Oil dispersed nickel-based catalyst for catalytic upgrading of heavy oil using supercritical water

[Display omitted] •Ni-stearate significantly improved heavy oil upgrading performance in SCW.•NinSm, NiO, and Ni(OH)2 were in-situ formed as electrocatalyst for water splitting.•These Ni compounds as catalysts promoted isomerization and hydrogenation.•Using catalyst significantly reduced asphaltenes...
