Hydrated sulphate minerals, including kieserite (MgSO4·H2O), gypsum (CaSO4·2H2O), and bassanite (CaSO4·~0.5H2O), have been detected on Mars (Gendrin et al., 2005; Wray et al., 2010), and polyhydrated ...
凹凸棒石是一种性能优良的吸附剂,对小分子极性气体具有很好的吸附性如SO2,H2S和NH3等。适当的热处理可以提高其脱除SO2的能力。文章采用热处理改性的凹凸棒石作为脱硫剂脱除烟气中的SO2,同时考察不同吸附温度下O2浓度和H2O含量对凹凸棒石烟气脱硫的影响。结果表明：在所考察的温度范围（50~200℃）内O2的存在没有影响凹凸棒石吸附SO2的吸附容量;当吸附温度低于100℃时,H2O与SO2存在竞...
