摘要: In this paper, the principles of airlift loop reactor in gas-liquid and gas-liquid-solid
systems are extended to gas-solid system. The models on bed average voidage in draft tube
and the particle circulation velocity in a gas-solid loop reactor are deduced. The
experiments are also conducted on a φ600mm×7000mm reactor. The catalyst voidage and
catalyst circulation velocity are measured at different radial and axial positions in draft
tube and annulus, respectively. The experimental data are analyzed systemically and
represented satisfactorily by the proposed models.
