Catalytic cracking offers several advantages over thermal cracking, primarily in terms of efficiency and product quality. It operates at lower temperatures, which reduces energy consumption and minimizes the formation of unwanted by-products like coke. Additionally, catalytic cracking yields a higher proportion of valuable light products, such as gasoline and olefins, while thermal cracking often results in heavier, less desirable fractions. The presence of catalysts also allows for more selective reactions, enhancing overall process control and product specificity.

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.
What is a cracking of a oil fraction?
It is when you break large hydrocarbons/alkanes, into smaller more useful alkanes/alkenes. For example a large hydrocarbon in crude oil is Bitumen. By passing this substance over a hot catalyst, you can break it down into smaller hydrocarbons such as Petrol or Diesel
What is achieved in the process of cracking?
For anyone who has seen the previous answer ignore the immature remark. "Fuels made from oil mixtures containing large hydrocarbon molecules are not efficient. They do not flow easily and are difficult to ignite. Crude oil often contains too many large hydrocarbon molecules and not enough small hydrocarbon molecules to meet demand - this is where cracking comes in. Cracking allows large hydrocarbon molecules to be broken down into smaller, more useful hydrocarbon molecules. Fractions containing large hydrocarbon molecules are vaporized and passed over a hot catalyst. This breaks chemical bonds in the molecules, and forms smaller hydrocarbon molecules. Cracking is an example of a thermal decomposition reaction." Sources:http://www.bbc.co.uk.education2020.us/
What effect does a catalyst have?
A catalyst speeds up a chemical reaction by lowering the activation energy required for the reaction to occur. It does so by providing an alternative reaction pathway that requires less energy to initiate the reaction. The catalyst itself remains unchanged at the end of the reaction and can be used over and over again.
What causes thermal conductivity?
when heat travells through a material which over heats it. Thermal conduction then applies

What are the effects of thermal movement on buildings?
Thermal movement can cause expansion and contraction in building materials, leading to cracking, warping, or distortion. This can compromise the structural integrity of the building over time. Proper design and construction techniques that account for thermal movement can help minimize these effects.
What are the advantages and disadvantages of thermal expansion?
Advantages of thermal expansion include its use in designing and constructing structures that can accommodate temperature changes without damage. However, a disadvantage is that it can cause stress on materials, leading to potential structural issues over time. Managing thermal expansion is crucial to minimize negative effects.
What is the black solid that is formed in the combustion of hexane?
Coke, most likely. Coke is the carbonaceous residue left over from the thermal "cracking" of hydrocarbons (the term is also used to describe the residue left over from coal combustion).
What are the products of cracking decane?
The products of cracking decane typically include smaller alkanes such as ethene, propene, and butene, as well as hydrogen gas. Cracking decane involves breaking the carbon-carbon bonds in the decane molecule to form these smaller hydrocarbons.

How do you use catalyst in a sentence for murder?
The girl's constant cajoling was a catalyst in the circumstance of the callous murder.
What type of weathering is thermal heat expansion and contraction?
Thermal heat expansion and contraction is a type of mechanical weathering, as it involves the physical breakdown of rocks due to changes in temperature. When rocks heat up, they expand, and when they cool down, they contract, causing stress that can lead to cracking and disintegration over time.

What are asphalt's advantages over concrete?
Its physical properties also make it less susceptible to cracking and weathering; it is also more resistant to salts and chemicals used to clear and maintain roads in inclement weather.
