What is cracking product of decane?
What is cracking product of decane?
Sometimes, hydrogen is also produced during cracking. 1. Decane on cracking gives butane and an alkene with it.
What is catalytic cracking in chemistry?
Steam or catalytic degradation (cracking) refers to the degradation of a plastic by means of steam or a catalyst. In catalytic cracking solid catalysts effectively convert plastics into liquid fuel, giving lighter fractions as compared to thermal cracking.
What are the conditions for catalytic cracking?
Catalytic cracking uses a temperature of approximately 550°C and a catalyst known as a zeolite which contains aluminium oxide and silicon oxide. Steam cracking uses a higher temperature of over 800°C and no catalyst.
What is catalytic cracking of alkanes?
Catalytic Cracking Modern cracking uses zeolites as the catalyst. These are complex aluminosilicates, and are large lattices of aluminium, silicon and oxygen atoms carrying a negative charge. They are, of course, associated with positive ions such as sodium ions.
How can decane be separated from a mixture of alkanes?
Fractional distillation
- heated crude oil enters a tall fractionating column , which is hot at the bottom and gets cooler towards the top.
- vapours from the oil rise through the column.
- vapours condense when they become cool enough.
- liquids are led out of the column at different heights.
What are the products of cracking?
The products of cracking include alkanes and alkenes , members of a different homologous series . An alkene is a hydrocarbon that contains a carbon-carbon double bond.
What type of reaction is catalytic cracking?
The cracking reactions are endothermic, and the heat necessary to heat the hydrocarbon to the reaction temperature and to supply the heat of reaction is provided by the heat of combustion from burning the coke from the catalyst.

What are the two products of cracking?
the products of cracking include alkanes and alkenes , members of a different homologous series.
Which type of catalyst is used in catalytic cracking Mcq?
Which type of catalyst is used in catalytic cracking? Explanation: Earlier acid clays were used as a catalyst for catalytic cracking. Now silica and alumina with minor amounts of oxides of Ca, Mg, Na and rare earth are used as a catalyst.
What is cracking in chemistry examples?
Cracking is the mechanism of petrochemistry, petroleum geology, and organic chemistry whereby complicated organic molecules such as kerogens or long-chain hydrocarbons are broken down into simpler molecules such as light hydrocarbons by breaking carbon bonds in the precursors.
What is the difference between thermal cracking and catalytic cracking?
Thermal Cracking: Thermal cracking is the process of breaking down large compounds into small compounds at high temperatures and high pressures. Catalytic Cracking: Catalytic cracking is the breakdown of large compounds into small hydrocarbons using an acid catalyst.
