DIESEL OIL WITH IMPROVED COMBUSTION PROPERTIES

摘要

This diesel fuel with improved combustion properties is prepared using a mixture of components A, B and C acquired by a combination of distillation and hydrodesulphurization, which form at least 70 % by weight of the ready fuel. Component A is a hydrocarbon distillate with a boiling point between 140 to 320 degrees C and sulphur content up to 0.45 % by weight, component B is a hydrocarbon fraction with a fractional range from 180 to 400 degrees C and sulphur content up to 0.2 % by weight, while component C is a petroleum distillate with fractional range of 181 to 420 degrees C and sulphur content up to 0.4 % by weight. The by-products are a hydrocarbon distillate with boiling point between 230 and 380 degrees C from hydrocracking, a refined product acquired by separation of n-alkanic hydrocarbons by adsorption on molecular sieves of the hydrocarbon fraction with distillation range from a range of temperatures of 140 to 320 degrees C and mixture of aromatic hydrocarbons with a boiling point over 140 degrees C.
