Kamenskyh D. Alkylaromatic and heterocyclic hydrocarbons' hydrogenation on the composite proton conductive membrane catalysts

Processes hydrogenation alkylaromatic and heterocyclic hydrocarbons'. An establishment of laws of a course of processes hydrogenation alkylaromatic and heterocyclic hydrocarbons' on catalytic composite membrane. X-ray photoelectronic spectroscopy, X-ray spectral microanalysis, scanning electronic microscopy, infra-red spectroscopy, the element analysis, thermal desorbtion argon, measurement of proton conductivity of membranes at a constant pressure, gas chromatograph and X-ray-fluorescent methods of analysis of structure catalyst and initial reagents. The influence of the carbon polymer materials' additives on the hydrocracking industrial catalyst's catalytic activity has been determined. Has been shown that these additives (obtained on the base of the acetylene, carbamide and polyvinylchloride) possess the injected proton conductivity. There has been determined that 10 % polymer material's addition to the hydro cracking catalyst decreases the temperature of the catalyst activation on 100-150 ?C and increases the conversion of the feed stock in 1,5-2,5 times. There has been advanced the assumption that the added polymer promotes the acceleration of active hydrogen (as the proton) removal from the oxidation-reduction centers to the acidic-base catalyst's ones with new Bronsted centers' formation. The 10-fold increasing of the industrial catalyst's activity in the combination with the polymer additive in the proton stream owing to the ions' and hydrogen radicals' generation in the hydrogen medium is the experimental evidence of our contemplation. There has been carried out the method of the composite membranes catalysts' obtainment as the composition of the bi-functional catalyst and carbon polymer. By way of example of the model compound (isopropyl benzol, thiophen, furfural, khynolyne) there has been demonstrated the high activity of the developed membrane catalysts in the reactions of hydro cracking and hydro purification at 250-270 ?C temperatures and 4,0 MPa pressure. Sphere of the use is petrochemistry.
