In this paper, the adsorption behaviour of activated carbon was investigated experimentally for changing butane concentration, temperature and relative humidity. Throughout the study, the coconut-based activated carbon was used. During the tests applied for butane concentration of 2, 4, 8, 20, 40 and 80 ppm, the temperature was taken as 15, 23 and 33 °C for a relative humidity of 50, 70 and 90%. The results showed that butane concentration had a direct relationship with adsorption. However, temperature and adsorption were inversely proportional. As a result of the adsorption between activated carbon and butane, it led to physical adsorption as one of the most important types of adsorption due to Van der Waals forces among molecules. To create physical adsorption, lower temperature ranges were more convenient. The relative humidity of the air reduced the time to reach the maximum saturation rate. The increased relative humidity also reduced the amount of butane adsorbed. Also, 50% relative humidity range was an important turning point. Relative humidity affected the adsorption of butane at a relative humidity of 50%. However, the relative humidity at 70 and 90% significantly reduced butane adsorption; on the other hand, it considerably increased the adsorption of moisture.

不同气体浓度、温度和相对湿度下椰子基活性炭吸附丁烷的实验研究

在本文中,活性炭的吸附行为在丁烷浓度、温度和相对湿度的变化下进行了实验研究。在整个研究中,使用了椰子基活性炭。在丁烷浓度为 2、4、8、20、40 和 80 ppm 的测试中,温度分别为 15、23 和 33 °C,相对湿度为 50%、70% 和 90%。结果表明,丁烷浓度与吸附量有直接关系。然而,温度和吸附量成反比。由于活性炭和丁烷之间的吸附,由于分子之间的范德华力,它导致物理吸附成为最重要的吸附类型之一。为了产生物理吸附,较低的温度范围更方便。空气的相对湿度减少了达到最大饱和率的时间。增加的相对湿度也减少了吸附的丁烷量。此外,50% 的相对湿度范围也是一个重要的转折点。相对湿度在 50% 的相对湿度下影响丁烷的吸附。然而,70% 和 90% 的相对湿度显着降低了丁烷吸附;另一方面,它大大增加了水分的吸附。
