FUEL COMPOSITION AND A METHOD OF ITS PRODUCTION Russian patent published in 2005 - IPC

FIELD: petrochemical industry; fuel compositions and methods of their production on the basis of petroleum heavy fractions.

SUBSTANCE: the invention is pertaining to fuel compositions and methods of their production on the basis of petroleum heavy fractions, and also to utilization of oily wastes and by-products of petrochemical industry. The fuel composition contains 1-7 % of recovered oil products, 3-9 % of the heavy gas oil of a catalytic cracking or the heavy gas oil of the time-lagged carbonization, or the heavy pyrolized resin, or a vat residue of production of butyl alcohols, and the rest - the residual fuel oil. The composition is produced by a premixing of 10-70 % of recovered oil products with 30-90 % of the heavy gas oil of the catalytic cracking or heavy gas oil of a time-lagged carbonization, or the heavy resin, or the vat residue of production of butyl alcohols at the temperature of 20-70°C. The received mix is then commixed with the residual fuel oil at the temperature of 25-50°C with production of a quantitative structure of the above-stated fuel composition. Realization of the given invention allows to produce a stable fuel composition, to effectively utilize the recovered oil products, to use as stabilizers of the fuel mixture the available products of a petroleum and petrochemical rerefining, to reduce power inputs, to improve an air medium ecology, to obtain an economic effect at the expense of utilization of the oily wastes and by-products of oil refining and petrochemical industry and production of additional volumes of the residual fuel oil.

EFFECT: the invention ensures production of a stable fuel composition, effective utilization of the recovered oil products, use of the available products of a petroleum and petrochemical rerefining as stabilizers of the fuel mixture, reduced power inputs, improved ecology, an economic efficiency.
