摘要:
为高效节能地利用固体吸附剂进行低浓度CO2捕集,提出了一种低压降和高吸附剂利用率的新型斜向紧凑微型流化床(OCMFB)反应器.通过CO2捕集实验,对OCMFB反应器与径向流固定床(RFFB)反应器、径向吸附器(RA)和流化床(FB)反应器的性能进行了对比研究.实验结果表明:与RFFB,RA和FB反应器相比,OCMFB反应器床道流化性和低进气速度的优势使压降最大降幅分别达到60%,56%和63%,CO2穿透吸附时间分别增加了42%,35%和8%,饱和时间分别缩短24%,20%和15%;经过10次CO2捕集循环后,OCMFB反应器与RFFB和RA反应器相比,吸附剂磨损基本相当,与FB反应器相比,吸附剂磨损明显减小;OCMFB反应器表现出比RFFB,RA和FB反应器更稳定的CO2吸附性能.
Abstract:
For efficient and cost-effective low-concentration CO2 capture using solid sorbents, a novel oblique compact micro fluidized bed(OCMFB)reactor with low pressure drop and high sorbent utilization was proposed. The performances of the OCMFB reactor, radial flow fixed bed(RFFB)reactor, radial adsorber(RA), and fluidized bed(FB)reactor for CO2 capture were evaluated and compared. The results show that compared with RFFB reactor, RA, and FB reactor, the OCMFB reactor can reduce pressure drop by 60%, 56%, and 63%, increase breakthrough adsorption time by 42%, 35%, and 8%, and reduce saturation adsorption time by 24%, 20%, and 15%, respectively, for CO2 capture due to the low inlet velocity and the fluidization of the beds. The attrition of the sorbents in the OCMFB is equal to that in RFFB reactor and RA, but much better than that in the FB reactor after 10 cycles of CO2 capture. The adsorption capacity of the sorbents in the OCMFB is more stable than that in RFFB reactor, RA, and FB reactor.
