The present invention is related to improvements in heavy crude oil and vacuum residues by applying a liquid ionic catalyst made of metals of the group VI B and VIII B of the Periodic Table. The catalyst is highly miscible in the hydrocarbon and is in a homogeneous phase therewith, the combination of different metals and the acidity provided by the protons that integrate the ionic liquid allowing the C-S, C-N and C-O bonds of resins and asphaltenes to be broken, the invention increasing the API gravity, reducing viscosity, removing sulphur and nitrogen compounds; in addition, from about 50% to about 70% of the hydrocarbons of the residue and heavy crude oil were transformed into lighter distillates.
