Getting Enough Petrol
Relative supply and demand for fuel oil and gasoline fractions of North Sea Oil
There is a mismatch between supply and demand for the different fractions of crude oil.
Cracking helps to solve the problem by breaking down large molecules in the fuel oil fraction to smaller alkanes useful in petrol. Cracking was first done by heat alone, and then since the 1940's over a silica/alumina catalyst in a fluidised bed reactor, called a cat cracker.
Meeting the demand for petrol is a massive undertaking, requiring the output from hugh catalytic cracking plants.
