Morphology
catalytic + cracker
The phrase is compositionally built from 'catalytic' (relating to a catalyst) + 'cracker' (one that cracks), so a learner who knows both words can infer it denotes a device that performs cracking using a catalyst. However, the specific technical meaning—breaking large hydrocarbon molecules into lighter fuels in a refinery—is domain-specific and not fully predictable from general vocabulary knowledge, and 'cracker' can be ambiguous outside the industrial context.
Etymology
Catalytic cracker comes from the image of a machine whose name shows its parts: cracker means something that 'cracks' or breaks large oil molecules, and catalytic means it uses a 'catalyst' to help the change. So the name helps you remember it is a device that turns heavy oils into lighter 'fuels' by breaking molecules with a 'catalyst'.
