Method for producing fuel distillates

Abstract

The invention relates to the production of fuel distillates and may be utilized in the oil refining industry for the production of motor fuels and jet engine fuels. The idea of the invention is that residual oil stock (fuel oil, tar oil, petroleum tailings) is mixed with a slate coal having the mineral part content of 45-60% by weight and the organic part content of 40-55% by weight and with the shale oil fraction, having the hydrogen content not less than 10.0% by weight, in the amount of 1.0-6.0% of the raw stock, then the resulting mixture is homogenized in a mixer at a temperature not lower than 80° C., and thermal conversion or hydrocracking is carried out. Fuel distillates (gasoline, diesel fuel, vacuum gas oil) are extracted from the products of thermal conversion or hydrocracking.

What is claimed is:  
     
         1 . The method for producing fuel distillates, including the mixing of residual oil stock with ground sapropelite and a liquid activating additive, homogenization and thermal conversion or hydrocracking of the resulting mixture with the subsequent extraction of the desired products, characterized in that said ground sapropelite is, prior to homogenization, mechanically and chemically activated in, at least, one disperser, a slate coal containing the mineral part in the amount of 45-60% by weight and the organic part in the amount of 40-55% by weight is used as said sapropelite, shale oil fraction with the boil-off limits of 200-400° C. and the hydrogen content not less than 10.0% by weight is used as the liquid activating additive, said slate coal and shale oil fraction being taken, counting on raw stock, in the quantity of 1.0-5.0% by weight and 1.0-6.0% by weight, respectively.  
     
     
         2 . The method according to  claim 1 , characterized in that slate coals are used that contain, grams per ton: molybdenum 3-15, nickel 20-35, cobalt 3-10, chrome 30-40, copper 15-40 and lead 5-20.
