CATALYTIC COMBUSTION OF TOLUENE ON Pd-Cu/SiO2 CATALYSTS

Catalytic combustion of toluene on silica supported Pd, Pd-Cu and Cu catalysts has been investigated. The solids were prepared by the impregnation method and they were characterized by evaluation of surface area, metal dispersion and surface composition. The reaction was studied under stoichiometric...
