摘要/Abstract

摘要： 在利用固体吸附剂进行CO₂捕集系统中,为了降低反应器的压降和提高吸附剂利用率,提出两种新型的斜向紧凑微流化床(oblique compact micro fluidized beds, OCMFB)和纵向紧凑微流化床(vertical compact micro fluidized beds, VCMFB或CMFB)反应器。通过装载固体吸附剂,通过捕集体积分数为0.5%的CO₂对两种反应器的性能进行研究,并与传统径向流固定床(radial flow fixed bed, RFFB)反应器进行对比。试验结果表明:由于吸附剂在OCMFB和CMFB中处于流化态,在RFFB中处于静态,从而得到OCMFB反应器压降为CMFB反应器的82%,与RFFB反应器相比压降降幅为14%~323%;CMFB反应器的CO₂吸附穿透时间为OCMFB反应器的109%,与RFFB反应器相比增幅为44%。经过10次CO₂捕集循环,与RFFB反应器相比,OCMFB和CMFB反应器的吸附剂磨损相当,但CO₂吸附性能更稳定。

Abstract: In order to reduce pressure drop and improve adsorbent utilization in the CO₂ capture system using solid adsorbents, a novel oblique and vertical compact micro fluidized beds(OCMFB and CMFB)reactors were proposed. The performance of the OCMFB and CMFB reactors for CO₂ capture when the volume fraction of CO₂ is 0.5% using solid adsorbents were experimentally studied and compared to that of the radial flow fixed bed(RFFB)reactor. The results showed that the pressure drop in the OCMFB reactor was 82% of that in the CMFB reactor, reduced by 14%~323% compared to the RFFB reactor; the breakthrough time for CO₂ adsorption in the CMFB reactor was 109% of that in the OCMFB reactor, increased by 44% compared to the RFFB reactor due to the fluidization of the adsorbents in the OCMFB and CMFB reactors other than the statics in the RFFB reactor. The attrition of the adsorbents in both OCMFB and CMFB reactors were equal to that in the RFFB reactor, but the adsorption capacity for CO₂ in both OCMFB and CMFB reactors were more stable than that in the RFFB reactor after 10 cycles of CO₂ capture.
