低灰活性炭的SO2吸附特性受某些过渡金属衍生物的存在和气体吸附混合物的组成的强烈影响;特别是，氧气和水蒸气的影响非常重要。在SO2吸附-解吸循环中，这些负载的碳（模拟它们在真实的脱硫过程中的应用），吸附活性的碳基质的减少似乎强烈减少在SO2的存在下，特别是当H2O也存在。此外，钒和铁的存在特别增强了这种效果。这可能与这些元素在SO2氧化过程中的催化活性有关。
The SO2adsorption characteristics of low ash active carbons are strongly influenced by the presence of certain transition metal derivatives and by the composition of the gaseous sorption mixture; in particular, the effect of oxygen and water vapour is very important. In the SO2sorption–desorption cycles on these supported carbons (simulating their application in a real desulphurisation process) the decrease of sorption activity of the carbon matrix appears to be strongly reduced in the presence of SO2, especially when H2O is also present. Moreover, the presence of vanadium and iron particularly enhances this effect. This is probably related to the catalytic activity of these elements in the SO2oxidation process.
