In the presented study, the sulfur dioxide sorption properties of fly ash zeolite X were investigated. Sorption tests were performed on fly ash zeolite samples that were not prepared specially for sorption, in addition to dried samples and samples in the presence of water vapor. The samples saturated with water vapor showed the highest sorption capacity. The sorption capacity of the samples additionally dried prior to the sorption experiment was higher than that of the samples that were not specially prepared for the sorption test. Regeneration tests indicated relatively good regeneration properties. The obtained results were described with the use of Langmuir, Sips, and Dubinin-Astakhov models, with the Dubinin-Astakhov model providing the best fit.
在本研究中，对粉煤灰X型沸石的二氧化硫吸附性能进行了研究。除了干燥样品和存在水蒸气的样品外，还对未专门为吸附制备的粉煤灰沸石样品进行了吸附试验。饱和水蒸气的样品显示出最高的吸附容量。在吸附实验前额外干燥的样品的吸附容量高于未专门为吸附试验制备的样品。再生试验表明其具有相对良好的再生性能。使用朗缪尔模型、西普斯模型和杜比宁-阿斯塔霍夫模型对所得结果进行了描述，其中杜比宁-阿斯塔霍夫模型拟合效果最佳。
