Heavy oil is passed through metal chambers under high pressure and temperature in the presence of catalysts such as alumina, silica, or zeolites. This boiling breaks up heavy, large, more complex long-chain oil molecules into lighter, smaller, and simpler short-chain molecules.

What is in a catalytic converter?
A catalytic converter works by the various precious minerals and metals inside it. Quite simply they convert the dangerous chemicals inside the exhaust gases(carbon monixide,NOx etc) into less harmful ones (carbon dioxide etc). Due to the minerals and metals inside though they are often target to thieves as they can fetch quite a high price at the scrap yard. The catalytic converters that got stole off the HGV's at our work had a value of £800!Catalytic converters work by having the heated gases react with the precious metals in the catalytic converter. There is platinum palladium and rhodium in a catalytic converter all three are very expensive and rare metals. Because of the honeycomb shape of the catalytic biscuit there is a lot of surface area for the gas to be neutralized on.Prior to catalytic converters being on every car for every mile you drove your car would punch out somewhere around 100g's of pollution. After the addition of catalytic converters with platinum and palladium this number dropped to less than 1g of pollution per mile. After the addition of rhodium it dropped N/E which is non detectable.
What word is used to describe the sound of planes?
Air-crafts make a sonic boom known as a "boom'sound or 'whip cracking' (cracking) sound.
What is the lifespan of a catalytic converter?
That depends on the engine and the fuel you've used. If the engine starts burning oil a catalytic converter can fail rapidly. Some fuel additives can also cause a catalytic converter to fail prematurely.
Can you use acrylic paint on roman shades without it cracking?
If you are doing a stencil or decorative figures on the shades, it will work as long as you don't try to put the paint on too thick or try to made solid lines.
Can you put the catalytic converter before the muffler?
The catalytic converter is always in front of the muffler. Somewhere in the first third of the exaust system. Varies car to car.
What is difference between thermal and catalytic cracking?
Thermal CRacking is caused by heat while catalytic cracking is not caused by heat
What are the advantages of thermal cracking over catalytic cracking?
Carbonium ion process
What are the advantages of catalytic cracking over thermal cracking?
Carbonium ion process
Does cracking need a catalyst?
Cracking, the process of breaking down large hydrocarbon molecules into smaller ones, can occur via thermal or catalytic methods. While thermal cracking does not require a catalyst and relies on high temperatures, catalytic cracking utilizes a catalyst to lower the temperature and improve the efficiency of the reaction. The catalyst enhances the reaction rate and selectivity of the desired products, making catalytic cracking more economically advantageous in many refining processes.
What is an example of catalytic cracking?
"Cat cracking" is the process used to break crude oil down into gasoline, kerosene, adn fuel oils.
How do you make bio-kerosene?
bio kerosine is made from the catalytic cracking of bio diesel
How do you make bio kerosene?
bio kerosine is made from the catalytic cracking of bio diesel
What does FCC means in distillation?
Fluid catalytic cracking. It is a conversion process used in petroleum refineries.
What is cracking and what chemicals does it produce?
Catalytic cracking is the process of reacting a heated hydrocarbon with a catalyst such as iron or platinum to produce two or more lighter hydrocarbons with smaller carbon chains.
What is the term given to breaking of long hydrocarbon chains?
The term given to breaking of long hydrocarbon chains is "cracking." Cracking is a process that breaks down complex hydrocarbons into simpler molecules like light hydrocarbons such as ethylene, propylene, and butylene.
What conditions does cracking have to be carried out in?
Cracking must be conducted under specific conditions, typically high temperatures (around 450-750°C) and moderate to high pressures, depending on the type of cracking process used (thermal or catalytic). The presence of a catalyst can enhance the reaction rate and yield of desired products, particularly in catalytic cracking. Additionally, the feedstock composition and the desired end products also influence the conditions required for efficient cracking. Safety measures are crucial due to the flammable nature of the hydrocarbons involved.
What are the advantages of catalyst cracking over thermal cracking?
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.
