  • Patent number: 5307694
    Abstract: A sample holder for use in hydrous pyrolysis operations has a cylindrical member defining an axial throughbore with like discs of fluid permeable material at each end. One disc is fixed in the cylindrical member and the other removably attached for insertion of a sample into the holder. The holder has at least one end shaped so as to prevent sealing from occurring when the holder is placed in a test chamber.
    Type: Grant

    Inventors: David G. Nolte, Helen K. Haskin, Edwin L. Colling, Jr.
  • Patent number: 5180556
    Abstract: A method and apparatus for making a laboratory determination of the rate and type of hydrocarbon generated from a hydrocarbon source utilizes hydrous pyrolysis to generate hydrocarbons from the sample and then utilizes cryogenic methods to remove the fluid portions to a transfer vessel. The gaseous components are removed to a further vessel of known dimensions for determination of weight. The hydrocarbons in the transfer vessel are passed through a dryer to separate the water and their makeup determined. The hydrocarbons remaining in the reactor vessel are removed by working with solvents and their weights are determined after separation and evaporation of the solvents.

  • Patent number: 5135871
    Abstract: A method for isolating kerogen from a mineral sample in a pressurized reaction cell, which permits reaction at pressures greater than two atmospheres and provides for the removal of all liquids from the cell without significant loss of sample solids, employing multiple steps of addition and removal of concentrated hydrochloric acid, concentrated hydrofluoric acid, concentrated ammonium hydroxide, and deionized water.

  • Patent number: 5082787
    Abstract: A method for studying the rate and type of hydrocarbon generated from a hydrocarbon source utilizes hydrous pyrolysis to generate hydrocarbons from the sample and then utilizes cryogenic methods to remove the fluid portions to a transfer vessel. The gaseous components are removed to a further vessel of known dimensions for determination of weight. The hydrocarbons in the transfer vessel are passed through a dryer to separate the water and their makeup determined.

  • Patent number: 4865741
    Abstract: The invention is a method of group type separation of whole oils and bitumen by high performance liquid chromatography into fractions of asphaltenes, resins, aromatics, and saturated hydrocarbons. A multistep process is involved wherein the oil is initially solvated with a three part solvent mixture of methanol, acetone, and choroform. The solvated oil mixture is injected with a mobile phase into a cyano bonded phase column which will retain asphaltenes and resins, and pass through aromatics and saturated hydrocarbons. The unretained aromatics and saturated hydrocarbons are then injected into a silica column which will retain aromatics and pass through saturated hydrocarbons. Saturated hydrocarbons are recovered as they pass through the silica column. The resins, asphaltenes, and aromatics are recovered from the columns by a displacement material.

  • Patent number: 4415859
    Abstract: A paraffin monitor includes a pair of probes which are immersed in a medium having paraffin contained therein. A circuit is connected to the probes which provides an output voltage. The characteristics of the electric circuit changes over a period of time, causing a corresponding change in the voltage output, in accordance with a change in the amount of paraffin on the probes.
