The redn. of NO by CO or C3H6 in the presence of O2, a reaction of great technol. importance, was studied on porous polycryst. Rh catalyst films using a single-chamber and a wireless bipolar cell configuration. In the latter case the Rh catalyst films were ...
In a first paper (part I), prechamber ignition in cogeneration natural gas engines has been shown to significantly intensify and accelerate the combustion process, offering a further potential to reduce the exhaust gas emissions while keeping efficiency at ...
The reduction of NO by CO on Pt has been extensively investigated in the past since it helps to eliminate NO of the exhaust gas of cars. However, the dissociation of NO in this reaction and the deactivation of the NO/CO reaction on Pt-supported catalysts s ...
The operation of the small size cogeneration gas engine (6 cylinders, 122mm bore, 142mm stroke) modified for unscavenged prechamber ignition was experimentally investigated. The objective was to evaluate the potential to reduce the exhaust gas emissions, p ...
The operation of a cogeneration internal combustion engine with unscavenged prechamber ignition was investigated. The objective was to evaluate the potential to reduce the exhaust gas emissions, particularly the CO emissions, without exhaust gas after trea ...
The object of this work is to test the unscavenged prechamber ignition system on a 150 kW cogeneration engine feed with biogas. The engine performances in term of fuel conversion efficiency are observed and the reduction potential f the exhaust emissions b ...
In order to determine the origin of the CO emissions from a cogeneration spark ignition engine fuelled with a lean natural gas-air mixture, the influence of several combustion chamber parameters have been measured in detail. In an attempt to interpret the ...
The kinetics and the mechanism of the selective redn. of nitric oxides (NOx) by hydrogen is studied on a trimetallic Pt-Mo-Co/a-Al2O3 catalyst under oxidizing conditions. This system is interesting in view of an exhaust gas control of power plants or lean- ...
The operation of a cogeneration internal combustion engine with unscavenged prechamber ignition was investigated. The objective was to evaluate the potential to reduce the exhaust gas emissions, particularly the CO emissions, below the Swiss limits (NOx an ...
The kinetics and the mechanism of the selective reduction of nitric oxides (NOx) by hydrogen is studied on a trimetallic Pt–Mo–Co/a-Al2O3 catalyst under oxidising conditions. This system is interesting in view of an exhaust gas control of power plants or l ...
