Khimach N. Methanol obtaining by synthesis gas conversion under conditions of mechanochemical activation of the catalyst

The conversion of synthesis gas to methanol at atmospheric pressure. Interpretation of influence features of mechanochemical activation of copper-zinc-alumina catalyst on the synthesis gas conversion to methanol. Catalytic and physicochemical properties of the copper-zinc-alumina catalyst SLM-U, which was performed for mechanochemical activation. The catalytic method of gas chromatographic control of the reactants and reaction products, X-ray diffraction, scanning electron microscopy, X-ray fluorescence analysis, argon thermal desorption. It were carried out the catalytic process of methanol synthesis from syngas conversion under the condition of mechanochemical activation of copper-zinc-alumina catalyst in the temperature range 160-260 ° C at atmospheric pressure. It was revealed that mechanochemical activation of copper-zinc-aluminum oxide catalyst can reduce reaction initiation temperature and synthesis temperature by 20-30 °C and increase productivity by 15-150 % due to the methods of mechanical activation. A new effective method for synthesis gas conversion into the methanol under conditions of mechanochemical activation of the catalyst can be used in industry as an alternative to methanol production at high pressures. It was worked out the design of experimental-industrial vibroreactor 20 m3 capacity and it will be tested in the condition of mechanochemacal activation of catalyst and pressure of 0,1-2.5 MPa. Field of application is petrochemistry and chemistry of coal.
