Definition of heavy oil catalytic cracking

Heavy oil catalytic cracking is a refining process that converts heavy crude oil feedstocks into lighter petroleum products through the action of a catalyst. It is typically used to process high-viscosity heavy petroleum feedstocks, such as residue and sludge. There are no clear defining criteria for heavy oil catalytic cracking. Generally speaking, if the feedstock contains a high proportion of heavy components such as residue or sludge, a heavy oil catalytic cracking process can be considered. Furthermore, it is also necessary to determine whether to adopt this process based on the specific requirements of the refinery and the products. In practice, refineries take into account factors such as the composition of the feedstock, temperature, pressure, and catalyst selection in order to operate the heavy oil catalytic cracking process in the most optimal manner. This means that not all cases of blending residue oil are suitable for the heavy oil catalytic cracking process; a decision must be made based on the actual circumstances. .
