Design of high effective catalysts with unique properties opens good perspectives for solving environmental problems of cleaning waste gas, particularly from toxic impurities of organic solvents.A new thermostable nanostructured composite materials based on shungyte was obtained and determined their adsorption capacity on the model substance o-xylene.Xylene used as a model substance is a part of the organic solvent presents in waste industrial gases.Best xylene sorbents (449.7 mg/g)-activated shungyte containing 70% carbon and saksaul charcoal (554.3 mg/g).Then polyoxide catalysts on the base of transition metals (Ni, Mn, Cu) modified by the rare earth elements (La, Ce and Nd), supported on a granular carrier were studied in the reaction of deep oxidation of o-xylene.100% activity showed 7.0% Cu-Mn-Ce-catalyst at T: 250-300 °C, C xylene : 0.6 g/m 3 , the optimum space velocity of gas-1,200 h -1 for catalysts supported on a granular carrier.The results obtained can be used in the purification of waste gas from paint, furniture, cable, printing and other enterprises from the impurities of toxic organic solvents.
