Abstract
Carbon black and hydrogen chloride are produced by treating with chlorine the products resulting from the cracking of heavy hydrocarbon oils in the vapour phase in the presence of hydrogen chloride. Crude petroleum is vaporized in a heated silica cylinder together with hydrogen chloride and passed to a cracking chamber, the products, with or without the separation of some of the constituents, being caused to react with chlorine in the manner described in Specification 317,165, [Class 1 (ii), Inorganic compounds, other than &c.]. The carbon black so removed and a quantity of hydrogen chloride equivalent to the chlorine used is separated and may be treated as described in Specification 343,676 to regenerate the chlorine, the excess of hydrogen chloride being returned to the cracking process. The cracking temperature is 600 to 700 DEG C., the pressure may be atmospheric and an excess of hydrogen chloride, e.g. five times the volume of hydrocarbon vapour, may be employed, the process being continuous. Less than the theoretical amount of chlorine may be used, hydrocarbons in excess being returned to the cracking stage.
