PROCESS OF PRODUCTION OF FLUID PRODUCTS FROM HEAVY PETROLEUM PRODUCTS Russian patent published in 1994 - IPC

FIELD: petroleum industry. SUBSTANCE: fluid products are produced by thermal cracking at 400-440 C for the course of 0.5-12 h. Feedstock is mixed in advance with combustible shale or with sapromixite taken in the amount of 8-25 per cent by mass ground to 500 μm by portions so that quantity of first portion of combustible shales or sapromixite amounted to 20-65 per cent of their total amount to produce homogenized suspension. Thermal cracking of suspension is conducted continuously under pressure of 3-8 MPa or under periodic condition under pressure of 6-12 MPa. EFFECT: increased output of fluid products. 2 cl, 1 tbl
