Fixed Bed Reactors for the Cultivation of Mammalian Cells: Design, Performance and Scale-Up

Fixed-bed reactors have gained growing attention for the cultivation of mammalian cells. They allow for a low shear stress cultivation of adherent and non-adherent cells due to the immobilization of cells within macroporous carriers. Their potential has been demonstrated for many cell culture purposes. Some of the recent developments are presented in this review, including improved antibody pro...

Computer aided design of pellets for fixed-bed reactors performing Michaelis-Menten reactions

The problem of designing the pellet characteristics for existing fixed-bed reactors has been studied. The reactor is assumed to be a unidimensional, plug-flow, heterogeneous type. Three particle shapes, two intraparticle mass transfer mechanisms, two kinds of film resistance to mass transfer and two poisoning patterns have been considered. An economic balance to both product market price and pe...

Creation of Pd/Al2O3 Catalyst by a Spray Process for Fixed Bed Reactors and Its Effective Removal of Aqueous Bromate

Palladium nanoparticles were grown on sub-millimeter activated Al2O3 particle support by spraying H2PdCl4 solution evenly onto the support, followed with a thermal reduction under H2 atmosphere. Compared with its counterpart created by the conventional impregnation method, the Pd/Al2O3 catalyst created by the spray process could enrich the existence of active Pd nanoparticles on the surface of ...
