Description

Distillation can only extract materials which are naturally present in the crude oil to start with. Because the share of petrol in the crude oil is insufficient to cover the need, however, conversion processes (modification processes) have been developed. They include, along with thermal cracking, also the catalytic cracking which is carried out in experiment C2.3.2.3. Here, paraffin oil is cracked in the heat of a bead catalyst and the gaseous and liquid fractions are collected.
