Zhongxiang Chen, Auteur ; John R. Grace, Auteur ; C. Jim Lim, Auteur |Thermodynamic analysis of CO2 capture and hydrogen production for steam methane reforming was carried out using ASPEN simulation software. The integrated reaction system is composed of a sorbent-enhanced fluidized bed reformer coupled with a flu[...]

Tingwen Li, Auteur ; Andrés Mahecha-Botero, Auteur ; John R. Grace, Auteur |The modeling and characterization of fluidized-bed reactors is challenging due to the variety of interrelated phenomena during the fluidization process. A key feature affecting gas−solid fluidized-bed reactors is the distribution of gas flow bet[...]

Yongmin Zhang, Auteur ; Chunxi Lu, Auteur ; John R. Grace, Auteur |The effect of louver baffles on gas back-mixing was investigated in a large-scale two-dimensional fluidized bed of fluid catalytic cracking (FCC) particles with helium as tracer gas. The axial gas dispersion coefficient of the baffle-free fluidi[...]

Gang Xiao, Auteur ; John R. Grace, Auteur ; C. Jim Lim, Auteur |Experiments were carried out with limestone particles of several narrow size intervals (125―180, 250―300, 355―425, 500―600, 600―710, 710―850, and 850―1037 μm) for times ranging from 0.5 to 144 h in a high-velocity jet apparatus to provide a more[...]

Mohammad A. Rakib, Auteur ; John R. Grace, Auteur ; C. Jim Lim, Auteur |A bubbling fluidized bed membrane reactor (FBMR) is modeled to estimate and predict the steam reforming of hydrocarbons. A two-phase fluidization model is used, with both the bubble and dense phases in plug flow. Diffusional mass transfer, as we[...]
