There are two good economic reasons for cracking oil fractions – (i) there isn't enough of fuels like petrol or diesel in the original crude oil and (ii) alkenes are NOT found in oil, so must be manufactured from oil. petrol or diesel) and alkenes which are used to make polymers–plastics and other important compounds. The products are smaller alkanes used for fuels (e.g. – Cracking is a thermal decomposition process by which large alkane hydrocarbon molecules are broken down by passing them over a heated catalyst at high pressure. Cracking – a problem of supply and demand, other products Oil, useful products, environmental problems, introduction to organic chemistryĦ.
