Combined use of O3/H2O2 and O3/Mn2+ in flotation of dairy wastewater [PDF]

open access: yes, 2018
This work investigated the degradation of organic matter present in synthetic dairy wastewater by the combination of ozonation (ozone (O 3 )/hydrogen peroxide (H 2 O 2 )) and catalytic ozonation (ozone (O 3 )/manganese (Mn 2+ )) associated with dispersed

"Memory loss" during mineral processing: Application to base metals traceability

open access: yes, 2013
International audienceTraceability of concentrates is required to introduce transparency in the trade of raw minerals. In this context traceability may be considered as a kind of inversion process: studying the product sold (i.e.

Wetting dynamics on lyophilic solid surfaces patterned by lyophobic islands

open access: yes, 2013
A theory for wetting of structured solid surfaces is developed, based on the delta-comb periodic potential. It possesses two matching parameters: the effective line tension and the friction coefficient on the three-phase contact line at the surface.

Study on the Synergistic Effects and Optimization of Flotation Reagent Blends Under Low Reagent Consumption

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Under low reagent dosage, the flotation performance of diesel as a collector was enhanced, and the synergistic mechanism of diesel blended with oleic acid and CTAB was investigated. Results showed that compared to pure diesel, the oleic acid blended system (Blend A) increased clean coal yield by 81.52% to 92.24%, while the CTAB blended system (

Methane Pyrolysis Performance in Catalytic Molten Media for Hydrogen Production From the Perspective of Bubble Column Reactor Design and Configuration

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In the hydrogen production routes from natural gas (methane), methane pyrolysis offers a cleaner option than the established steam methane reforming by producing CO2‐free hydrogen. However, in fixed bed reactors over solid catalysts, this technology experiences rapid catalyst deactivation due to carbon (coke) deposition encapsulating its ...
