Experimental Study on Carbonation Treatment

摘要

The scope of Chinese medicine residue and utilization is relatively narrow, and the harmless processing technology needs to be systematized. Since its feasibility is still being questioned by people, this research discusses the properties of the Chinese medicine residue carbonation characteristics and designs the carbide single factor test and orthogonal test by combining with the Chinese medicine residue's carbonation characteristics. In this way, the most appropriate carbonation processing parameters are determined by the element analysis of raw materials and carbonation products, combined with the reduction rate and carbonation rate before and after carbonation. Therefore, the experimental results suggest that the most appropriate carbonation processing parameters occur at the carbonation temperature of 400°C when carbonation lasts 120 min.
