Catalytic oxidation of organic pollutants in wastewaters

Objectif

Development of new and improved processes for wastewater treatments is needed to increase the amount of re-use of water at industrial sites. This can be achieved with the emerging new technology of wet air oxidation (WAO), which consists of oxidising into CO2, solutions or suspensions of organic pollutants in water. This methodology is particularly well adapted to high concentrated and toxic effluents of chemical, paper pulp, textile, and other industries, and to recycle the treated water in the industrial process. However, to be competitive the operating cost has to be improved by decreasing the temperature and pressure of oxidation treatment, which can be achieved by employing oxidation catalysts.

The main objective of this project is to optimise new, efficient heterogeneous oxidation catalysts for treating water solutions of organic molecules containing N-, Cl-, or S-heteroatoms, representative of industrial waste waters.

Two innovative types of catalysts will be prepared, characterised and tested in oxidation reactions:
(i) Oxides or hydroxides of first row transition metals prepared by proprietary methods, which are active and stable under oxidative reaction conditions (Task 1);
(ii) Platinum group metals on new forms of supporting materials: glass fiber cloths and activated carbon cloths, which are well suited to improve mass transfer of reactants, thus improving the oxidation activity (Task 2).

The second objective is to identify the intermediate oxidation products and to determine the kinetic of elementary reaction steps (Task 3), using advanced analysis and kinetic methodologies. This study is needed to understand the reaction mechanism, and kinetic aspects are useful input for process development.
With the most successful catalysts identified in Tasks 1 and 2, and from the mechanistic and kinetic studies of Task 3, the ultimate objective is to develop an efficient oxidation process (Task 4), e.g. reduce by 80% the total organic carbon content of organic pollutants under low temperatures (80-120°C) and pressures (1-10 bar).

To achieve these objectives a consortium of four research teams from INTAS and NIS countries are associated in the project. They all have a recognised expertise in the field of water depollution by catalytic oxidation; the interest of putting them together is that they have complementary skills, equipment and tasks.
This complementarity is required to achieve the work programme which has been divided into four tasks corresponding to the objectives given above.
Partner CR1 (Professor V. N. Parmon, Boreskov Institute, Novosibirsk) will be responsible for Tasks 1 and 3 with the help of partner CR3 (Professor B.M. Laskin, Applied Chemistry, St.-Petersburg). Partner CR2 (Professor M. Sheintuch, Technion-IIT, Israel) will be responsible for Task 2. In addition to the co-ordination task, partner CO (Dr P. Gallezot, CNRS, France), will be responsible for Task 4, e.g. the development of an innovative catalytic wet air oxidation process.
Exchange of catalysts, analytical methods, and information on reaction kinetics are planned, together with exchange of scientists and co-ordination meetings, to ensure an efficient collaboration between the four teams. Annual reports will be provided and mid-term assessment is planned to re-orient the research if required.

The pre-competitive research involved in this project is ultimately aimed at preparing future, more industrially oriented RTD project.
