![]() ![]() ![]() ![]() Alternative balanced equation for the cracking of decane cracked#įor example, decane (an alkane with 10 carbons) can be cracked to produce octane and ethene. C10H22 (g) - C8H18 (g) + C2H4 (g) Organic compounds Crude oil is a mixture of hydrocarbons and is separated into. Lets look at the structures of the first three members of the alkenes, shown in Fig.2 below.ĪtomAn atom is the smallest particle of an element that can still be defined as that element. So while the alkanes are saturated hydrocarbons, the alkenes are unsaturated hydrocarbons. Have you heard of the unsaturated oils we use to make margarine These contain double bonds in their carbon chains too. Some of them are called polyunsaturates because their molecules have more than one double bond. They are a healthier option than the saturated fats we eat in butter.

They are less likely to clog up your arteries with the fatty deposits that can cause heart disease. Summary Oil companies break large hydrocabon molecules down into smaller, more useful hydrocarbons.Ĭracking takes place at high temperatures as the large molecules pass over a catalyst. One of the by-products of this thermal decomposition reaction is ethene.Shorter chained hydrocarbons are more useful than longer chained ones because longer chained hydrocarbons are very viscous (do not flow well – like golden syrup) and are harder to ignite (set fire to). Cracking is a process that breaks down less useful longer chained hydrocarbons, like bitumen, into shorter more useful hydrocarbons, which are less viscous and easier to ignite. ![]() Some of the smaller hydrocarbons are used as fuels and others are used to make polymers.Ĭracking is a thermal decomposition reaction, which is the breaking down of molecules using heat (thermal decomposition is an endothermic reaction as energy/ heat is taken in). Thermal decomposition occurs as the longer chained hydrocarbon splits up into smaller chained hydrocarbons.Pass the vaporised long-chained hydrocarbon over a powdered catalyst sometimes aluminium oxide (a catalyst is something that increases the rate of reaction without being used up in the reaction).Heat up the long-chained hydrocarbon so that they turn into a gas (vaporise).There are 2 different types of cracking catalytic cracking and steam cracking. One of the hydrocarbons produced will be an alkane and the other will be an alkene. The process for steam cracking is essentially the same.
