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.

Abstract: A petroleum derived oil is subjected to crude oil distillation or propane deasphalting to yield a viscous asphalt residue. The viscous asphalt residue is combined with an aqueous emulsifier comprising an EO-PO-EO block copolymer and passed through a mixer at 60.degree. C. to 70.degree. C. to form an emulsion. Criticality has been found in the amount of propylene oxide in the block copolymer and in the asphalt particle size. These emulsions are stable and can be transported by pumping through a pipeline. They are used as boiler fuel. They are also gasified with insufficient oxygen to produce synthesis gas.
