THERMAL CRACKING OF FUEL OIL IN SLATE MIXTURE

The results of investigation of thermal cracking of fuel oil of Zhanazhol deposit in the mixture with bituminous slate are specified in this article to obtain motor fuels and raw materials for catalytic cracking. The dependence of light distillate fractional yield of slate concentration (3-12 wt. %), temperature (668-708 K) and time of thermal cracking are determined by the method of non-linear regression. According to the light distillate fractional yield, the following can be considered as optimal conditions of reaction: temperature 688 K, time of treatment 60 minutes and quantity if activating agent (slate) 9 wt. %. Total light distillate fractional yield under these conditions reaches 50.8 wt. %. The obtained light distillates of cracking contain moderate quantity of aromatic hydro- carbons (25.5-30.1 %), unsatisfied compounds (iodine value is equal to 1.5-3.9) and very small amount of sulphur (0.01-0.04 wt. %), that ensures compliance with modern requirements for gasoline and diesel fuels according to environmentally hazardous components.
