摘要/Abstract

摘要： Dust removal from pyrolytic vapors at high temperatures is an obstacle to the industrialization of the coal pyrolysis process. In this work, a granular bed with expanded perlites as filtration media was designed and integrated into a 10 t·d^-1 coal pyrolysis facility. The testing results showed that around 97.56% dust collection efficiency was achieved. As a result, dust content in tar was significantly lowered. The pressure drop of the granular bed maintained in the range of 356 Pa to 489 Pa. The dust size in the effluent after filtration exhibited a bimodal distribution, which was attributed to the heterogeneity of the dust components. The effects of filtration bed on pyrolytic product yields were also discussed. A modified filtration model based on the macroscopic phenomenological theory was proposed to describe the performance of the granular bed. The computation results were well agreed with the experimental data.
