    The cracking is carried out with hydrogen at a pressure of 80 atm and a alyst of finely divided platinum on silica or alumina. Because excess hydrogen is present no alkenes are formed and high proportions of branched alkanes cycloalkanes and aromatics are produced which are essential in the formulation of high grade 'green' petrol. The hydrogen also decreases the tendency for the
