  • Method for continuous thermal cracking of heavy petroleum oil
    Patent number: 4443328
    Abstract: Disclosed herein is an improved method for continuous thermal cracking of heavy petroleum oil, which can achieve a high degree of cracking in a column-like reactor of relatively small size and provides residual pitch rich in .beta.-resin components and lean in gas mixed therein. The above method comprises charging preheated heavy oil into an upper reaction zone of an upright cylindrical continuous reactor, which is divided into upper and lower reaction zones by means of a partition plate, drawing the resultant cracked gas and oil vapor from the upper reaction zone, and discharging residual pitch through the bottom of the lower reaction zone.
