Integrated Process for Partial Oxidation of Heavy Oil and In-situ Reduction of Red Mud

RM was used for the upgrading of vacuum residue (VR) by partial oxidation (POX). The function of diverse metal oxides in RM during VR upgrading was clarified and the utilization of used RM was developed. The results show that POX of VR with RM600 (calcined RM at 600 °C) decreases the cracking temperature, and increases heavy oil conversion and light fuels yield. The active sites Fe and O are highly dispersed on RM600, and Na species doping results in the formation of sodium ferrite, creating oxygen vacancy. Large specific surface area is remained after reaction due to the presence of Al2O3, SiO2 and TiO2. Fe2O3 in RM600 is in-situ reduced to Fe3O4, which could be further reduced by deposited coke on spent RM600 to produce Fe. The spent RM600 could be reused through a chemical looping POX and the yield of light fuels remains stable during 20 cycles.
