hydrocarbon cracking - 2026 ACF Regionals

Question

In a form of this process, spent catalysts are separated by cyclones then directed to a fluidized-bed regenerator where the coke is burnt off. For 10 points each:

[10m] Name this industrial process, whose “fluid catalytic” form uses faujasite-type zeolites bound to alumina matrices. This process breaks down long hydrocarbons into smaller chains.

ANSWER: hydrocarbon cracking [accept fluid catalytic cracking; prompt on oil refining]

[10h] Along with benzene and toluene, this compound comprises a group of aromatics generated from cracking or catalytic reforming. This compound is oxidized to generate terephthalic (“tair-uff-THAL-ick”) acid in the Amoco process.

ANSWER: xylene [accept mixed xylenes; accept para-xylene or p-xylene; accept meta-xylene or m-xylene; accept ortho-xylene or o-xylene; accept xylols; accept dimethylbenzene]

[10e] Catalytic reforming of naphtha generates this gas as a byproduct, which can then be recycled for cracking. This lightest diatomic gas is bubbled over palladium on carbon in a catalytic process for reducing alkenes to alkanes.

ANSWER: hydrogen [or H2; accept catalytic hydrogenation]
