Noble metal nanoparticle-loaded catalytic membrane reactors (CMRs) have emerged as a promising method for water decontamination. In this study, we proposed convenient and green strategy to prepare gold nanoparticle (Au NPs)-loaded CMRs. First, the redox-active substrate (CNT-MoS2) composed of carbon nanotube (CNT) molybdenum disulfide (MoS2) was prepared by an impregnation method. Water-diluted...

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...

Abstract Currently, thermophilic membrane biological reactors (TMBRs) are used to treat industrial wastewaters and sewage sludge with the aim of nutrients recovery. The performance process is strongly influenced by rheological behaviour (TBS) inside reactor. Considering high concentration heavy metals in matrices fed reactors, this work aims evaluate influence metal types on properties TBS. Slu...

Under proper operating conditions, a low dead volume continuous filtration module operated on biological broths (yeast and bacteria suspensions in stirred reactors) still fulfills the flow-rate requirements of an analytical apparatus (for example HPLC or FIA) without membrane regeneration. The filtrate stream has been successfully connected to a bioreactor in order to perform the automated HPLC...

A brief commentary on the three papers presented in the session on 'industrial processes' is presented. In particular, emphasis is placed on the factors considered to be crucial for an industrial process, namely: catalyst activity, the selectivity of the overall catalysed reaction and the lifetime over which the performance is observed. Control of selectivity is viewed as being most important, ...

Carbon molecular sieve membranes (CMSMs) are an important alternative for gas separation because of their ease of manufacture, high selectivity due to molecular sieve separation, and high permeance. The integration of separation by membranes and reaction in only one unit lead to a high degree of process integration/intensification, with associated benefits of increased energy, production effici...

Abstract Photocatalytic membranes reactors have become one of the most efficient technologies to treat polluted waters. However, a major drawback is unilateral irradiation membrane, where only side membrane exploited. To overcome this issue, we developed reactor can be irradiated on both sides. Polyacrylonitrile containing different amounts TiO 2 nanoparticles up 60% were first prepared by elec...

Trials on ciprofloxacin removal from real aqueous systems were performed using a photocatalytic membrane reactor with catalyst in suspension. Four sets of four treatment cycles carried out and experimental results processed the statistical point view order to assess reproducibility. Global efficiencies more than 99.85% obtained for all cycles. Coupling degradation process allowed separation reu...
