Morphology

cat + cracker

The phrase names a specialized industrial device (short for 'catalytic cracker') whose meaning is not derivable from the listed constituent senses: 'cat' (a tracked machine) and an undefined 'cracker'. Understanding requires technical knowledge or recognition of the abbreviation 'cat' = 'catalytic' and the industrial sense of 'cracking', so a B1 learner who only knows the literal constituents would not infer the MWE meaning.

Etymology

Cat cracker comes from the short form cat of 'catalytic' plus cracker, because the unit 'cracks' heavy oil into smaller parts. It uses a chemical helper called a 'catalyst' to turn thick oils into lighter fuels, so the name helps you remember the machine's job.
