styrene with aqueous hydrogen peroxide. International Journal of Chemical Reactor Engineering, 15(1), 45-5 | Abstract: | Titania-loaded coal char catalyst was successfully prepared. The preparation steps involved pyrolysis of low rank coal at different temperatures and durations, sulfonation, impregnation of titanium(IV) isopropoxide, and then heating at 110°C. It is found that the coal chars' surfaces were rough after sulfonation and impregnation, while large pore volume, high surface area and carbon composition were observed at low pyrolysis temperature for short duration. These properties contributed to high selectivity towards benzaldehyde (> 90%) at 600°C (0.5-2 h)) in styrene oxidation using aqueous hydrogen peroxide as the oxidant. © 2017 by De Gruyter 2017. | DOI: | 10.1515/ijcre-2016-0088 |
