CO2 Gasification of Densified Biomass: The Influence of K on Reaction Rate

Abstract The Boudouard reactivity of metallurgical coke and densified charcoals was investigated in this study. Potassium is known to accumulate ferromanganese furnaces hence evaluated as a catalyst CO 2 reactivity. Samples were impregnated using gaseous impregnation technique with K 3 .The experiments designed simulate conditions occurring an industrial furnace, used for production Mn-alloys. To find out the catalytic effect potassium, concentration varied from fraction percent up 5 wt.%. results show that increasing potassium content, charcoal increased, change more significant coke. reactivities much closer each other at highest content potassium. Scanning electron microscopy (SEM) energy dispersive x-ray spectroscopy (EDS) showed distributed on surface well deposited carbon particles formed charcoal.
