A time-dependent mathematical model of a parallel-plate reactor was developed to study the electrochemical ̄uorination of organic compounds dissolved in anhydrous hydrogen ̄uoride. The model incorporates two-phase ̄ow with di€erential material, energy and pressure balances. Dynamic results are presented that show the e€ect of disturbances to the whole reactor or one of the cells of the multicell ...

Microbial electrochemical snorkel (MES) reactor is a simplified bioreactor based on microbial fuel cells (MFCs) and has been suggested to be a promising approach to solve many environmental problems. However, the microbial processes in MES reactors have not yet been characterized. This study shows that Shewanella decolorationis S12 can use the conductive snorkel as direct electron acceptor for ...

Electrohydrogenesis is a bio-electrochemical process where organic material is microbially oxidized to protons and electrons, which in turn are reduced to form hydrogen gas (H2). The reactor in which these reactions occur is termed a microbial electrolysis cell (MEC). The microorganisms that colonize the anode are known as electricigens and behave as biological catalysts, significantly reducing...

Electrochemical flow functionalization of alkenes is providing fast and easy access to dibromides or bromohydrins.

This paper deals with the design and the analysis of some nonlinear and adaptive control strategies capable to deal with the model uncertainties in an adaptive way for a complex and time varying bioprocess resulting from the association of a recycling bioreactor with an electrochemical reactor. The nonlinear controller design is based on the input-output linearizing technique. Computer simulati...

The continuous innovation in hydrogenation technology is testimony to its growing importance in the manufacture of specialty and fine chemicals. New developments in equipment, process intensification and catalysis represent major themes that have undergone recent advances. Developments in chiral catalysis, methods to support and fix homogeneous catalysts, novel reactor and mixing technology, hi...

A parametric systems model of the ATW [Accelerator Transmutation of (Nuclear) Waste] has been used to examine key system tradeoffs and design drivers on the basis of uni t cos ts . This model has been appl ied primarily to the aqueous-slurry blanket concept for an ATW that genera tes net -e lec t r ic power f rom the fissioning of spent reactor fuel. An important goal of this s tudy is the deve...

introduction             wastewater treatment using activated sludge process (asp) produces huge amounts of sludge that must be treated by efficient methods. wastewater sludge handling is one of the most important economic-technical challenges of wastewater treatment projects. conventional methods for this purpose are very time consuming, expensive and in lots of cases have limited success. in ...
