HEAVY HYDROCARBON STOCK HYDROCRACKING PROCESS Russian patent published in 2001 - IPC

FIELD: petroleum processing and petrochemistry. SUBSTANCE: hydrocracking process is effected by feeding into reaction zone hydrogen or hydrogen-containing gas in amounts 20-30% of the total weight of reactants, whereas gas pressure and temperature in chamber are adjusted to 10-35 MPa and 1300-1500 C, respectively. Into chamber with preheated hydrogen, hydrocarbon stock in amounts 70-80% of the total weight of reactants is loaded and mixed with hydrogen, cracking process being conducted at total hydrocarbon-hydrogen contact time 2 to 12 ms. Reaction products are then subjected to tempering at simultaneously reduced temperature and pressure over 5-10-ms time period and further separated. Following products are isolated: 42.266% gas products (methane, ethylene, ethane, propane, C4), 34,096% gasoline (C5- C12), and 17.284% diesel fuel, conversion achieving 98-99%. EFFECT: enhanced process efficiency. 3 cl, 1 dwg, 5 tbl
