History The catalytic convertor was invented by Eugene Houdry, a French mechanically skillful engineer and expert in catalytic oil refining[2] who lived in the U.S. around 1950. When the results of early studies of smog in Los Angeles were published, Houdry became concerned to the highest degree the role of automobile exhaust in air taint and founded a special company, Oxy-Catalyst, to develop catalytic convertors for gasoline engines an caprice ahead of its time for which he was awarded a patent (US2742437). widespread adoption had to wait until the extremely sound anti-knock agent tetraethyl head for the hills was eliminated from most gasoline everyplace environmental concerns, for the lead would muck the converter by forming a lotion on the particle accelerators surface, efficaciously disabling it.[3] The catalytic converter was tho developed by John J. Mooney and Carl D. Keith at the Engelhard Corporation,[4] creating the first yield catalytic converter in 1973.[5 ] [edit] Construction Metal-core converter Ceramic-core converter The catalytic converter consists of several components: 1. The catalyst core, or substrate.

For self-propelled catalytic converters, the core is often a ceramic monolith with a honeycomb structure, but metallic foil monoliths do of FeCrAl were introduced in the 1990s and are used by some automotive manufacturers.[citation needed] The honeycomb geometry provides a high surface area to tolerate the catalyst washcoat, and therefore is often called a catalyst tide everywhere.[citation needed] The cordierite ceramic substrate used in most catalytic converters was invented by Rodney! Bagley, Irwin Lachman and Ronald Lewis at Corning Glass, for which they were inducted into the National Inventors Hall of Fame in 2002.[citation needed] 2. The washcoat. A washcoat is a carrier for the catalytic materials and is used to disperse the materials over a high surface area. Aluminum oxide, Titanium dioxide, te dioxide, or a mixture of silica and alumina screen end be used.
