1. A method of performing hydrous pyrolysis on a sample of hydrocarbon source material for studying the kinetic parameters of hydrocarbons generated from said source material, comprising the steps of:

  • enclosing a measured amount of hydrocarbon source material in a sample holder closed at both ends by fluid permeable discs and sealing said sample holder in a pressure chamber of a reactor;

    sequentially charging said reactor with inert gas and evacuating said chamber to completely purge it of oxygen;

    at lease partially flooding said evacuated chamber with pure water;

    briefly evacuating said chamber to remove any remaining gases therefrom;

    heating said sample to a specified temperature for a specified period of time during which hydrocarbons generated by thermal maturation will be driven from said sample;

    transferring the water and more volatile generated hydrocarbons cryogenically into a transfer vessel which has also been purged of oxygen;

    recovering soluble bitumen and insoluble kerogen from said sample holder and chamber by washing;

    cryogenically recovering a first portion of said hydrocarbons from said transfer vessel; and

    recovering a remaining portion of said hydrocarbons by drying any residue materials remaining in said transfer vessel as a result of said cryogenic recovery step.
