- 1 - SPECIFICATION Title of the Invention CONTINUOUS THERMAL CRACKING METHOD OF HEAVY PETROLEUM OIL Abstract of the Disclosure The specification describes a method for producing thermally-cracked products of high quality such as gas, cracked light oil and pitch by continuously subjecting heavy petroleum oil to thermal cracking in a single- column reactor. More specifically, heavy petroleum oil, which has been heated in a heating furnace to a temperature of a predetermined range, is continuously charged into the lowermost reaction zone of a column-like reactor which is vertically divided into a plurality of reaction zones by means of at least one partition wall defining an opening therethrough to make said reaction zones to communicate with one another. The heavy petroleum oil is subjected in the reactor to thermal cracking while maintaining its temperature, pressure and residence time in the reactor within their respective predetermined ranges and causing oil, which has been treated in each of said reaction zones, to be successively transferred to its upper reaction zone together with bubbles under stirring conditions. Then, the thus-cracked product is continuously discharged from the uppermost reaction zone of the reactor.
