Partial oxidation of petroleum coke

Patent ·
OSTI ID:6587685
This patent describes a process for the partial oxidation of particulate petroleum coke substantially comprising carbon and containing a small amount of ash comprising vanadium constituents and other materials to produce in a gas generating zone a raw gaseous stream. The stream comprises hydrogen and carbon monoxide and contains entrained unconverted particulate petroleum coke comprising carbon and vanadium containing ash. The gaseous stream is cooled and scrubbed with water in gas cooling and scrubbing zones to produce a cooled and scrubbed clean gas stream and an aqueous dispersion of unconverted particulate petroleum coke. The improvement described here comprises: mixing the aqueous dispersion of unconverted particulate petroleum coke having a solids concentration in the range of about 0.5 to 20.0 weight percent and a particle size so that 100% passes through ASTM E11-70 Standard Sieve Designation in the range of about 37 microns to less than about 1700 microns with about 0.10 to 0.50 weight percent (basis weight of the aqueous dispersion of unreacted petroleum coke) of a vanadium collection agent.
