Patent number: 11905868Abstract: A system that may include an exhaust gas source that provides exhaust gas pollutants, a primary catalytic converter coupled downstream of the exhaust gas source, and an adsorption unit, configured to adsorb exhaust gas pollutants. The adsorption unit may be coupled downstream of the exhaust gas source. A process that may include introducing exhaust gas comprising exhaust gas pollutants into a system that includes an adsorption unit, such that the exhaust gas may flow through the adsorption unit and the exhaust gas pollutants may be adsorbed into an adsorption media in the adsorption unit as adsorbed exhaust gas pollutants. A depleted exhaust gas may pass from the adsorption unit.Type: GrantFiled: December 17, 2021Date of Patent: February 20, 2024Assignee: SAUDI ARABIAN OIL COMPANYInventors: Emmanuel Laigle, Christophe Chaillou, Caroline Norsic, André Nicolle

Patent number: 11767781Abstract: An exhaust treatment system includes an exhaust line, a series of emission treatment units, and an electronic control unit. The series of emission treatment units includes a catalytic unit, a particulate filter unit, an oxidation catalytic unit, a hydrogen injection unit, and a Lean NOx Trap (LNT) for trapping select emissions. A method of operating an exhaust treatment system includes introducing a fuel to a combustion engine of a motor vehicle, directing emissions from the combustion engine to an exhaust line, and passing the emissions in the exhaust line through a series of emission treatment units on the exhaust line. The method further includes injecting hydrogen into the exhaust line via a hydrogen injection unit, where an amount of hydrogen gas injected from a hydrogen inlet line reduces the trapped emissions in the LNT to an inert gas.Type: GrantFiled: February 18, 2022Date of Patent: September 26, 2023Assignee: SAUDI ARABIAN OIL COMPANYInventors: Emmanuel Laigle, Christophe Chaillou, Caroline Norsic, André Nicolle

Patent number: 11686236Abstract: An exhaust gas purifying system for an engine includes a three-way catalyst, a particulate filter, an ammonia sorbent unit, an exhaust gas purifying catalyst unit, and a gas injection component including an oxygen-containing gas, all coupled to an exhaust line. Methods for purifying exhaust gas from an engine include exposing the exhaust gas to a three-way catalyst and a particulate filter, thus generating ammonia. The ammonia may be stored in an ammonia sorbent unit during a cold start condition. An oxygen-containing gas may be injected into the exhaust line. Once the ammonia sorbent has reached a desorption temperature, the ammonia may be released into the exhaust line and exposed to an exhaust gas purifying catalyst unit. The exhaust gas purifying catalyst partially oxidizes the ammonia to nitrous oxides (NOx) and subsequently catalyzes a reaction between the remaining ammonia and the nitrous oxides to give nitrogen gas and water.Type: GrantFiled: February 18, 2022Date of Patent: June 27, 2023Assignee: SAUDI ARABIAN OIL COMPANYInventors: Emmanuel Laigle, Christophe Chaillou, Caroline Norsic, André Nicolle

Patent number: 11661872Abstract: An exhaust purification system may include at least one catalyst in an exhaust flow path of an internal combustion engine to decrease gaseous pollutants from an exhaust gas, a first particulate filter downstream of the catalyst, and a second particulate filter with a porosity lower and a lower mean pore size than the first particulate filter and in a bypass flow line downstream of the first particulate filter, the bypass flow line being configured to open and close based on at least one condition of the exhaust purification system or conditions of the exhaust gas. The second particulate filter may be configured to be removed and replaced when full. A method of purifying an exhaust gas through the exhaust purification system is also described.Type: GrantFiled: January 8, 2021Date of Patent: May 30, 2023Assignee: SAUDI ARABIAN OIL COMPANYInventors: Emmanuel Laigle, Christophe Chaillou, Caroline Norsic, André Nicolle

Patent number: 11441464Abstract: Systems for reducing the content of residual pollutants from tailpipes emissions in an exhaust line having a cold part may include an ozone generation system; an MnO2 catalyst; and a lean NOx trap (LNT) catalyst. In these systems, the ozone, MnO2 catalyst, and LNT catalyst may be provided in the cold part of the exhaust line. In these systems, the residuals pollutants may be oxidized at temperatures of from about 20° C. to about 150° C. in rich or lean conditions and NO2 may have a concentration of less than 0.1 mg/km in the tailpipe emissions downstream of the cold part of the exhaust line. Corresponding methods may include generating ozone from an ozonizer; injecting the ozone in a mixing chamber comprising the residual pollutants to form a first mixture; converting the first mixture using an MnO2 catalyst to form a second mixture; and converting the second mixture using an LNT catalyst.Type: GrantFiled: February 2, 2021Date of Patent: September 13, 2022Assignee: SAUDI ARABIAN OIL COMPANYInventors: Emmanuel Laigle, Christophe Chaillou, Caroline Norsic, André Nicolle

Patent number: 8098230Abstract: A ground-based haptic interface equipped with at least two decoupled rotary finger actuators adapted to be manipulated with the fingertips of a single hand of a user. For each finger actuator, a means are included for measuring the angular position of the actuator or for measuring the torque applied on the axis of rotation of the actuator. Each rotary finger actuator is associated with a control motor adapted to apply, on the axis of rotation of the actuator, a torque that is a function of the angular position of the actuator, or that controls the rotational position of the axis of rotation of the actuator as a function of the torque applied on this axis. The haptic interface can be used as a peripheral of a computer, for example, for interacting with a virtual environment. It can also be applied to the control or manipulation of real objects by being coupled, for example, with a robot or a manipulating arm. The interface also can be telemanipulated.Type: GrantFiled: May 27, 2008Date of Patent: January 17, 2012Assignees: Universite des Sciences et Technologies de Lille Cites Scientifique, Centre National de Recherche ScientifiqueInventors: Gery Casiez, Christophe Chaillou, Betty Semail, Patricia Plenacoste
