427-–448

In this review, research carried out on sorption-enhanced steam methane reforming (SESMR) process is presented and discussed. The reactor types employed to carry out this process, fixed packed bed and fluidized bed reactors, are characterized as well as their main operating conditions indicated. Also the concepts developed and investigations performed by the main research groups involved in the subject are summarized. Next the catalysts and CO2 sorbents developed to carry out SE-SMR are characterized and the relationships describing the reaction and sorption kinetics are collected. A general approach to model the process is presented as well as results obtained for a calculation example, which demonstrate the main properties of SE-SMR.

W pracy przedstawiono kompleksową analizę sposobów modelowania bioreaktora typu air-lift dla różnych struktur hydrodynamicznych przepływu mediów. Opracowano modele matematyczne bioreaktora dla tych struktur. Zaproponowano oraz przetestowano numeryczne sposoby wyznaczania pętli histercz stanów stacjonarnych i profili stężeń.

In the frames of this work a comprehensive analysis has been performed of the mathematical modelling of an airlift bioreactor for various hydrodynamic models of the media flowing through the reactor. For the structures of flow mentioned, mathematical models of the bioreactor have been elaborated. Numerical methods for determining the steady states hysteresis loops and profiles of concentrations in the bioreactor have been prepared and tested.
