The skyrocketing price of palladium, fueled by increased market demand for this precious metal, has turned into a wave of thefts of a car catalytic converter. According to the latest statistics, over the past six months, palladium prices have increased by more than 50%. As a result, this metal, which is actively used by automakers in a catalytic converter, designed to reduce harmful engine emissions, for the first time since 2002 has become more expensive than gold. This fact provoked the theft of catalysts. Removing a catalytic converter from the car is not too difficult. It takes several minutes, and video instructions can be found on the Internet.Thieves operate in groups: at night they drive up to the chosen vehicle, saw off the catalytic converter with a piston saw, and then drive on. It is difficult to find robbers, as they hand over the stolen catalysts for scrap at pick-up points that do not require identification. Experts attribute the growth in demand for palladium to new

A catalytic converter is one of the main elements of the exhaust system, performing the function of reducing the emission of harmful substances and exhaust gases into the atmosphere. It is usually installed on both gasoline and diesel power plants in close proximity to the exhaust manifold or muffler. The catalyst is subject to mandatory disposal, which is a complicated process that requires special equipment. The purchase of a catalytic converter has been carried out almost everywhere. The cost of every used car catalytic converter depends on: Type of device (metal or ceramic); Countries of origin (Germany, France, USA, Japan or China, RF); Car model, engine size, year of manufacture, country of assembly or where it was exported; From size: cut from the body, whole or broken, shredded; On the purity, degree of contamination of the delivered mass: with asbestos, cotton wool or without; From exchange quotations of prices for metals Pt, Pd, Rh and from
Learning more about cars and spare parts, one may face names and terms, which can seem new or even unknown. A catalytic converter in a vehicle or a car catalyst is an important part of the whole exhaust system. Its role is to serve to reduce the emission of harmful combustion products into the atmosphere. Talking about chemistry, the term catalyst is described as a substance, which can accelerate or cause a chemical reaction without participation in such a complex reaction itself. It is guaranteed by such substances as copper, nickel, gold, palladium, rhodium, chromium. The principle of operation of a car catalyst is precisely based on the ability of substances to accelerate the reaction. Most often, it is located immediately after the front pipe, but sometimes it is installed directly on a front pipe. They do this for faster warming up since it works effectively only at temperatures above 300 ° C. If you check exhaust gases that come out of a crankcase of the engine of any car,
A platinum catalyst is used in many vehicles today. It is one of the main elements of the exhaust system and reduces harmful emissions. Catalyst's body is plated with precious metals, which, under certain conditions, can be extracted. However, it is difficult to predict in advance how much platinum is contained in a car catalyst. The fundamental design of catalysts has hardly changed since its inception, which cannot be said about manufacturing technologies. In recent years, thermal and aerodynamic performance has been particularly improved, resulting in improved neutralization and long-term stability. The main parts of every catalyst are housing and exhaust system made of stainless steel (expensive materials); special pads (protection and fixation for the ceramic block); support material or block (metal or ceramic); intermediate fixing layer for precious metals; catalytically active layer. The stainless steel body of a catalyst A stainless steel housing is required to provide g
