Nanochemistry - 2

Cage-like carbon compounds are called fullerenes.

Fullerene is not a biological nanomaterial. 

Both aluminosilicates and alumina serve as catalysts in fluid catalytic cracking (FCC) units. Platinum is not typically used in cracking processes - it is more common in reforming reactions.

First-generation petrochemicals are basic building blocks like ethylene, propylene, butylene, and acetylene. Surfactants are specialty chemicals, not primary petrochemicals.

Hydrogen in hydrocracking removes heteroatoms (S, N, O) and saturates cracked products. Isomerisation is catalyzed by acid sites, not directly by hydrogen.

Isomerisation converts straight-chain alkanes to branched isomers. Branched hydrocarbons have higher octane numbers because they resist knocking better in combustion engines.

Both silica gel and bleaching clay are adsorbents used to remove impurities during purification. Ferric oxide (Fe2O3) is not used in absorption processes for crude oil.

Carbon nanotubes have a massive surface area for their size.
