Thermal upgrading of residual oil to light product and heavy residual fuel
Patent
·
OSTI ID:5374995
The method is described of upgrading residual oil boiling in the range of 1050/sup 0/F+ comprising: thermally cracking the residual oil at a temperature of 650/sup 0/-900/sup 0/F, a pressure of 0-100 psig, and a residence time of 0.1 to 5 hours at the highest severity in the range between about 1,000-18,000 seconds, as expressed in equivalent reaction time at 800/sup 0/F, sufficient to convert at least about 50 wt% of the residual oil to light products, substantially without the formation of solid coke; recovering separate fractions of light product and emulsifiable heavy bottom product which has a fusion temperature below about 150/sup 0/C and a quinoline-insoluble content between about 10 wt% and 30 wt% and wherein the highest severity is determined by a functional relationship between the asphaltene content of the residual oil feedstock and the heavy bottom product yield and quinoline-insoluble content.
