Catalytic oxidizers in automobiles and industry reduce toxic emissions by oxidizing carbon monoxide and hydrocarbons, while reducing oxides of nitrogen. They use platinum and palladium/rhodium as catalysts and cannot operate in the presence of lead. While they have improved over the years, reducing CO2 emissions remains difficult. A catalytic oxidizer, or catalytic converter, is an […]
Catalytic converters in cars reduce harmful emissions, required in the US since 1975. They use metal catalysts to convert noxious gases into less harmful ones, but also contribute to global warming. A catalytic converter is a device installed in automobiles that is designed to reduce harmful emissions released from the vehicle’s exhaust. In the United […]
Catalytic reforming converts low-octane naphtha into high-octane reformates, used in various industries or as gasoline additives. The process rearranges hydrocarbon molecules to form complex structures with high octane values, producing desirable by-products such as benzene and isopentane. Various versions of the process use noble metal catalysts and high heat and pressure. Catalytic reforming is a […]
Catalytic activity is the acceleration of chemical reactions by a substance that is not modified in the process. In biological systems, enzymes regulate catalysis, reducing the energy required for reactions. Enzymes are essential for cellular functions and are regulated by feedback inhibition and environmental changes. Catalytic activity is the increase in the rate and energy […]
