Co-site substitution by Mn supported on biomass-derived active carbon for enhancing magnesia desulfurization

Surface Modification of Cobalt‐Manganese Mixed Oxide and Its Application for Low‐Temperature Propane Catalytic Combustion

“…However, the temperature of peak β of xM-Co 3 Mn 1 (x > 0) had a tendency to move towards a higher position compared with that of 0 M-Co 3 Mn 1 , which was because the weak Co-OÀ Mn bond was broken due to the removal of Co and the reserving stronger Co-OÀ Mn bond represented a higher reduction temperature. [38] γ, δ and ε over xM-Co 3 Mn 1 (x > 0) was related to the conversion of Co 3 + to Co 2 + , which was consistent with the results obtained by XPS. [7,31] In fact, Catalytic combustion performance invoked related to the reaction of oxygen species and hydrogen at low temperature, so the hydrogen consumption of low-temperature region was invoked to estimate the reducibility of each catalyst.…”

Efficient deoxygenation of waste cooking oil over Co3O4–La2O3-doped activated carbon for the production of diesel-like fuel

“…[37][38][39] This is due to the synergistic effect between Co and La on the activated carbon surface. [40][41][42][43] However, excess Co dopant covers the active sites of La, and thus provides lower basicity. Consistent with this, a reduction in the distribution of basic sites (5292.06 mmol g À1 ) was found on the (Fig.…”

SO2 Absorption by Multiple Biomass Ash Types

“…Nevertheless, the reaction between SO 2 and sorbents is very complicated because of the complex mineral composition of biomass ash. There are other studies using biomass char or activated carbon prepared from biomass to remove SO 2 . , Biomass ash can be utilized for flue gas desulfurization because of its strong alkalinity, while rare studies on the direct use of biomass ash for desulfurization have been reported so far.…”
