Hydrocracking is a process to convert larger hydrocarbon molecules into smaller molecules under high hydrogen pressure and elevated temperature. It is commonly applied to upgrade the heavier fractions of the crude oils to produce higher value transportation fuels.

What is the purpose of hydrocracking?

Hydrocracking is usually performed on heavy gas oils and residues, to remove feed contaminants (nitrogen, sulfur, metals) and to convert them into lighter fractions including diesel gasoils.

What is hydrocracking catalyst?

Hydrocracking is a two-stage process combining catalytic cracking and hydrogenation, wherein heavier feedstocks are cracked in the presence of hydrogen. The reaction typically involves a reactor section, gas separator, scrubber for sulfur removal, and product fractionator.
