The effects of different parameters on the hydrodynamics of trickle bed reactors were discussed for Newtonian and non-Newtonian foaming systems. The varying parameters are varying liquid velocities, gas flow velocities and surface tension. The range for gas velocity is particularly large, thanks to the use of dense gas to simulate very high pressure conditions. This data bank has been used to c...

Agricultural wastewater is a major source of herbicides, which pose environmental and health concerns owing to their substantial use poor elimination rate in conventional treatment plants. White-rot fungi are versatile degrading xenobiotics; however, the key problem encountered with application actual scenarios competition indigenous microorganisms, mainly bacteria. To address this barrier, two...

Trickle bed reactor was used to study the hydrogenation of nitrobenzene over Ni/SiO2 catalyst. The catalyst prepared using Highly Dispersed Catalyst (HDC) technique. Porous silica particles (capped cylinders, 6x5.5 mm) were as support. characterized by TPR, BET surface area and pore volume, X-ray diffraction, Raman Spectra. trickle packed with diluted fine glass beads in order decrease external...

A three-phase nonisothermal heterogeneous model for describing the hydrotreating reactions in a trickle-bed reactor with complete catalyst wetting was solved. It includes correlations for determining solubility data, mass-transfer coefficients, and properties of the compounds under operating conditions. The model, based on the two-film theory and mass-transfer resistance at the gas-liquid and l...

Biomethane constitutes an important biofuel for the transition towards a biobased circular economy with sustainable energy sector. An environmentally friendly pathway its production is through gasification of 2nd generation biomass that generates syngas (H2, CO, and CO2), followed by biomethanation. A novel design thermophilic trickle bed bioreactor was successfully tested at semi-pilot scale. ...
