Abstract: The mechanism of absorption of SO2 by ZnO slurry was investigated，and a novel indirect desulfurization process using ZnO slurry was proposed in order to avoid plugging. Based on experiments，the influence of slurry concentration，liquid-gas ratio，SO2 inlet concentration and superficial velocity on desulfurization efficiency was analyzed.
