Carbon Energy, EarlyView.Replacing the oxygen evolution reaction with the electro‐oxidation of pollutants and waste streams offers an energy‐efficient route for simultaneous hydrogen production and pollutant remediation. This review summarizes the reaction mechanisms, catalyst design principles, and emerging paired‐electrolysis strategies that govern activity, selectivity ...

Chemistry – A European Journal, EarlyView.Newly developed polymers with intrinsic microporosity (PIMs) were combined with benzo[c][1,2,5]thiadiazole (BTZ) to be used as visible light photocatalytic coatings on the Vortex Fluidic Device (VFD). The VFD's rapid rotation and continuous flow capabilities enhanced singlet oxygen and superoxide radical reactions, achieving a dramatic eightfold ...

H2 production via ammonia decomposition in a catalytic membrane reactor [PDF]
Fuel Processing Technology, 2021 Publisher Copyright: © 2021 The AuthorsThe membrane reactor is proposed in this work as a system with high potential to efficiently recover the hydrogen (H2) stored in ammonia (NH3), which has been recently proposed as an alternative for H2 storage. With

The review covers the development of membrane reactor technologies at Degussa for the synthesis of fine chemicals. The operation of fed-batch or continuous biocatalytic processes in the enzyme membrane reactor (EMR) is well established at Degussa. Degussa has experience of running EMRs from laboratory gram scale up to a production scale of several ...

Modeling and simulation of membrane reactors and catalytic membrane reactors
2010Models of membrane reactors (MRs) and catalytic membranes are presented by taking into account the advantages of the separation provided by the membranes. In particular, a 1D mathematical model is presented for tubular reactors considering a cylindrical symmetry, which is modeled by first- or second-order differential equations depending on the ...

Membranes for Membrane Reactors
2011A membrane reactor is a device for simultaneously performing a reaction and a membrane-based separation in the same physical device. Therefore, the membrane not only plays the role of a separator, but also takes place in the reaction itself. This text covers, in detail, the preparation and characterisation of all types of membranes used in membranes ...

PHOTOCATALYTIC MEMBRANE REACTORS
2008Heterogeneous photocatalysis is a promising technique for the abatement of organic and inorganic pollutants. This method is based on particular properties of semiconductor materials that irradiated with light of suitable energy (i.e. equal or higher than that of the band gap) can promote electrons from the valence to the conduction band with the ...
