Abstract: Systems and methods are provided for upgrading catalytic slurry oil. The upgrading can be performed by deasphalting the catalytic slurry oil to form a deasphalted oil and a residual or rock fraction. The deasphalted oil can then be hydroprocessed to form an upgraded effluent that includes fuels boiling range products.

Abstract: The invention relates to hydrocarbon dehydrocyclization to produce products such as aromatic hydrocarbon, to equipment and materials useful for dehydrocyclization, to processes for carrying out dehydrocyclization, and to the use of dehydrocyclization for, e.g., natural gas upgrading. The dehydrocyclization is carried out in a catalytic reaction zone of a reverse-flow reactor.

Abstract: A single solvent method and machine for separating bitumen from oil sand ore are disclosed. The method includes the use of a single light paraffinic solvent, such as propane or butane as the agent to separate the bitumen from mined oil sand ore. Since light paraffinic solvents are vapors at atmospheric pressure and temperatures, the ore is placed in a pressurized container so that the solvent remains in a liquid state. When the container is pressurized, by the addition of the solvent itself, the liquid solvent is mixed with the ore to effect separation. The proposed machine settles more than 80% of the solids out under gravity in a modest period of time. The solvent-bitumen mixture is drained after the cleaning cycle, the container is depressured to a vapor recovery system and the remaining solids dumped out. The fine solids, drained with the liquids, are separated from the liquid mixture with relative ease by the use of current technology in other downstream equipment.

Abstract: The present invention relates to a method for preparing lubricating base oils by using vacuum distilled deasphalted oil, and more specifically, to a method for preparing various kinds of lubricating base oils by distilling a distillate obtained from a solvent deasphalting (SDA) process under reduced pressure to obtain heavy deasphalted oil (H-DAO) and light deasphalted (Lt-DAO) and then treating the H-DAO and the Lt-DAO by catalytic reactions, respectively. According to the present invention, it is possible to obtain heavy lubricating base oil (150BS) of a high viscosity grade which can not be obtained by a known catalytic reaction and a lubricating base oil of group III by hydrogenation, in a high yield, and thus economical efficiency is excellent.

Abstract: A process to prepare a heat transfer oil, comprising: a. dewaxing a substantially paraffinic wax feed by hydroisomerization dewaxing using a shape selective intermediate pore size molecular sieve under hydroisomerization conditions including a defined hydrogen to feed ratio, whereby a lubricating base oil is produced, b. selecting one or more fractions of the lubricating base oil having: i. a low pour point, ii. greater than 10 weight percent and less than 70 weight percent total molecules with cycloparaffinic functionality, wherein the one or more fractions have at least 31.2 wt % 1-unsaturations by FIMS, and iii. a ratio of weight percent molecules with monocycloparaffinic functionality to weight percent molecules with multicycloparaffinic functionality greater than 15; and c. blending the one or more fractions of the lubricating base oil with less than 0.2 wt % antifoam agent to prepare the heat transfer oil of a defined ISO viscosity grade.

Abstract: The present invention relates to a new crystalline zeolite SSZ-53 prepared by using phenylcycloalkylmethyl ammonium cations as structure directing agents.

Abstract: A compatibilizer and process for use in making crumb rubber modified asphalt. The compatibilizer causes the crumb rubber to completely interact with the asphalt, thereby improving the rheological properties of the asphalt and reducing the tendency of pavement made with the asphalt to ravel. The compatibilizer has as its reactive component one or more glycidyl groups; its polymeric backbone can be ethylenic, styrenic, or acrylic or ethylene vinyl acetate (EVA).

Abstract: The invention is a process of removing solids, particularly catalyst fines, from an asphaltene-containing hydrocarbon liquid. The process comprises contacting an asphaltene-containing hydrocarbon liquid with a solvent to create a mixture. The solvent is typically an alkane such as, propane to pentanes. Then, solids are removed from the mixture by any known process. Finally, additional solvent may be added, and the mixture heated until asphaltenes precipitate into a separate phase. The asphaltenes are removed from the mixture. The mixture is then further heated to recover the solvent from the deasphalted hydrocarbon liquid. The asphaltenes are advantageously gasified.

Abstract: The process permits to produce bitumens having a high penetration value by oxidation of base bitumens with small volumes of gaseous oxidizers, preferably air, at a temperature between 170.degree. and 250.degree., preferably 200.degree. C., by turbodispersion of the gaseous phase in the bituminous mass by means of a rapid turbodisperser.By adding appropriate fluxes and operating in the presence of catalysts, the technological characteristics of the end product can be varied until obtaining blends of bitumens that are adapted for new applications.The turbodisperser is provided with an impeller constituted by a plane disk carrying on its periphery a series of teeth made preferably with the active side located on the diameter of the impeller and the angle at the vertex greater than 45.degree..

Abstract: A clean pitch suitable for the manufacture of carbon artifacts is obtained by distilling from an aromatic feedstock a distillate material free from mesophase forming resins. The distillate is heated to obtain a heat soaked distillate free from mesophase but containing mesophase forming resins. The heat soaked distillate is further heated with inert gas sparging to convert it to mesophase pitch suitable for manufacturing carbon fibers. The heat soaked distillate also finds use as a binder or impregnation pitch.

Abstract: Asphaltenes and/or wax and/or water are removed from crude oil by contacting the crude oil with an organic solvent to dissolve the crude oil and precipitate asphaltenes and/or wax and separate the oil and water. Solvent is then separated from the deasphalted and/or dewaxed and/or dehydrated crude oil.Removing asphaltenes, wax and/or water reduces the viscosity of the crude oil and it can then be transported, e.g. by pumping through a pipeline, with less expenditure of energy.
