AbstractThe use of a solid polymeric electrolyte, spe, is not commonly found in organic electrosynthesis despite its inherent advantages such as the possible elimination of the electrolyte entailing simpler purification processes, a smaller sized reactor and lower energetic costs. In order to test if it were possible to use a spe in industrial organic electrosynthesis, we studied the synthesis of 1-phenylethanol through the electrochemical hydrogenation of acetophenone using Pd/C 30% wt with different loadings as cathode and a hydrogen gas diffusion anode. A Polymer ElectrolyteMembrane Electrochemical Reactor, PEMER, with a fuel cell structure was chosen to carry out electrochemical reduction with a view to simplifying an industrial scale-up of the electrochemical process. We studied the influence of current density and cathode catalyst loading on this electroorganic synthesis. Selectivity for 1-phenylethanol was around 90% with only ethylbenzene and hydrogen detected as by-products.

ELECTROCHEMICAL TREATMENT OF WASTEWATER FROM ALMOND INDUSTRY USING DSA-TYPE ANODES: DIRECT CONNECTION TO A PV GENERATOR
ABSTRACTFood industries such as almond industry generate large volumes of wastewater in their processes and common techniques are not always efficient for treating this kind of effluents. In this work, the feasibility of a treatment for pollutants removal of a real industrial wastewater by electrochemical oxidation s studied at laboratory scale and then scaled-up to pre-industrial scale. The first stage of the work was performed at laboratory scale, using a 63 cm 2 cell, where different anodes (Ti/Pt, and DSA anodes (Ti/RuO 2 and Ti/IrO 2 )) and the optimal experimental conditions (pH, current density, temperature and In the second stage the scaling-up of the process from laboratory to pre-industrial scale was performed, by using a 3300cm 2 cell. The electrochemical reactor was finally powered by a photovoltaic generator directly connected, in order to operate by using a renewable energy and a COD elimination of 80 % was achieved.
