An on the fly fuel reformer device to produce variations in the autoignition and burning rate properties of a fuel by appropriate processing of some or all of a single fuel supply in its liquid form. The system includes a non-thermal plasma generator and/or a UV radiation source in contact with a fuel line so as to contact a multi-phase fuel in the line and dynamically modify the fuel to exhibit desired autoignition characteristics and burn rate such that the engine can operate with increased efficiency and lower emissions

Fuel oil compositions, and methods for blending such fuel oil compositions, to enhance initial compatibility and longer term stability when such fuel oil compositions are blended to meet IMO 2020 low sulfur fuel oil requirements (ISO 8217). In one or more embodiments, asphaltenic resid base stocks are blended with high aromatic slurry oil to facilitate initial compatibility such that low sulfur cutter stocks, e.g., vacuum gas oil and/or cycle oil, may be further blended therein to cut sulfur content while maintaining longer term stability. These fuel oil compositions are economically advantageous when used as marine low sulfur fuel oils because greater concentrations of high viscosity resids are present in the final blend.
