Abstract: Dewaxed lube base stock oil which forms a wax haze on storage at a temperature above its cloud point is treated by contacting the oil and hydrogen with a zeolite catalyst such as ZSM-5 to eliminate the wax-haze formation. The method may be used to reclaim wax-contaminated lube base stock oils and other wax-contaminated hydrocarbon oils.

Abstract: A borehole logging tool includes a source of fast neutrons and a fast neutron detector. A discriminator connected to the detector rejects pulses from the detector attributable to nonsource neutrons from the formation and passes to a count rate meter those pulses from the detector attributable to source neutrons. The output of the count rate meter is recorded as a measure of neutron source output.

Abstract: A method and apparatus for measuring the concentration of a particular component, e.g. water, in a two-component mixture, e.g. water-oil. A probe having three sets of sensor electrodes is positioned into the mixture. A first elastic sac is secured over the exposed ends of a first set of electrodes and is filled with water. A second elastic sac is secured over the exposed ends of a second set of electrodes and is filled with oil. The ends of the third set of electrodes are left exposed. The electrodes are energized and each generate a signal representative of a measured electrical property, e.g. resistivity, conductivity, or capacitance, of the liquid in which they are immersed. By properly combining these three signals, the concentration of the particular component is determined.

Abstract: Dialkyl disulfide waste, such as that formed in a caustic wash process for removing mercaptans from a hydrocarbon stream, is converted to hydrogen sulfide and valuable hydrocarbons by catalytic contact with a highly siliceous zeolite catalyst exemplified by ZSM-5. The hydrogen sulfide in turn is readily converted to marketable sulfur, thus alleviating the waste disposal problem.

Abstract: This invention provides a method for converting waxy or viscous hydrocarbon oils to lower pour point or less viscous oils. By this method, reactive dispersions of zeolites, such as HZSM-5 crystals, are prepared with the oil to be converted, and conversion is effected by heating the dispersion.

Abstract: Process for reforming a hydrocarbon charge under reforming conditions in a reforming zone containing a sulfur-sensitive metal containing reforming catalyst wherein over-cracking of the charge stock and excessive temperature rise in the reforming zone is suppressed by pre-conditioning the catalyst, prior to contact with the charge, with a reformate of specified octane number and aromatics content.

Abstract: A process for the conversion of aromatic compounds to dialkylbenzene compounds rich in the 1,4-dialkylbenzene isomer. The reaction is carried out in the presence of a particular type of zeolite catalyst having a silica to alumina mole ratio of at least 12 and a constraint index of about 1-12, said catalyst having been modified by treatment with compounds of beryllium, and optionally phosphorus, to deposit a minor proportion of such elements on the zeolite.

Abstract: Water-soluble oxygenates of Fischer-Tropsch synthesis separated from water and acids are sequentially upgraded by a dehydration catalyst and a special zeolite catalyst to produce gasoline, LPG and light fuel oil.

Abstract: Hydrocarbon oils, especially waxy distillate lubricating oil stocks suitable for the preparation, by conventional unit processes, of high V.I., low pour point lubricating oils, are advantageously catalytically dewaxed with synthetic offretite catalyst preferably associated with a hydrogenation metal such as platinum or palladium.

Abstract: This invention provides an improved method for manufacturing a slate of lubricant base stocks from a paraffin base or a mixed base crude. In one embodiment of this invention, the bright stock raffinate is catalytically dewaxed with a catalyst comprising ZSM-5, for example, and the neutral oil raffinates are solvent dewaxed. The combined use of solvent and catalytic dewaxing as described herein provides a highly efficient method of manufacture without loss of product quality.

Abstract: Compounds of the formula ##STR1## wherein R is alkyl of 1 to 6 carbon atoms; R.sub.1 is an alkyl of 1 to 6 carbon atoms; and R.sub.2 is branched alkyl of 3 to 8 carbon atoms. These compounds are insecticides and nematocides.

Abstract: A process for the selective dimerization of cycloolefins having from 5 to about 12 carbon atoms is provided. The process comprises contacting of the olefin in the liquid phase with ZSM-12 at temperatures of 75.degree. to 400.degree. C.

Abstract: Method and apparatus for a condition-sensing system including features of checking the integrity of the system and detecting the presence of an alarm condition. Condition-sensing system is described as a fire alarm system for a central station employing a modification of the McCulloh circuit. A plurality of fire detection loops including normally open circuit detectors are each powered at opposite ends. Each leg of each loop is sequentially checked for integrity and then the detectors are checked for alarm conditions. A switching system is employed for the sequential operations. A programmable controller is disclosed as a switching system.

Abstract: Operation of regenerators of commercial equipment for catalytic cracking of hydrocarbon feedstock, such as gas oil, in the absence of added hydrogen is improved considerably by use of a cracking catalyst which contains a minute amount, as low as fractions of a part per million (ppm), of a metal from periods 5 and 6 of Group VIII of the Periodic Table or rhenium. These powerful dehydrogenation metals, in the amounts here used, do not have serious adverse effect on the cracking operation and reduce CO content of flue gases from the regenerator to negligible amounts.

Abstract: An improved process for selective cracking of 1,4-disubstituted aromatic compounds whereby the yield of recyclable olefin cracking product is increased. The process is carried out in the presence of a specified type of crystalline zeolite cracking catalyst (e.g. ZSM-5) and the reactor feed is admixed with ammonia or an organic amine.

Abstract: Provided herein is a novel method for generating TBP-distillation curves for crude petroleum oils, which curves are free of the large discontinuity in the raw data that is commonly observed when vacuum distillation is begun. The temperature-incremental volume data is accumulated up to a temperature equivalent to about 650.degree. F. at 760 mm. to provide a data bank. The data bank is then used to compute expected yield-temperature values up to a temperature equivalent of 850.degree. F. at 760 mm. The atmospheric residuum is then vacuum distilled and actual yield-temperature datum is compared with expected valves to obtain a deviation. The vacuum is then adjusted to reduce the deviation. Provided also is an automated apparatus for generating such curves.

Abstract: A system for predicting the octane number of a substantially olefin-free gasoline or gasoline component. A sample of reformed gasoline is analyzed by means of a gas chromatograph in order to ascertain the presence and amount of its constituents. Signals representing both the identities of the various constituents and their percent volume are applied to a computer which includes means for associating the constituents with predetermined groups and combining the relative volumes of the constituents of each group. Subsequent apparatus assigns predetermined coefficients to each of the groups, after which the volumes of each group are multiplied by the group coefficient. The resulting products are then summed to produce a first expression A. A second expression B comprises the summed differences between the product of the volume and octane number, and the product of the volume, octane number and coefficient, for each group.

Abstract: A method for treating oil-contaminated drill cuttings at an onsite location, e.g. offshore drillsite, whereby the cuttings can be disposed of directly without the risk of pollution. The contaminated cuttings are separated from the drilling mud and are mixed with a solid oil absorbent material which absorbs the free oil from the contaminated cuttings. A surfactant may be added to aid in binding the oil in the cuttings and the oil absorbent material. Where the cuttings are of large size, they are preferably ground before mixing them with the oil absorbent material. Further, where the mixture of cuttings may include small or dust-like particles, the mixture is compacted into pellets, briquettes or other masses having a sufficient density to sink in water.
