  • Publication number: 20250043195
    Abstract: In various aspects, systems and methods are provided for operating an oxygen-fired catalyst regenerator with flue gas recycle and CO2 capture. An oxygen-fired catalyst regenerator contrasts with an air-fired regenerator. The oxygen-fired catalyst regenerator substantially reduces nitrogen within the system, which facilitates CO2 capture by reducing the energy required to capture CO2. In various aspects, a first portion of the regenerator flue gas is passed to a CO2 capture system and a second portion is recycled to the regenerator. Before the flue gas is recycled or diverted to the CO2 capture, it is passed to various processes that remove and/or reduce SOx, NOx, particulate, and water content. In various aspects, a portion of the treated flue gas may be combined with substantially pure O2 and recycled to the regenerator.

  • Publication number: 20190264116
    Abstract: Adsorbents for aromatic adsorption are used to improve one or more properties of base stocks derived from deasphalted oil fractions. The adsorbents can allow for removal of polynuclear aromatics from an intermediate effluent or final effluent during base stock production. Removal of polynuclear aromatics can be beneficial for improving the color of heavy neutral base stocks and/or reducing the turbidity of bright stocks.

  • Publication number: 20170369392
    Abstract: In a process for the catalytic alkylation of an olefin with an isoparaffin, an olefin-containing feed is contacted with an isoparaffin-containing feed under alkylation conditions in the presence of a solid acid catalyst comprising a crystalline microporous material of the MWW framework types, wherein the olefin-containing feed consists essentially of pentenes.
