本文以纸张为碳基体,PVC为活性氯前驱体,利用两者热交互作用制备含氯吸附剂,研究了不同温度、不同混合比例、不同气氛、不同停留时间下热解制备的吸附剂的汞脱除效果。实验表明,纸张与PVC有很明显的交互作用,从而在吸附剂表面形成活性Cl原子。原料中PVC的加入明显增强了吸附剂的吸附性能,在110℃和150℃下对汞的吸附性能显著提高,且在150℃下,CO_2比N_2气氛下制备的吸附剂吸附性能更好。研究表明废弃物衍生汞吸附剂是一种可行的方案。
In this paper, paper as the carbon matrix, PVC as the active chlorine precursor, the use of both the thermal interaction of chlorine-containing adsorbents, studied at different temperatures, different mixing ratio, different atmosphere, different residence time pyrolysis prepared mercury Removal effect. Experiments show that there is a clear interaction between paper and PVC to form active Cl atoms on the adsorbent surface. Addition of PVC in the raw materials significantly enhances the adsorption performance of the adsorbent. The adsorption properties of mercury at 110 ℃ and 150 ℃ are significantly increased, and the adsorbent performance of the adsorbent prepared at 150 ℃ is better than that under the atmosphere of N_2. Research shows that waste derived mercury sorbent is a viable option.
