<p>The present invention relates to the field of oil processing, in particular, to processing of heavy petroleum residues by non-catalytic thermal cracking to produce light petroleum, i.e. gasoline and diesel fractions and can be used in petroleum refining industry. A process for processing hydrocarbonaceous raw material includes a step of providing a high temperature stream of a heat transfer medium, a step of preheating the hydrocarbonaceous raw material to a temperature sufficient for pulverization of the raw material, and a step of feeding the high-temperature heat-transfer medium and the preheated hydrocarbonaceous raw material simultaneously into a reaction zone of a pyrolysis chamber, with subsequent quenching the reaction products, wherein the finely dispersed preheated raw material is fed into the reaction zone in the absence of oxygen and heated by the heat-transfer medium to a temperature of 700-850 °C at a heating rate (0,1-1) x10<5> degrees/ sec, so that the degradation of high molecular weight components occurs, the ratio of raw material / heat transfer medium being selected to provide further rapid decrease of temperature of the reaction mixture to 400-500 °C, thereby enabling synthesis of low molecular weight components.</p> |
