Patent number: 10399913Abstract: In a process for upgrading paraffins and olefins, a first feed comprising C14? olefins is contacted with an oligomerization catalyst in a first reaction zone under conditions effective for oligomerization of olefins to higher molecular weight hydrocarbons. Deactivated catalyst is removed from the first reaction zone at a first temperature and is contacted with an oxygen-containing gas and a hydrocarbon-containing fuel in a regeneration zone to regenerate the catalyst and raise the temperature of the catalyst to a second, higher temperature. A second feed comprising C14? paraffins is contacted with the regenerated catalyst in a second reaction zone to convert at least some of the paraffins in the second feed to a reaction effluent comprising olefins, aromatic hydrocarbons and regenerated catalyst; and the reaction effluent is supplied to the first reaction zone. A system for performing such a process and a product of such a process are also provided.Type: GrantFiled: December 12, 2018Date of Patent: September 3, 2019Assignee: ExxonMobil Research and Engineering CompanyInventors: Mohsen N. Harandi, John Dusseault

Patent number: 10400177Abstract: Systems and methods are provided for integrating a fluidized coking process, optionally a coke gasification process, and processes for production of additional liquid products from the coking and/or gasification process. In some aspects, the integrated processes can allow for conversion of olefins generated during a fluidized coking process to form additional liquid products. Additionally or alternately, in some aspects the integrated processes can allow for separation of syngas from the flue gas/fuel gas generated by a gasifier integrated with a fluidized coking process. This syngas can then be used to form methanol, which can then be converted in a methanol conversion process to form heavier products. In such aspects, olefins generated during the fluidized coking process can be added to the methanol conversion process to improve the yield.Type: GrantFiled: November 14, 2017Date of Patent: September 3, 2019Assignee: ExxonMobil Research and Engineering CompanyInventors: Tien V.

Patent number: 10400184Abstract: Heavy oil feeds are hydroprocessed in the presence of a solvent and in the presence of a catalyst with a median pore size of about 85 ? to about 120 ? 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.Type: GrantFiled: August 29, 2012Date of Patent: September 3, 2019Assignee: ExxonMobil Research and Engineering CompanyInventors: Hyung Suk Woo, Jane Chi-Ya Cheng, Teh C.

Patent number: 10400185Abstract: Systems and methods are provided for block operation during lubricant and/or fuels production from deasphalted oil. During “block” operation, a deasphalted oil and/or the hydroprocessed effluent from an initial processing stage can be split into a plurality of fractions. The fractions can correspond, for example, to feed fractions suitable for forming a light neutral fraction, a heavy neutral fraction, and a bright stock fraction, or the plurality of fractions can correspond to any other convenient split into separate fractions. The plurality of separate fractions can then be processed separately in the process train (or in the sweet portion of the process train) for forming fuels and/or lubricant base stocks. This can allow for formation of unexpected base stock compositions.Type: GrantFiled: June 23, 2017Date of Patent: September 3, 2019Assignee: EXXONMOBIL RESEARCH AND ENGINEERING COMPANYInventors: Lisa I-Ching Yeh, Yogi V.

Patent number: 10363516Abstract: In various aspects, apparatuses and methods are provided for low pressure drop gas separations. In PSA processes, where there are large swings in pressure and corresponding swings in fluid velocity through the adsorbent, mechanical stresses during pressure cycling are of considerable concern. When that pressure is relieved in a lower pressure portion of the cycle, the high velocity of gas moving through the adsorbent bed can erode, strip away, or otherwise damage the channels within the adsorbent. Provided herein are methods which utilize flexible boundaries between adsorbent beds that are operated out of phase with one another. The flexible boundaries permit an increase in void space through the adsorbent during high pressure stages of the cycle and a decrease in void space through the adsorbent during low pressure stages of the cycle.Type: GrantFiled: July 19, 2017Date of Patent: July 30, 2019Assignee: ExxonMobil Research and Engineering CompanyInventor: Narasimhan Sundaram

Patent number: 10350538Abstract: In various aspects, methods are provided for hydrogen production while reducing and/or mitigating emissions during various refinery processes that produce syngas, such as power generation. Syngas can be effectively separated to generate high purity carbon dioxide and hydrogen streams, while reducing and/or minimizing the energy required for the separation, and without needing to reduce the temperature of the flue gas. In various aspects, the operating conditions, such as high temperature, mixed metal oxide adsorbents, and cycle variations, for a pressure swing adsorption reactor can be selected to minimize energy penalties while still effectively capturing the CO2 present in syngas.Type: GrantFiled: July 19, 2017Date of Patent: July 16, 2019Assignee: EXXONMOBIL RESEARCH AND ENGINEERING COMPANYInventors: Narasimhan Sundaram, Hans Thomann, David C.

Patent number: 10350537Abstract: Methods are provided for the production of nitrogen, hydrogen, and carbon dioxide from an exhaust gas. Exhaust gas from combustion in a fuel rich (or reducing) atmosphere is primarily composed of CO2, CO, N2, H2O, and H2. CO may be converted to CO2 and H2 via the water gas shift reaction. Carbon dioxide may then be effectively separated from nitrogen and hydrogen to produce a carbon dioxide stream and a nitrogen/hydrogen stream. The nitrogen/hydrogen stream may then be effectively separated to produce a high purity nitrogen stream and a high purity hydrogen stream. The process may be done in any order, such as separating the nitrogen first or the carbon dioxide first.Type: GrantFiled: July 19, 2017Date of Patent: July 16, 2019Assignee: EXXONMOBIL RESEARCH AND ENGINEERING COMPANYInventors: Narasimhan Sundaram, Hans Thomann
