Method for producing fuel distillates

摘要

The present invention relates to a method for producing fuel distillates used as raw material in the production of fuel for engine or jet engines. This invention essentially involves mixing residual petroleum raw material (oil fuel, tar) with sapropelite and with a fraction of thermo-cracking or hydro-cracking hydrogenated products having a boiling point of between 300 and 400 {C in an amount of between 1 and 5 % relative to the weight of said residual petroleum raw material. The mixture is then heated, homogenised at least twice in a dispersing agent at a temperature of between 85 and 105 {C, and submitted to a thermo-cracking or hydro-cracking process. The fuel distillates (petrol, diesel fuel and gas oil) are then separated from the thermo or hydro-cracking products. This invention pertains to the production of petroleum fuels and may be used in the oil-conversion industry.
