改性活性炭-甲醇工质对吸附性能的研究
Research on Adsorption Performance of Modified Activated Carbon-Methanol Pairs
摘要
Abstract
According to the environmental characteristics of the activated carbon in adsorption refrigeration system, some samples are prepared, and their characteristics, such as the pH, adsorption capacity and weight loss-rate are tested by experiments. The isotherm adsorption curves and TG-DTG (Thermal Gravity Differential thermal gravity)curves are obtained as well. The comparison of those data shows that, the adsorption performance of activated carbon-methanol will decrease after the samples are polluted by atmospheric dust or copper ions, as well as immersed in the high concentration acid or alkali solution; while the adsorption performance of activated carbon-methanol will increase after the samples are soaked in low concentration acid or alkali solution; distilled water has no effect on the adsorption performance of activated carbon-methanol. In addition, the thermal stability of the activated carbon will decline with atmospheric dust pollution and soak in acid or alkali solution.关键词
