BACKGROUND Olive mill wastewater (OMW) is the aqueous effluent of olive oil producing processes. Given its high COD and content of phenols, it has to be decontaminated before being discharged. Anaerobic digestion is one of the most promising treatment process for such an effluent, as it combines high decontamination efficiency with methane production. The large scale anaerobic digestion of OMWs...

A feasibility study of a conventional fixed-bed reactor and packed-bed membrane (PBMR) in distributor configuration is carried out for the selective oxidation methanol to oxygenates dimethoxymethane methyl formate on VOx/TiO2 catalyst. Kinetic experiments provided reaction network reliable kinetic model six main reactions involved. The PBMR offers significant advantages potential formation both...

The isomerization of n-hexane to produce mono- and di-branched isomers is an important process for octane enhancement gasoline. In a fixed bed reactor, packed with MFI catalyst, there synergy between mixture adsorption equilibrium intra-crystalline diffusion. This best exploited by operating the reactor in transient manner, whereby desired products consisting branched can be recovered from exit...

Plasma-catalytic ammonia decomposition as a method for producing hydrogen was studied in packed-bed dielectric barrier discharge (DBD) reactor at ambient pressure and fixed plasma power. The influence of packing the zone with various materials, typically used catalyst supports, examined. At conditions (21 W, 75 Nml/min NH 3 ) where an conversion 5% achieved alone, improved found when introducin...
