(a) relative proportions of flotate, sinkate and residue, (b) relative proportions of maltenes and asphaltenes in the flotate, (c) relative proportions of maltenes and asphaltenes in the residue, (d) Changes in saturate concentration for the experimental products expressed as saturates/(saturates + resins + asphaltenes) × 100. Aromatic hydrocarbons change little during aquathermolysis, consistent with published work12 and so have been excluded. (See the Supplementary Information for details).
