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.

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.
How you do you use these catalyst in tire pyrolysis?
In tire pyrolysis, catalysts are used to enhance the breakdown of complex organic materials in tires into simpler hydrocarbons, improving the yield of valuable products like oils and gases. Common catalysts, such as zeolites or metal oxides, facilitate the cracking process and reduce the activation energy required for decomposition. By optimizing reaction conditions, catalysts can also help in reducing unwanted by-products and improving the overall efficiency of the pyrolysis process. Ultimately, their use leads to higher quality end products and a more sustainable approach to tire waste management.
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.
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.

Why is porous pot catalyst used in cracking hydrocarbons?
The 'porous pot' that is used in a lab, is used to facilitate the cracking process during heating, the porous pot is used as a catalyst to speed up the cracking process. This allows for the process to occur at a lower temperature.
Fixed bed catalytic cracking?
A cyclic, regenerable process for cracking of petroleum distillates to produce high-octane gasoline from higher-boiling petroleum fractions; synthetic or natural bead catalysts of activated hydrosilicate of alumina may be used. Also known as Houdry process.
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.
