The reactor performance of two novel fluidized bed membrane reactor configurations for hydrogen production with integrated CO2 capture by autothermal reforming of methane (experimentally investigated in Part 1) have been compared using a phenomenological reactor model over a wide range of operating conditions (temperature, pressure, H2O/CH4 ratio and membrane area). It was found that the methan...

Two membrane electrochemical reactors (MER) were designed and applied to HLADH-catalysed reduction of cyclohexanone to cyclohexanol. The regeneration of the cofactor NADH was ensured electrochemically, using either methyl viologen or a rhodium complex as electrochemical mediator. A semi-permeable membrane (dialysis or ultra-filtration) was integrated in the filter-press electrochemical reactor ...

The integration of mixed ionic electronic conducting (MIEC) membranes for air separation in a small-to-medium scale unit for H2 production (in the range of 650-850 Nm3/h) via auto-thermal reforming of methane has been investigated in the present study. Membranes based on mixed ionic electronic conducting oxides such as Ba0.5Sr0.5Co0.8Fe0.2O3-δ (BSCF) give sufficiently high oxygen fluxes at temp...

A new hybrid membrane-aerated biofilm reactor (MABR) technology that enables energy-neutral treatment of municipal wastewater is introduced. The process, which removes nitrogen using conventional nitrificationdenitrification, was demonstrated at pilot-scale, treating primary effluent. The new MABR membrane product can operate in a high mixed liquor suspended solids (MLSS) environment, making it...

Introduction An experimental study on the performance of a novel reactor system, termed the hybrid adsorbent-membrane reactor (HAMR) is described here. In the HAMR the reaction and membrane separation steps are coupled with adsorption. It was shown previously by our group that for esterification reactions this results in significantly improved performance. The focus in this presentation is on t...

Natural gas is becoming an increasingly important energy source, due to the increasing energy demands and declining oil reserves, whereas large volumes of natural gas are still widely available at remote locations. In view of the existing infrastructure for liquid fuels, natural gas is most efficiently used in the transport sector by converting it to liquid fuels via the Gas-To-Liquid process. ...

X $EVWUDFW In this study the partial oxidation of Q-butane to maleic anhydride (MA) in a solid electrolyte membrane reactor (SEMR) was investigated experimentally. The electrical conductivity of solid electrolyte membrane materials and vanadium phosphorus oxide (VPO) catalyst was investigated with 2-probe impedance spectroscopy. 13% yttria stabilized zirconia was selected as the solid electroly...

we evaluated the efficacy of a full-scale combined biophysicochemical system for treatingmolasses-based bioethanol wastewater in terms of organic substances, nutrient, and dark brown color removal. the main organic removal unit, i.e., the upflow anaerobic sludge blanket (uasb) reactor, achieved 80.7% removal and 4.3 nm3 methane production per cubic meter of wastewater with a hydraulic retention...
