摘要

In this study, the HCl absorption performance of cheap natural soda ash loaded on a honeycomb support as a hot gas cleanup method was investigated by using flow-type fixed-bed reactor. The honeycomb-supported soda ash improved the HCl absorption extent significantly at the 1-ppm breakthrough time compared to the result without the support; thus, the use of the support was justified. The HCl removal performance of the honeycomb-supported soda ash depended significantly on temperature (300-600 degrees C). Under the present conditions, the absorption extent at 1-ppm breakthrough time was maximized at 500 degrees C. This absorption extent increased as the HCl concentration in the supplied gas decreased, and it was assumed that this absorbent was suited to actual coal gasification processes. No change in the HCl absorption extent (60-65 %) was observed for Na2CO3 loading between 33 and 65 mass%. The natural soda ash (Na2CO3) loaded on a honeycomb support changed to NaCl after HCl absorption examination. Regenerated HCl absorbent from spent honeycomb showed similar HCl absorption performance with fresh absorbent at 300-500 degrees C. (C) 2020 Institution of Chemical Engineers.
