-A pilot plant study on propane catalytic combustion in a membrane reactor with separate reactant feeds is presented. The membrane consisted of a porous alumina tube activated by insertion into its pores of a Pt/7-A1203 catalyst. The role of reactants concentration and of the feed flow rates were studied in the transport-controlled operating regime, where a number of interesting properties of t...

Nowadays, hydrogen and methanol are attractive prospects because of lower emission compared to the other energy sources and their special application in fuel cell technology, which are now widely regarded as key energy solution for the 21st century. These two chemicals also can be utilized in transportation, distributed heat and power generation and energy storage systems. In this study, a nove...

hospital wastewater has special importance since having pathogens, radioactive materials, pharmaceutical wastes and heavy metals. removing them into environment without any treatment may cause serious problems for the public health. membrane biological reactor is the combination of the activated sludge and membrane filters. this research has investigated the performance of the nano-filtration i...

Carbon membrane can be produced using a wide variety of polymer precursor materials via heat treatment process. A general concept route of precursor selection-preparation-modification-performance analysis platform for the carbon membrane has been proposed to promote the development of carbon membrane material for a wide range of application. The current review considers the recent progress of c...

One of the technologies for Pre-Combustion Decarbonisation is the production of hydrogen rich fuel gas from fossil fuel feed stock by means of a water gas shift membrane reactor system. A study to develop and test hydrogen selective membranes for use in a water gas shift membrane reactor operating with sour synthesis gas has been sponsored by the CO2 Capture Project. The aim of the project was ...

The coupling of reactions in catalytic membrane reactors provides novel reactor configurations that allow shifting the thermodynamic equilibrium and yields of thermodynamically limited reactions and enhancing significantly the rate of production. An interesting pair to couple is the dehydrogenation of ethylbenzene to styrene and the hydrogenation of nitrobenzene to aniline. Hydrogen produced in...

The partial oxidation of methane to synthesis gas was investigated in a novel type of perm selective membrane reactor using Perowskite hollow fibers. The operating behaviour of this membrane reactor integrating the process steps selective separation of oxygen from air, selective O2 transfer in the membrane and oxidation of methane with simultaneous steam reforming was investigated theoretically...

A study has been conducted to investigate the effect of loading rates on membrane fouling in a moving bed biofilm membrane reactor process for municipal wastewater treatment, especially analysing the fate of submicron colloidal particles and their influence on membrane fouling. Two operating conditions defined as low and high organic loading rates were tested where the development and fate of t...

An electrocatalytic membrane reactor assembled using a nano-MnO2 loading microporous Ti membrane as an anode and a tubular stainless steel as a cathode was used to oxidize n-propanol to produce propionic acid. The high efficiency and selectivity obtained is related to the synergistic effect between the reaction and separation in the reactor.
