Generally platinium or palladium though other metals may be used. These are quite expensive metals. It's important these do not get "poisoned", ffor example in catalytic converters if lead fuel is used the lead will bond irreversibly to the metal and stop all sites where chemical reactions may happen on the surface. Whereas normally chemicals will chemisorb, react and the products will desorb due to volatility or the elevated temperature of operation.
Catalysts are used during the cracking process to speed up the reaction rate and lower the activation energy required for the reaction to occur. This helps to break down larger hydrocarbon molecules into smaller, more valuable products such as gasoline and diesel. Additionally, catalysts can help control the selectivity of the products formed during the cracking process.

Why is aluminium or broken porcelain used in cracking?
They have the role of a support for catalysts; I suppose that you think to aluminium oxide.
What is the name given to the process of breaking up the molecules of hydrocarbons?
The process is called 'cracking' or more properly "Fluid Catalytic Cracking". It takes place in a Catalytic Cracker (cat cracker) where a combination of high heat, pressure, and chemical catalysts break long chain hydrocarbons into more valuable shorter chain ones. A catalyst is a compound that speeds up (or slows down) a reaction without being used in the reaction. So a catalyst can be used over and over again for the same process.
Name four Industrial catalysts and their uses?
Iron catalysts are used in the Haber process for ammonia synthesis. Platinum catalysts are used in catalytic converters to convert harmful gases into less harmful ones. Vanadium pentoxide is a catalyst used in the production of sulfuric acid. Nickel catalysts are used in the hydrogenation of vegetable oils to produce margarine.
What are some salts used as catalysts?
Zeolites (aluminosilicates salts) are frequently used as catalysts.
Can catalyst initiate reaction?
Yes, catalysts can initiate or speed up a reaction by lowering the activation energy required for the reaction to occur. They do not undergo any permanent changes during the reaction process and can be used repeatedly.
Why must air not enter the reactor during cracking?
Air should not enter the reactor during cracking to prevent oxidation of the products. Oxidation can lead to undesired reactions and decrease the efficiency of the cracking process. Additionally, oxygen in the air can cause damage to the catalysts used in the reactor.

What is the process that is used to refine petroleum called?
Cracking
What is the process that is used to refined petroleum called?
Cracking
Fixed bed catalytic cracking?
Fixed bed catalytic cracking is a refining process that uses a catalyst to break down heavy hydrocarbons into lighter products such as gasoline and diesel. The process occurs in a fixed catalyst bed within a reactor, with the catalyst facilitating the cracking of larger molecules into smaller ones. This method is commonly used in petroleum refineries to increase the yield of valuable products from crude oil.
Why is porous pot catalyst used in cracking hydrocarbons?
A porous pot catalyst is used in cracking hydrocarbons to provide a large surface area for the reaction to occur, increasing the efficiency of the process. The catalyst helps lower the activation energy required for the cracking reaction, allowing it to proceed at lower temperatures and reducing energy consumption. Additionally, the porous structure of the catalyst allows for better contact between the reactants and the catalyst, enhancing the rate of the reaction.
What is an example of catalytic cracking?
"Cat cracking" is the process used to break crude oil down into gasoline, kerosene, adn fuel oils.

What can you do to prevent your Chrysler dashboard from cracking?
There is no certain way to prevent your Chrysler dashboard from cracking. The cracking is typically a result of a defective plastic being used to make the dashboard, a faulty manufacturing process, or an engineering flaw.

What does FCC means in distillation?
Fluid catalytic cracking. It is a conversion process used in petroleum refineries.
How are catalysts used?
