ABSTRACT:
The viscosity of heavy oils is reduced in order to facilitate pipe line transportation thereof. A fraction of the heavy oil is deasphalted in the presence of C.sub.5 -C.sub.7 hydrocarbons, a portion of the separated asphalt is converted to synthesis gas, at least a portion of said gas is used to manufacture an alcohol mixture including methanol and C.sub.2 to C.sub.10 alcohols, which mixture is admixed with the heavy oil before transportation thereof. This procedure is more beneficial to the transported heavy oil than the prior processes which do not comprise the conversion of the asphalt fraction of the heavy oil.
