| 20130040802 | DESULFURIZATION METHOD FOR LNT SYSTEM - A desulfurization method of a nitrogen oxide absorption catalyst when diesel is used may include determining how many times a regeneration of a diesel particulate filter (DPF) is completed, ending a DPF regeneration, if the number of times of the DPF regeneration reaches a predetermined value and entering into a desulfurization mode to desulfurize the DPF, ending the desulfurization mode after the desulfurization mode is performed for a predetermined time, and calculating a particulate matters (PM) amount that is trapped in the DPF after the desulfurization, compensating the trapped PM amount, and determining a time of the DPF regeneration. A desulfurization timing is determined based on the number of times that the DPF is regenerated to be able to simplify the desulfurization logic and also reduce the memory of ECU, when the LNT catalyst is poisoned by a small amount of sulfur included in exhaust gas. | 02-14-2013 |
| 20130225393 | PROCESS FOR THE REGENERATION OF A CATALYST - Process for the regeneration of an at least partially coked molecular sieve catalyst comprising introducing the at least partially coked catalyst into a regenerator; introducing into the regenerator an oxygen-containing gas to regenerate at least part of the at least partially coked catalyst, thereby producing a gaseous mixture and at least partially regenerated catalyst; separating at least partially regenerated catalyst and at least part of the gaseous mixture; and analysing the composition of the gaseous mixture to control the burning rate of the coke present on the at least partially coked catalyst in the regenerator by adjusting the mass flow rate of the oxygen-containing gas on the basis of the analysis of the gaseous mixture. | 08-29-2013 |
| 20130225394 | PROCESS FOR THE REGENERATION OF A CATALYST - Process for the regeneration of an at least partially coked molecular sieve catalyst comprising introducing the at least partially coked catalyst into a regenerator; introducing into the regenerator an oxygen-containing gas to regenerate at least part of the at least partially coked catalyst, thereby producing a gaseous mixture and at least partially regenerated catalyst; recovering part of the at least partially regenerated catalyst; analysing the at least partially regenerated catalyst to control the burning rate of the coke present on the at least partially coked catalyst in the regenerator by adjusting one or more conditions of the regeneration of the at least partially coked catalyst on the basis of the analysis of the at least partially regenerated catalyst; and separating at least partially regenerated catalyst and at least part of the gaseous mixture as obtained in step (b). | 08-29-2013 |
