WebFuel and air are mixed thoroughly before entering the catalyst, which promotes chemical reactions and therefore releases the heat of combustion. Catalytic combustion can take place at equivalence ratios that are well below the lean extinction limit encountered in conventional combustion systems. Webcatalysis, in chemistry, the modification of the rate of a chemical reaction, usually an acceleration, by addition of a substance not consumed during the reaction. The rates of chemical reactions—that is, the velocities at which they occur—depend upon a number of factors, including the chemical nature of the reacting species and the external conditions …

WebCatalysis ( / kəˈtæləsɪs /) is the process of increasing the rate of a chemical reaction by adding a substance known as a catalyst [1] [2] ( / ˈkætəlɪst / ).
