1. A method of extracting hydrocarbon-containing organic matter from a hydrocarbon-containing material using a homogenous one-phase hydrocarbon-extracting liquid consisting essentially of a turpentine liquid, comprising the steps of:

  • contacting the hydrocarbon-containing material with a homogenous one-phase hydrocarbon-extracting liquid consisting essentially of a turpentine liquid to form a homogeneous one-phase extraction mixture and a residual material, the homogeneous one-phase extraction mixture comprising at least a portion of the hydrocarbon-containing organic matter extracted into the turpentine liquid, the residual material comprising at least a portion of non-soluble material from the hydrocarbon-containing material that are not soluble in the turpentine liquid;

    separating the extraction mixture from the residual material; and

    separating the extraction mixture into a first portion and a second portion, the first portion of the extraction mixture comprising a hydrocarbon product stream comprising at least a portion of the hydrocarbon-containing organic matter, the second portion of the extraction mixture comprising at least a portion of the turpentine liquid.
