FIELD: fuel distillates production. SUBSTANCE: residual petroleum raw materials mixed with sapropelite and with product of its liquid gasification (their quantities are by 2-10% each of residual petroleum raw materials mass) are affected by thermal cracking. The process is carried out at 390-490 C and pressure 3-8 MPa. Fuel distillates are isolated of cracking products. Portion of thus prepared diesel fraction may be recycled in raw materials mixture. Said portion is 10-20% of residual petroleum raw materials mixture. EFFECT: improves efficiency of the method. 3 cl, 1 tbl
