FIELD: petroleum processing and manufacture of building materials.
SUBSTANCE: method concerns manufacture of building materials via processing refinery wastes, namely bitumen binder from refinery sludge, subjected to neutralization followed by thermal oxidation of neutralized products with air oxygen. Method is characterized by that thermal oxidation is conducted in presence of elementary sulfur and modifying additive used in amount of 5-15% based on the weight of feed to be oxidized.
EFFECT: enhanced process efficiency.
