Thermal cracking apparatus for hydrocarbonaceous materials of high molecular weight

摘要

A thermal cracking apparatus for hydrocarbonaceous materials of high molecular weight, wherein an object hydrocarbonaceous material is subjected to thermal cracking in a fluid bed state, the product of said thermal cracking is separated into the overhead fraction and bottom fraction within a column, the resulting overhead fraction is further separated into a liquid-phase stream containing substantially no light component and a vapor-phase stream by means of a gas-liquid separator, and said bottom fraction is thermally cracked again by virtue of the combustion heat arising from combustion of said vapor-phase stream, whereby liquid-phase stream is recovered from the gas-liquid separator as a thermally cracked oil.
