Abstract
The invention relates to a fluid catalytic cracking process for the preparation of good quality hydrocarbon fractions with a high octane number starting from heavy hydrocarbon fractions of a poorer quality characterized in that the heavy hydrocarbon fraction is put in contact, under cracking conditions, with a catalytic composition comprising a conventional FCC catalyst and a quantity of between 3-60% of a hydrothermally stable microporous material containing titanium.
