Many papers deal with the characterization of various sorption supports, tested with numerous contaminants. However, the results concerning the same “sorbate/sorbent” system are often very different. In sorption studies, there are regularly misleading calculations concerning (i) both kinetic and isothermal modeling by linear (instead of nonlinear) ...
Current industrial nitrogen fixation technology is unsustainable and has adverse environmental effects due to its reliance on fossil fuels. Using electricity-driven non-thermal plasma catalysis to fix nitrogen into NO3− is a promising solution, but the underlying mechanisms remain largely unknown. This study integrates a structured catalyst into a ...
An attempt was made for understanding the sorption behaviour of different actinide ions Pu4+, PuO22+, Am3+, Np4+, and NpO22+ on carbonate treated exhausted coffee powder (CTCP). Very efficient sorption of Pu4+ over other actinide ions from aqueous acidic medium was observed. Almost 4 h were required for achieving equilibrium. Experimental results f...
Extractive bioleaching is a range of technologies aiming at recovering metals contained in mineral resources using biological means. It was successfully implemented at the industrial scale and used either in the form of dump or heap treatments, or by using large-scale stirred tank reactors (STR). Recently, bioleaching is evolving towards the exploi...
An unconventional modelling methodology based on artificial neural networks is proposed to rapidly develop a model from data obtained during different batch experiments. The objective of the global model is to predict time evolution of concentrations of all species present in the reaction medium. For this, different recurrent neural networks are el...

Mimosa tannin has been used to produce two different types of carbons materials: hydrothermal carbon (HTC) on the one hand, and ordered mesoporous carbon (OMC) on the other hand. Both were obtained after pyrolysis at 1173 K, resulting in materials with similar BET areas, close to 580 m 2 /g, but very different pore size distributions (PSDs). HTC wa...

The objective of this paper is to present a model simulating and predicting the exchange kinetics of lead (Pb) between contaminated sediments and water during resuspension events potentially occurring in reservoirs. We developed an innovative model that combines thermodynamic speciation of particulate surfaces (oxides and Particulate Organic Carbon...

Ensiling of sugarcane trash (SCT) and sugarcane stalks (SCS) was studied to assess the effects of molasses (MOL) and lactic acid bacteria (LAB) inoculant on methane potential. The experiment was run for 70 days and monitoring parameters were analyzed at days 0, 5, 15 and 70. Biochemical methane potential (BMP) tests performed with fresh and ensiled...
In order to make 2nd-generation biofuels more competitive, high solid-matter content has to be reached. To progress towards this target, the mechanism for destructuring lignocellulose fibres in semidilute conditions has to be well understood, as this configuration shows the basic mechanism which limits transfers and efficiency. This study aims to d...
