Abstract

本申请属于生物质资源高值化利用、绿色电化学工程与大气污染治理的交叉技术领域领域，涉及基于电热联合驱动的生物质精炼耦合含硫烟气脱硫制硫酸的连续系统及方法。该系统包括生物质转化与分离模块、电化学耦合反应与再生模块和烟气处理与硫酸浓缩模块。首先，含糖生物质原料与含I‑的酸性水溶液在加热及萃取剂存在下反应，生成含5‑甲基糠醛或其与糠醛的混合物的有机相和含I2和 / 或I3‑的酸性水相；随后，含I2和 / 或I3‑的酸性水相在电化学模块的阴极室被第一工作电极电催化还原，再生为I‑并返回生物质转化步骤循环使用；同时，烟气中的二氧化硫（SO2）和 / 或其水吸收态（SO32‑）在阳极室被第二工作电极电催化氧化为硫酸。
