<p>The invention relates to oil refining, in particular to a method for steam cracking of oil refined products, and can be used for the targeted processing of atmospheric vacuum distillation products and cracked products. The aim of the invention is to increase the yield of light diesel fraction of 160-360°C by converting the vapours of heavy petroleum products 340KK in lighter diesel fractions and to produce only the diesel fraction as a base commercial product. The inventive method for steam cracking of oil refined products involves heating feed stock vapours, wherein diesel-oil fractions or vacuum gasoils are used as a feed stock and the feed stock vapours are electrochemically heated by electric current at an excess pressure of 0.01-0.5MPa, a temperature of 300-450°C and in the presence of Al, Cr, Ni and Fe metal alloys which are used in the form of individual conductors situated in a vapour cracking area in contact with the flowing feed stock vapours, through which an electric current of 0.1-10 kV and 1-1·104 amperes passes.</p> |
