WebAromatics (benzene, toluene, xylene and ethylbenzene, or BTEX) are manufactured with a catalytic reforming process, which can be catalyzed by platinum ("platforming") or rhenium ("rheniforming"). Aromatics are either blended into gasoline, or distilled into pure individual compounds, which are the feedstocks for various plastics. 1. level 1.
