Effective removal of paracetamol in compound parabolic collectors and fixed bed reactors under natural sunlight

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 ...

24 Fixed Film Stationary Bed and Fluidized Bed Reactors

Effect of backwashing on perchlorate removal in fixed bed biofilm reactors.

The influence of backwashing on biological perchlorate reduction was evaluated in two laboratory scale fixed bed biofilm reactors using 1- or 3-mm glass beads as support media. Influent perchlorate concentrations were 50 microg/L and acetate was added as the electron donor at a concentration of 2 mg C/L. Perchlorate removal was evaluated at various influent dissolved oxygen (DO) concentrations....

Steam reforming of propane over Ni-K/CeO2-Al2O3 catalyst in fluidized- and fixed-bed reactors under low steam to propane ratio

Fluidized bed was employed to investigate propane steam reforming over Ni-K/CeO2-Al2O3 catalyst. The catalyst was characterized by XRD, SEM, TG/DTA, and N2 adsorption-desorption tests. Effects of promoters, space velocity, temperature, and steam/propane (S/C) ratio on propane conversion, H2 yield, H2/CO ratio, and stability were studied and discussed. The experiments were carried out under cond...
