E-mail:lizhi@pxball.cnWhat are catalyst balls used for?
What is the use of catalyst balls? What are their advantages? What factors affect their service life? What role do they play? All these questions are answered here because we are a catalyst ceramic ball factory.
Specific uses
Catalytic cracking: It converts heavy crude oil into light fuels such as gasoline and diesel. Catalyst balls (such as molecular sieve catalyst balls) can enhance the cracking efficiency and the yield of light oil.
Hydrofining: It removes impurities such as sulfur, nitrogen and oxygen from oil products, as well as unsaturated hydrocarbons, and improves the quality of oil products. Commonly used hydrofining catalyst balls (such as alumina balls loaded with nickel and molybdenum).
Organic synthesis: Synthesizing basic chemical raw materials such as ammonia and methanol: Promoting gas reactions (such as N₂+H₂→NH₃) through catalyst balls (such as iron-based catalyst balls and copper-based catalyst balls).
Ester synthesis, oxidation reactions, etc. : For instance, in the synthesis of ethyl acetate, acidic catalyst balls can accelerate the esterification reaction.
Automobile exhaust treatment: The catalyst balls (loaded with precious metals such as platinum, palladium and rhodium) used in three-way catalytic converters can convert CO, NO youdaoplaceholder0 and hydrocarbons into CO₂, N₂ and H₂O.
Industrial waste gas denitrification/desulfurization: In selective catalytic reduction (SCR) technology, catalyst balls (such as vanadium-titanium series catalyst balls) can reduce NO <s:1> to harmless N₂.
Advantage
Compared with catalysts of other shapes (such as granules and honeycombs), the spherical structure of catalyst balls has the characteristics of good fluidity, uniform filling and low wear rate. It is especially suitable for dynamic reaction systems such as fluidized beds and moving beds, which can improve catalytic efficiency and service life.
Service life
The service life of catalyst balls varies greatly, usually ranging from several months to several years, and is specifically influenced by multiple factors: the type is an important basis. Precious metal and molecular sieve types, due to their stronger stability, have a lifespan of more than three years, while carbon-based and photocatalytic types have a shorter lifespan, often within one year. The working conditions of the application scenarios are of vital importance. High temperatures, high concentrations of pollutants or impurities (such as sulfur, lead, and dust) can accelerate poisoning, sintering or clogging, and shorten the service life. In addition, whether the pretreatment is in place (such as removing toxins), whether the working condition control is stable (such as avoiding over-temperature), and whether regeneration maintenance is carried out (such as high-temperature purging and acid leaching revival) will also significantly affect its actual service life.
Definition
A catalyst ball is a spherical catalyst carrier or supported catalyst with a wide range of applications. Its core function is to accelerate the reaction rate (or improve the reaction selectivity) by reducing the activation energy of chemical reactions, while maintaining its chemical properties and quality basically unchanged before and after the reaction.
What is a catalyst ball? What role does it play? Where is it used?
Catalyst balls are spherical particles with catalytic activity, usually made by loading active components (such as precious metals, metal oxides, etc.) on carriers (such as alumina, molecular sieves, activated carbon, etc.). Their core function is to accelerate the reaction rate by reducing the activation energy of chemical reactions while maintaining their chemical properties unchanged before and after the reaction. It is widely applied in multiple fields, such as industrial waste gas treatment (such as denitrification, VOCs degradation), automotive exhaust purification, chemical production (such as ammonia synthesis, petroleum refining), wastewater treatment (such as organic pollutant degradation), and the energy sector (such as fuel cells, hydrogen energy preparation), playing a crucial role in enhancing reaction efficiency, reducing energy consumption, and controlling pollutant emissions.
