PP-II-20PRODUCING OF THE SYNTHESIS-GAS AND FINE-POWDER SOOTIN THE MODIFIED REACTOR OF OXIDIZING PYROLYSIS BYTHE ELECTROCHEMICAL WAYHuseynova F.K.National Academy of Sciences of Azerbaijan, Institute of Chemical Problems,Farida_az@inbox.ruThe special reactor - ECCC (the electrochemical combustion chamber) and alsothe technique of acetylene producing in this device had been created and patentedfor the acetylene production by the incomplete oxidation of natural gas method withimposition of diffusive discharge on the reacting space /1/. This method is topical stillpresent because of the target product output on this device reached14-15 % (forcomparison: output С 2 Н 2 on used now industrial units are only 7-9 %).The basic characteristics of this process in the reactor ECCC is modifiedpyrolysis of a mixture of natural gas and oxygen with oxidizer surplus factor α ≤0.4,pressure 0.98·105 Pa, with diffusive discharge imposition on reacting space atvoltage between electrodes 400 - 800 V, and maximum of the reactions temperaturechanges between 1400-2800°K.Process is complex multi-parameters one because there are participate from 10 to14 reactions in its kinetics scheme; it is depend from the chosen version of parameters.For management of such complex process with 16 operating parameters, itsmathematical model had been work up with considering all features of experimentsimplemented ECCC design. The model had been identified on the base ofthermodynamic and kinetic calculations very precisely /2, 3/ and had allowed to make anexplanation and clearance of instability of some modes chosen during experiments (afire torch attenuation, products very much burning, the reactor breakdown, etc.) /4/.After the mathematical model identification by means of spent experiments andverifying it is completely adequate to process, the theoretical optimization of the processwas been made with the goal to study all opportunities of this device and process. Duringthe optimization of process it has been describes theoretically the acetylene output canreach 25 % if the adequate heat resisting material for reactor made would be found. Andthe reached in experiments output 14.75 % is maximal for a used material /5/.At the analysis consist of the real pyrogas (produced at experiments) and, in the further,data of the process theoretical optimization and calculating experiments for various processparameters had been noticed that except for acetylene which was an initial target product,other valuable products exist in the pyrogas structure that can become independent targetsand products owing to its demand in a science and in the modern industry.At first stage during experiments these products had been displeased sincecomplicated the ECCC experiments course and operating conditions selection.
