GCSE Edexcel Chemistry Cracking & Alkenes: During fractional distillation,

Question

During fractional distillation, crude oil is separated into a number of fractions.

The table shows the relative amount of these fractions that can be obtained from crude oil.

The table also shows the relative demand for each of these fractions.

| fraction                    | relative amount obtained | relative demand |
|----------------------------|-------------------------|-----------------|
| LPG                        | 2                       | 6               |
| petrol                     | 12                      | 29              |
| kerosene                   | 16                      | 11              |
| diesel                     | 24                      | 29              |
| fuel oil and bitumen       | 46                      | 25              |
