By making best use of the low value by-products and maximum utilization of the existed processing units to minimize the investment cost, several heavy oil upgrading processes have been developed and put into practice in China. For domestic sweet crude, RFCC combined with decanted oil coking or deasphalting have been selected. By RFCC-coking or deasphalting synergy, more poor quality feedstock can be accepted and needle coke and paving asphalt are produced. For imported sulfur crude, high vacuum distillation combined with asphalt production and combined coking with the use of coke in cement industry and Fluid Bed Combustion are recommend. v. 3, p. 243 CONGTP Long, Jun 9843 Deguang, Zu 9844 Research Institute of Petroleum Processing, SINOPEC 9845 World Petroleum Congress (16th. : 2000 jun. 11-15 : Calgary, Alberta, Canada) 34 Deguang, Zu 9844 Research Institute of Petroleum Processing, SINOPEC 9845 Long, Jun 9843 133548 133548 0 0 0 0 204467 BAAB BAAB CD W938 1 0013960 2026-03-04 200006040 0 CD W938 1 0013960 200006040 2026-03-04 14:03:22 2026-03-04 ARCHIVO
