Primary sources
Carbon monoxide is produced in many industrial processes, such as ammonia feedstock, yellow phosphorus production tail gas, and blast furnace and converter gas in the steel industry. In terms of carbon monoxide resources, steel mill gas is huge. When the purity of carbon monoxide is required and the demand is not particularly large, carbon monoxide production equipment is often established, or by-product gas with lower treatment costs is used. Commonly used methods include coke oxygen method, carbon dioxide and charcoal reduction method, carbon dioxide into the charcoal layer of the electric furnace is reduced to carbon monoxide, synthetic ammonia copper washing and regeneration gas method.
Main applications
In the chemical industry, carbon monoxide is the basis of one-carbon chemistry. As the main component of syngas and various types of gas, carbon monoxide is an important raw material for the synthesis of a series of basic organic chemical products and intermediates, starting from carbon monoxide, almost all basic chemicals can be prepared, such as ammonia, phosgene and alcohols, acids, anhydrides, esters, aldehydes, ethers, amines, alkanes and olefins. At the same time, by using the properties of carbon monoxide and transition metals to form carbonyl metals or carbonyl metal derivatives, various homogeneous reaction catalysts required for organic chemical production can be prepared. In addition, carbon monoxide can be used as a terminator in polyethylene polymerization reactions.
In the metallurgical industry, carbon monoxide can be used to extract high-purity nickel from raw ores by using the thermal decomposition reaction of carbonyl metals, and can also be used to obtain high-purity powder metals (such as zinc white pigments) and produce certain high-purity metal films (such as tungsten film and molybdenum film). At the same time, carbon monoxide can be used as a reducing agent for refined metals, such as oxides used to reduce iron in steelmaking blast furnaces (see "Physical and Chemical Properties Chemical Properties" for the equation); In the production of polymorphic diamond films, research-grade carbon monoxide (≥ 99.99%) can be used to provide a carbon source for the chemical vapor deposition process. In addition, a mixture of carbon monoxide and hydrogen (syngas) can be used to produce certain special steels, such as direct reduced iron ore to produce sponge iron.
In addition to the chemical industry and metallurgical industry applications, carbon monoxide can also be used as fuel, high-purity carbon monoxide is mainly used as standard gas, carbon monoxide lasers, environmental monitoring and scientific research. Among them, carbon monoxide standard gas can be used in the calibration and detection of petrochemical process control instruments, petrochemical product quality control, environmental pollutant detection, automobile exhaust emission detection, mine alarm calibration, various factory exhaust gas detection, medical instrument calibration, power system transformer oil quality testing, air separation product quality control, traffic safety testing instrument calibration, geological exploration and seismic monitoring, metallurgical analysis, gas appliance experiment and calorific value analysis, fertilizer industry instrument calibration, etc.
In addition, carbon monoxide is often used in the preservation of fish, meat, fruits and vegetables and bagged rice, especially the preservation of sashimi, and is used as a color fixative because it can make the meat color rosy.
