摘要： A PROCESS FOR LIQUEFYING HYDROGEN, HELIUM AND NEON MORE EFFICIENTLY AND ECONOMICALLY THAN BY METHODS PREVIOUSLY PRACTICED, WHICH PROCESS INCLUDES THE STEPS OF COMPRESSING THE GAS (HYDROGEN, HELIUM OR NEON) TO A PRESSURE SUCH THAT, UPON ISOBARICALLY COOLING THE THUS COMPRESSED GAS, A TEMPERATURE ABOVE THE CRTITCAL TEMPERATURE OF THE GAS IS REACHED AT WHICH THE GAS CAN BE ISENTRIOPICALLY EXPANDED TO YIELD SUBSTANTIALLY A SINGLE LIQUID PHASE AT ATMOSPHERIC PRESSURE; THEN ISOBARICALLY COOLING THE GAS AT THIS PRESSURE TO SUCH TEMPERATURE; AND FINALLY ISENTROPICALLY EXPANDING THE GAS TO SUBSTANTIALLY ATMOSPHERIC PRESSURE THROUGH A WORK ENGINE.

摘要： This invention relates to the production of oils of specified higher quality at the same yield or to the production of a higher yield of oils of the same quality from a bituminous material by a combination of propane and pentane deasphalting than would otherwise be obtainable by utilizing either propane or pentane deasphalting processes alone. This is effected by subjecting the bituminous material first to a pentane deasphalting process to produce a light fraction containing resins and oils, followed by a propane deasphalting process on the resin-oil fraction previously obtained and the recycle of at least a portion of the resins fraction back to the pentane deasphalting process. Alternatively, this is effected by subjecting the bituminous material first to a propane deasphalting process to produce a heavy fraction containing asphaltenes and resins, followed by a pentane deasphalting process on the asphaltene-resin fraction previously obtained and recycle of at least a portion of the resins fraction back to the propane deasphalting process. The oil thus produced is obtained in higher quality at the same yield or in higher yield at the same quality by virtue of the ability to cut deeper into the residuum than otherwise would be possible.

摘要： Isotopically enriched helium-4, that is, helium-4 which is low in helium-3, is useful as a nuclear reactor coolant. It is produced from liquefied natural gas source helium by distilling helium-3 therefrom. The coolant is preferably enriched in hydrogen up to about 6 percent by volume to thereby improve the heat transfer characteristics of the coolant, and to reduce the power requirements for circulation of the coolant.

摘要： A process for producing additional liquid products from a heavy hydrocarbon material by vis-breaking of a separated asphaltene-containing fraction under controlled conditions of temperature and pressure. The asphaltene-containing fraction is obtained by contacting the heavy hydrocarbon material with a first solvent under elevated temperature and pressure conditions to separate the asphaltenes as a heavy phase from the remainder of the heavy hydrocarbon material. The products of the vis-breaking operation comprise distillable and substantially nondistillable liquid products in association with a residue including organometallic compounds. The distillable and substantially nondistillable liquid products then are separated from the residue. The distillable products can be separated by distillation. The nondistillable products are separated from the residue employing a second solvent maintained under elevated temperature and pressure conditions and then recovered as a liquid phase product.
