FIELD: petroleum chemistry, chemical technology.
SUBSTANCE: invention relates to a method for processing sludge. Method for processing sludge involves their treatment from sulfuric acid and thermal cracking carried out in the presence of gas-carrier in the mass ratio oil-like fraction : gas-carrier = 1:(0.05-0.1) at temperature 400-550°C. Nitrogen is used as a gar-carrier. Invention allows enhancing safety of the process and to form neutral medium that shows favorable effect on component composition of prepared liquid fuel.
EFFECT: improved processing method.
