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.

Why do you think cracking is called a thermal decomposition reaction?
heat is used to decompose long chain hydrocarbons into shorter chain hydrocarbons.
What type of reaction is cracking?
Cracking is the name given to breaking up large hydrocarbon molecules into smaller and more useful bits. This is achieved by using high pressures and temperatures without a catalyst, or lower temperatures and pressures in the presence of a catalyst. The source of the large hydrocarbon molecules is often the naphtha fraction or the gas oil fraction from the fractional distillation of crude oil (petroleum). These fractions are obtained from the distillation process as liquids, but are re-vaporised before cracking. There isn't any single unique reaction happening in the cracker. The hydrocarbon molecules are broken up in a fairly random way to produce mixtures of smaller hydrocarbons, some of which have carbon-carbon double bonds. One possible reaction involving the hydrocarbon C15H32 might be:
Why would an oil company want to crack hydrocarbons?
Cracking of crude oil is needed because it gives the item more uses. Also, it provides a larger supply of the item, it is essential to crack crude oil because otherwise we would have run out years ago.
Which Catalyst used in manufacture of sulfuric acid?
the widely used catalyst is V2O5 .
Why hydrocarbons are used as fuel?
There are two reasons : 1) Higher calorific value 2) Large chain hydrocarbons have high impurities and when broken into smaller chain compounds their volumetric rate increases. So for the same mass we get a higher volume and this translates into greater profitability.

Can pt and pd be used in the hydrogenation of alkenes?
Pt and Pd can be used as catalyst in the hydrogenation of alkenes or (de)hydrogenation of hydrocarbons (cracking in petrol industry)
What is a broken pot catalyst?
A Catalyst used to "Break Down" Long Hydrocarbons into smaller, more useful ones...
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.

Why dilution steam is used in steam cracking of hydrocarbons?
Dilution steam is added to reduce the partial pressure of hydrocarbons. This is done to aid the reaction to proceed in the forward direction to get desired products as per Le Chatlier's principle.

How are cracking reactions used to increase the amount of petrol that is harvested?
Cracking reactions in a refinery crack high molecular weight, long chain molecules into lower molecular weight hydrocarbons that can be blended into the motor fuels pool. This is typically done in a refinery process unit known as a coker or visbreaker. The products usually require further processing, such as hydrodesulfurization, before they can be blended into motor fuels. Without these cracking reactions, the long chain hydrocarbons would be used as heavy fuel oil. Heavy fuel oil is used for fuel by large tanker ships or stationary boilers for residental or commerical buildings for heating during the winter.
Why are alkenes from alcohols not used on an industrial scale?
Since alcohols are obtained by hydration of alkenes, it is meaningless to manufacture alkenes from alkanes. Moreover, cracking hydrocarbons is a more effective and economical to make alkenes. Shawkat
