PP-II-20products became a mixture of hydrogen and carbon monoxide gases (CO + H 2 )named synthesis-gas and fine-powder soot C (which is condensed from gaseouscarbon) which turns during combustion of raw materials.By results of thermodynamic and kinetic calculations on mathematical model thegreater share in pyrogas have molecular hydrogen H 2 and carbonic monoxide CO,atomic carbon C. One of these products is topical now as fine-powder soot is actualproduct in the industry for producing ebonite, rubbers, some plastic masses, etc. Themixture of others is known as a synthesis-gas is the best alternative fuel for motortransport and only difficulties in its production are a delay for applying.The synthesis-gas is considered as alternative fuel as more relevant for using because ofreduction of explosion hazard of pure hydrogen is offered. As share of CO is approximately in3 times less than H 2 in the pyrogas it was offered to lead process optimization not on eachcomponent of this mix, and on synthesis-gas as a joint target product.By results of calculating experiments the maximal synthesis-gas output is possible60 volumetric % in structure of pyrogas in ECCC at various modes, but it is reached atgreater value of the enclosed enthalpy, than for an optimum output of acetylene,I =11.3 mln. J/kg СН4. Modes in which only 45-55 vol.% are most achieved and stable.Data of calculating experiments at which synthesis-gas output makes 30-35 vol. %have been obtained for α = 0.2 and enclosed enthalpy I = 9,5 mln. J/kg СН4.At kinetic process calculations energies of water and carbon condensations were notconsidered, though the caused by these processes anomalies were visible ontemperature curves. It has been made because of the sharp necessity in them is absentfor the adequate mathematical model determination, and because of authorsunwillingness complicated full enough process model much also with added parameters.Also the maximal soot output operating conditions parameters for laboratoryECCC achieved at specific enclosed enthalpy I = 15 mln. J/kg СН 4 , thus the sootoutput revealed 3-5 vol.%. This percentage is reached at the temperature peak 2300-2400°K. It means there is fuller pyrogas hydrocarbons combustion and certainly theacetylene share is insignificant, but it is not allow possible to set criterion function forboth products producing in one mode.REFERENCES[1].
