This work, entitled "La déshydrogénation oxydante du propane en propène sur le système Bi-P-V-O massique et supporté" (Oxidative dehydrogenation of propane to propene on a mass-supported Bi-P-V-O system), was carried out in collaboration between the LCCA Laboratory of Coordination and Analytical Chemistry, Faculty of Science, Chouaib Doukkali University, El Jadida, and the LACCO Laboratory of Catalysis in Organic Chemistry, POITIERS.It is composed of five chapters as follows:o Chapter 1: A bibliographical study of the propane oxydehydrogenation reaction.o Chapter 2: Description of the experimental techniques used to characterize the catalysts prepared.o Chapter 3: Preparations, characterizations and reactivities of BiP1-xVxO4 bulk catalysts.o Chapter 4: Oxidative dehydrogenation of propane on titanium-supported catalysts.o Chapter 5: oxidative dehydrogenation of propane on silica-supported catalysts.

This work, entitled "SYNTHESIS, CHARACTERIZATION AND CATALYTIC BEHAVIOR OF V2O5 AND Ni-Mo CATALYSTS SUPPORTED ON COPPER ORTHOPHOSPHATE Cu3(PO4)2 ", was carried out at the Laboratory of Catalysis Chemistry and Corrosion of Materials (LCCM), Faculty of Science, Chouaib Doukkali University, El Jadida. It consists of five chapters as follows:Chapter 1: Bibliographical study of the research background Chapter 2: Experimental techniques Chapter 3: Synthesis, characterization and catalytic behavior of copper orthophosphate Chapter 4: Synthesis, characterization and catalytic behavior of V2O5 catalysts supported on copper orthophosphate (CuP) Chapter 5: Synthesis and characterization of Ni-Mo catalysts catalytic behavior supported on copper orthophosphate (CuP ). Our objective was the co-precipitation synthesis of copper phosphates, chosen as reference materials for depositing active phases such as vanadium oxide V2O5 and nickel molybdenum oxide NiMoO.
