Abstract

Catalytic cracking of petroleum to obtain lower boiling hydrocarbon fractions is today the most important catalytic process. Reforming of the middle and heavy fractions of cracking products is a close second to this process. Hydrocracking is a special form of catalytic cracking, It is performed in the presence ofhydrogen and has proved to be very flexible to meet the fluctuating market demands for gasoline. By applying different operating conditions it is possible to convert 75 % of petroleum to gasoline or 60 % to middle distillates light fuel oil, diesel, jet fuel in the same reactor. Light gasoline, a major product of hydrocracking, has a high octane number due to its high isoparaffin content.
