  • Publication number: 20190383185
    Abstract: An apparatus for reactivating a sulfur poisoned oxidation catalyst operating in the exhaust of a lean burn, methane source (as in natural gas) fueled combustion device as in an engine. The reactivation includes desulfation of the poisoned catalyst through the use of a CO supplementation apparatus in communication with the control unit that is adapted to supplement the CO content in the exhaust reaching the catalyst, while avoiding an overall rich exhaust atmosphere at the catalyst. An example includes the added supply of hydrocarbons to one or more, preferably less than all, of the lean burn engine's combustion chambers such as by an ECU controlled extra supply of NG (e.g., CNG) to some of the combustion chambers.

  • Patent number: 10184374
    Abstract: Apparatus for reactivating a sulfur poisoned oxidation catalyst operating in exhaust of a lean burn, methane source fueled combustion device. Reactivation includes desulfation of the poisoned catalyst through a CO supplementation apparatus communicating with the control unit that is adapted to supplement CO content in exhaust reaching the catalyst, while avoiding an overall rich exhaust atmosphere at the catalyst (e.g., an added supply of hydrocarbons to one or more-of the lean burn engine's combustion chambers as by an ECU controlled extra supply of NG to some of the combustion chambers). Also featured is a method for desulfation of an oxidation catalyst of a lean burn CNG engine by supplying excess CO to exhaust reaching the catalyst while retaining an overall lean state, and a method of assembling an apparatus for reactivating a sulfur deactivated lean burn NG engine catalyst by assembling a CO supplementation apparatus with control unit.

  • Publication number: 20110165681
    Abstract: In a method for adjusting the voltage potential or pH of, or cause proton release from, cells, subcellular regions, or extracellular regions, a gene encoding for a light-driven proton pump is incorporated into at least one target cell or region, the proton pump operating in response to a specific wavelength of light. Expression of the gene is caused by exposing the target cell or region to the specific wavelength of light in a manner designed to cause the voltage potential adjustment, pH adjustment, or proton release. The proton pump may be a microbial rhodopsin, in particular derived from the halorubrum genus of archaeabacteria, or be derived from leptosphaeria maculans, P. triticirepentis, and S. scelorotorium. The voltage potential of the target cell or region may adjusted until it is hyperpolarized in order to achieve neural silencing. Light-activated proton pumps responsive to different wavelengths of light may be used together to achieve multi-color neural silencing.
