A packed-bed membrane reactor in a distributor configuration is studied theoretically for the oxidative propane dehydrogenation and compared with fixed-bed reactor. Based on detailed 2D models considering two different heat mass transport scale-up including various reactor-to-particle diameter ratios (D/dP) analyzed respect to performance, transfer hot spot formation. Higher selectivities at lo...

Reactor design considerations are crucial aspects of dark fermentative hydrogen production. During the last decades, many types of reactors have been developed and used in order to drive biohydrogen technology towards practicality and economical-feasibility. In general, the ultimate aim is to improve the key features of the process, namely the H2 yields and generation rates. Among the various c...

Cavitation damage to membranes is a major barrier for developing an ultrasound (US)-assisted membrane water treatment process. In this study, US was integrated heterogeneous Fenton reactor the of pharmaceutical-containing with aims i) fouling control, ii) enhancement oxidation. order prevent damages due cavitation, stable and violent cavitation regions were identified by quantification analysis...

The Kamioka Liquid scintillator Anti-Neutrino Detector (KamLAND) is collecting antineutrino events generated by nuclear reactors and by Thorium and Uranium decay in the Earth interior. We comment on a systematic approach to the evaluation of the geo-neutrino contribution and of its uncertainties in KamLAND, taking into account geophysical and geochemical indications, estimates, and data. The re...
