2Ca(OH)2SpoutedbedIn the present study, the carbonation reaction of hydrated lime in semi-dry condition is investigated experimentally in a laboratory-scale spouted bed reactor. Results show that for operating conditions where the concentration of CO2 is low, the capture efficiency is raised by ...
例子:Fe, Au, Co, Br, C, O, N, F。 离子电荷尚未得到支持,将被忽略。 替换不可改变的组以避免歧义。例如,C6H5C2H5 + O2 = C6H5OH + CO2 + H2O不能被平衡,但XC2H5 + O2 = XOH + CO2 + H2O可以。 不需要复合状态[如(s)(aq)或(g)]。 你可以用小括号()或括号[ ]。
Balance the reaction of Ca + (OH)2 + CO2 = CaCO3 + H2O using this chemical equation balancer!

It has been found that the presence of CO2 does have an effect on the desulfurization reaction and on the consumption of desulfurizing agent when Ca(OH)2 is employed as the sorbent for SO2. Also, the formation of CaCO3 is inevitable at about 70 °C and is enhanced under conditions of ...
so3和ca(oh)2反应的化学方程式In the reaction between sulfur trioxide (SO3) and calcium hydroxide (Ca(OH)2), a double displacement reaction takes place, resulting in the formation of calcium sulfate (CaSO4) and water (H2O). The balanced chemical equation for this reaction is represented as ...
The carbonation of Ca(OH)2 as shown in reaction 2 was believed to impose the greatest limitation on the hydrate's ability to react with SO2 because carbon dioxide (CO2) was very abundant, the carbonate formed was thought to be non-reactive, and the reaction consumed porosity. Wang2 showed...
This case is in agreement with the formation of a dense non-porous layer of carbonate mineral around the core of the reacting Ca(OH)2 particles, thereby limiting the transfer of CO2. Finally, an alternative reaction mechanism is proposed for the gas–solid carbonation of CaO, when the ...
It is also noteworthy, that the abundance of calcite indicates high activity of CO2 during metasomatic processes, whereas the formation of secondary titanite could be triggered by the release of Ca2+ and Ti4+ during the breakdown of pyroxene and magnetite/ilmenite, following such reaction as: $$...
