TL;DR: In this paper, the role of disodium oxalate as a dissolution enhancing agent for olivine is thoroughly examined through experiments in which all phases are carefully analyzed, and it is shown that under 20 bar of CO 2 pressure formation of strong oxalates-magnesium complexes in solution and precipitation of MgC 2 O 4 ·2H 2 O (glushinskite) impede any chance of obtaining significant amounts of magnesium carbonate.

TL;DR: In this article, local and average partial wetting efficiencies in trickle-beds have been directly measured by image processing and PIV analysis, and two different setups have been implemented: a vertical monolayer of pellets where the wetting structure and stability and also local velocity gradient are characterized by PIV, and a fixed bed to analyze (by photography) the axial evolution of wetting over bed cross section after a transient injection of dye.

TL;DR: In this article, the wet air oxidation of phenol over a commercial active carbon catalyst has been studied in laboratory-scale and pilot-plant fixed-bed reactors at mild temperatures and oxygen partial pressures of 120−160 °C and 0.05−0.2 MPa, respectively.

TL;DR: In this paper, the same activated carbon (AC) was shown to be stable and efficient at moderate temperature and oxygen pressure, such as that for phenol degradation, for the treatment of water that has been contaminated by 4-hydroxybenzoic acid.

TL;DR: In this paper, the competitive adsorption of phenol and p-hydroxybenzoic acid (4HBA) has been investigated on activated carbon (AC) for a wide range of concentrations under unbuffered conditions.
