I. INTRODUCTION Back in the eighteen hundreds, the ancestors of the Maxim family pioneered inventions in explosives, airplanes, the horseless carriage, and even machine guns. In 1895, Hiram Stevens Maxim designed and built an airplane before the successful flight of the Wright brothers. The founder of the Maxim Silencer Company, Hiram Percy Maxim, was intensely interested in radio and was the founder of the American Radio Relay League, From this interest evolved the development of silencers. One of the first silencers Maxim ever manufactured was the gun silencer made famous in movies and mystery thrillers. The company expanded and began to build silencers for other noise sources such as reciprocating engines, vacuum pumps, compressors, high velocity steam and air discharges, etc. MAXIM engineers invented and manufactured jet engine test cells. First to manufacture industrial heat recovery equipment in the USA, leaders in evaporators for desalination, distillate fuel systems, and now--catalytic silencers. MAXIM's new catalytic converter-silencer provides control of both engine exhaust noise and nitrogen oxide emissions from stationary, natural gas fueled reciprocating engines. This manual is provided to assist in the application, installation, operation and maintenance of these units. The manual will cover reduction of NOX (oxides of nitrogen, generally NO2 and NO), hydrocarbons (HC), and carbon monoxide (CO) by use of a catalytic silencer on a stationary reciprocating engine that is fueled by natural gas. What is a catalyst and a catalytic silencer? Basically a catalyst is a substance or combination of substances which, when added to a chemical reaction system will accelerate or retard the rate of reaction and, at the end of that reaction time, will have the exact same chemical and physical properties, including the mass, with which it started. MAXIM's catalytic silencer is a semi-residential grade silencer containing a catalyst bed. II. OPERATION AND DESCRIPTION The principle of operation of MAXIM's catalytic silencer is quite simple. Hot exhaust gases from the engine flow through a catalyst bed where the emissions of NOX9 HC, and CO are reduced. The catalyst consists of a porous inorganic substrate impregnated with three noble metals: platinum, palladium and rhodium. The proportion of these noble metals is such that the conversion of emissions is maximized. In addition to emissions control, the noise from the exhaust is also reduced to a semi- residential level.
