Apparatus for pyrolysis of hydrocarbon starting products

摘要

An apparatus for pyrolysis of hydrocarbon starting products comprises a horizontally split casing for molten heat carrier. At least one injector having a nozzle for feeding hydrocarbon starting products to the casing and at least one pipe for removal of pyrolysis products are mounted in the upper part of the casing. The apparatus also has means for supplying heat to the heat carrier. According to the invention, the injector is mounted in such a manner that the outlet section of its nozzle is spaced apart from the surface of the heat carrier at a distance which is sufficient for the formation of a hydrodynamic crater in this surface under the action of a jet of hydrocarbon starting products flowing from the nozzle. Means for supplying heat to the heat carrier is arranged within the casing in such a manner that heat is supplied directly within the heat carrier. The invention enables the reduction of residence time of hydrocarbon starting products in the high-temperature zone and improvement of output of the pyrolysis process. In addition, the invention may be used for both low- and high-viscosity heat carriers. Due to the use of the invention, more lower olefins and aromatic hydrocarbons may be produced.
