ABSTRACT:
A petroleum derived oil is subjected to propane deasphalting to yield a solid asphaltene residue. The residue is crushed to 425 micron diameter particle or less at a crushing temperature in the range of 77.degree. F. to 122.degree. F. The asphaltene particles are suspended in a residual petroleum oil emulsion. The resulting suspension comprises 5 wt % to 40 wt % asphaltene particles. The 40 wt % asphaltene suspensions are boiler fuel. The 5 wt % asphaltene suspensions are gasified with a deficit of oxygen to produce synthesis gas. The suspensions are stable and transportable by pumping through a pipeline.
