摘要： A process for generating electricity from a fuel cell includes generating a hydrogen-rich gas as the fuel for the fuel cell by treating a hydrocarbon feed, which may be a normally liquid feed, in an autothermal reformer utilizing a first monolithic catalyst zone having palladium and platinum catalytic components therein and a second, platinum group metal steam reforming catalyst. Air is used as the oxidant in the hydrocarbon reforming zone and a low oxygen to carbon ratio is maintained to control the amount of dilution of the hydrogen-rich gas with nitrogen of the air without sustaining an insupportable amount of carbon deposition on the catalyst. Anode vent gas may be utilized as the fuel to preheat the inlet stream to the reformer. The fuel cell and the reformer are preferably operated at elevated pressures, up to about a pressure of 150 psia for the fuel cell.

摘要： A method and apparatus converts time-resolved sensor signals into transfer functions and/or cumulative transfer function signals which can be attained by computation means such as by using Fast Fourier Transforms. A signal, as a means to assess catalyst performance such as a signal based on sensing oxygen concentration or air to fuel ratio or hydrocarbon concentration in motor vehicle exhaust in accordance with the present invention is in the time domain and has multiple components at different frequencies. The use of Fast Fourier Transforms isolates the various spectral densities which arise from different frequency components of the complex time domain signal. Cross spectral density function and power spectral density function are used to determine the transfer function. The analysis has been found to be substantially independent of operating conditions. The transfer function and cumulative transfer function have been found to be a precise indication of the catalyst performance. The catalyst performance can be signaled to the vehicle operator for on board diagnostics (OBD) of the catalyst.

摘要： A method and apparatus for carrying out partial oxidation of hydrocarbon feeds to produce hydrogen rich gases suitable for steam reforming, utilizes a monolithic platinum and palladium containing catalyst. The process comprises introducing an oxygen containing oxidant gas (e.g., air), steam and a hydrocarbon feed into a catalytic partial oxidation apparatus comprising an adiabatic reaction vessel. The oxidation catalyst preferably comprises platinum, palladium and optionally rhodium distended upon a stabilized alumina washcoat. At least one half by weight of the hydrocarbon feed is catalytically oxidized in the monolith at a high throughput rate to produce an effluent suitable for further processing, such as steam reforming.

摘要： A system for the control of the air-fuel ratio in an internal combustion engine incorporates an electronic control unit, a sensor of exhaust emissions and a valve for metering fuel with air to control the air-fuel ratio. The electronic control unit provides for the comparison of successive measurements of the sensor output voltage under conditions wherein the fuel valve is being operated for ever increasing richness or leaness until such time as the differential measurement drops below a predetermined amount. An offset voltage is then subtracted from or added to this voltage to calculate an operating set point voltage. Thereby, the system's accuracy is maintained through the compensation for changed sensor characteristics with aging.
