A novel modified activated coke (AC) desulfurizer prepared by impregnation of metal oxides (Fe, Cu, Ni, Mn, Co), rare earth elements (Ce, La), and potassium hydroxide (KOH) was investigated. Experimental results showed that the desulfurization (DeSO2) efficiency of the ACKOH impregnation of Fe (Fe/ACKOH) was higher than other samples with impregnation of metal oxides at 120 °C and a space velocity...
