In this study, the effect of Ru and Gd promoters on 15Co/$$\gamma$$ γ -Al2O3 catalyst in the Fischer–Tropsch synthesis is investigated. The catalysts were synthesized by dry impregnation method and characterized by XRD, adsorption/desorption of nitrogen, TPR, TEM, ICP and XPS analyses. Activity and selectivity of the catalysts were examined in a fixed bed reactor at 210–230 °C with a H2/CO ratio of...
A novel mesoporous MCM-41 with remarkable wide channel diameters and thick walls was synthesized. The procedure involved the acid-catalyzed hydrolysis of tetraetheylorthosilicate (TEOS) in a water/ethanol/isopropoanol solvent mixture while employing 1-hexadecylamine as a templating agent and mesitylene as an auxiliary agent. After removal of the template by either extraction or calcination at 560 °C,...
