| 20100320122 | MULTISTAGE RESID HYDROCRACKING - Processes for upgrading resid hydrocarbon feeds are disclosed. The upgrading processes may include: hydrocracking a resid in a first reaction stage to form a first stage effluent; hydrocracking a deasphalted oil fraction in a second reaction stage to form a second stage effluent; fractionating the first stage effluent and the second stage effluent to recover at least one distillate hydrocarbon fraction and a resid hydrocarbon fraction; feeding the resid hydrocarbon fraction to a solvent deasphalting unit to provide an asphaltene fraction and the deasphalted oil fraction. | 12-23-2010 |
| 20110139680 | PROCESS AND APPARATUS FOR INTEGRATION OF A HIGH-PRESSURE HYDROCONVERSION PROCESS AND A MEDIUM-PRESSURE MIDDLE DISTILLATE HYDROTREATMENT PROCESS, WHEREBY THE TWO PROCESSES ARE INDEPENDENT - The invention relates to the integration of a process for hydrotreatment of distillates (light and/or middle), that operates under a hydrogen partial pressure of 0.5 to 6.0 MPa, with a process for hydrotreatment/hydroconversion of middle and/or heavy distillates that operates at a hydrogen partial pressure that is at least 4.0 MPa higher than the hydrogen partial pressure of the process for hydrotreatment of distillates (light and/or middle). The integration resides in the use of the hydrogen-rich gas, obtained from the hydrotreatment/hydroconversion effluents, in the process for hydrotreatment of distillates (light and/or middle) and in the adjustment of the pressure level of this hydrogen-rich gas removed from the hydrotreatment/hydroconversion. This invention makes it possible to considerably reduce the net consumption of make-up hydrogen in the process for hydrotreatment of distillates (light and/or middle). | 06-16-2011 |
| 20110139681 | PROCESS FOR PRODUCING HYDROCARBON FUEL - Slurry hydrocracking a heavy hydrocarbon feed produces a HVGO stream and a pitch stream. At least a portion of the pitch stream is subjected to SDA to prepare a DAO stream low in metals. The DAO is blended with at least a portion of the HVGO stream to provide turbine or marine fuel with acceptable properties for combustion in gas turbines or for marine fuel grades. | 06-16-2011 |
| 20110139682 | CATALYST FOR UPGRADING INFERIOR ACID-CONTAINING CRUDE OIL, PROCESS FOR MANUFACTURING THE SAME, AND APPLICATION THEREOF - The present invention relates to a mesopore material of a catalyst for upgrading acid-containing crude oil. Said mesopore material is an amorphous material containing alkaline earth oxide, silica and alumina, and has an anhydrous chemical formula of (0-0.3)Na | 06-16-2011 |
| 20110233112 | IONIC LIQUID DESULFURIZATION PROCESS INCORPORATED IN A CONTACT VESSEL - Initial high sulfur levels of a hydrocarbon feedstock are reduced to desired low levels without the need for integration of substantial new equipment or hardware with existing hydroprocessing reactors. Ionic liquids are utilized as organic sulfur extraction agents and are added to and mixed with the hydrocarbon feedstock containing organosulfur compounds downstream of an existing cold separator vessel. The ionic liquid and hydrocarbon mixture is maintained in a contact vessel under conditions which promote the formation of ionic sulfur-containing derivatives that are soluble in the ionic liquid to be formed, thereby enabling extractive removal and separation of the organosulfur compounds from the feedstock. | 09-29-2011 |
| 20120061293 | RESIDUE CONVERSION PROCESS THAT INCLUDES A DEASPHALTING STAGE AND A HYDROCONVERSION STAGE - Conversion of a heavy hydrocarbon fraction that is obtained either from a crude oil or from the distillation of a crude oil and that has an initial boiling point of at least 300° C. by hydroconversion of at least one portion of heavy hydrocarbon fraction in the presence of hydrogen in at least one three-phase reactor containing at least one hydroconversion catalyst, separation of the effluent to obtain a light liquid fraction that boils at a temperature that is less than 300° C. and a heavy liquid fraction that boils at a temperature that is greater than 300° C., and a deasphalting of at least one portion of the heavy liquid fraction that boils at a temperature that is greater than 300° C. | 03-15-2012 |
| 20120261309 | PROCESS FOR THE CONVERSION OF HEAVY CHARGES SUCH AS HEAVY CRUDE OILS AND DISTILLATION RESIDUES - Process for the conversion of heavy charges such as heavy crude oils, tars from oil sands and distillation residues, by the combined use of the following three process units: hydroconversion with catalysts in slurry phase (HT), distillation or flash (D), deasphalting (SDA), characterized in that the three units operate on mixed streams consisting of fresh charge and recycled streams, by the use of the following steps:

| 20130075305 | SELECTIVE LIQUID-LIQUID EXTRACTION OF OXIDATIVE DESULFURIZATION REACTION PRODUCTS - The present invention provides selective extraction of sulfoxides, or sulfoxides in combination with sulfones, from hydrocarbon mixtures containing these compounds. A significant advantage of the invention is that oxidation products resulting from oxidative desulfurization of hydrocarbon feedstocks are selectively extracted with minimum co-extraction of non-oxidized products such as valuable hydrocarbon fuel components. | 03-28-2013 |
| 20130161237 | HYDROPROCESSING OF HEAVY HYDROCARBON FEEDS - Heavy oil feeds are hydroprocessed in the presence of a solvent under conditions that provide a variety of benefits. The solvent can be an added solvent or a portion of the liquid effluent from hydroprocessing. The processes allow for lower pressure processing of heavy oil feeds for extended processing times or extended catalyst lifetimes be reducing or mitigating the amount of coke formation on the hydroprocessing catalyst. | 06-27-2013 |
| 20130319911 | METHOD FOR CONVERTING HYDROCARBON FEEDSTOCK COMPRISING A SHALE OIL BY HYDROCONVERSION IN AN EBULLATING BED, FRACTIONATION BY ATMOSPHERIC DISTILLATION AND LIQUID/LIQUID EXTRACTION OF THE HEAVY FRACTION - Method for converting hydrocarbon feedstock comprising a shale oil, comprising a step of hydroconverting in an ebullating bed, a step of fractionating by atmospheric distillation into a light fraction, a naphtha fraction, a gas-oil fraction and a fraction heavier than the gas-oil fraction, a step of liquid/liquid extraction of the fraction heavier than the gas-oil fraction, and a dedicated hydrotreating for each of the naphtha and gas-oil fractions. The method aims to maximize the yield of fuel bases. | 12-05-2013 |

| 20160130511 | PROCESSES FOR RECOVERING HYDROCARBONS FROM A DRAG STREAM FROM A SLURRY HYDROCRACKER - A process for recovering hydrocarbons from a slurry hydrocracking reactor. The hydrocarbons are recovered by taking a drag stream of the slurry in the reactor. After separating lighter hydrocarbons in a separation zone, the heavier hydrocarbons can be processed in a deashing zone, with a vacuum column bottoms from a separation of the effluent stream recovered from the reactor. The deashing zone can recover the heavier hydrocarbons in a deashed pitch. Additionally, a VGO rich stream from the deashing zone may be recycled back to the reactor. | 05-12-2016 |
