Sub-Product

Benzene, Toluene, and Xylenes can be made by various processes. However, most BTX Production is based on the Recovery of Aromatics derived from the Catalytic Reforming of Naphtha in a Petroleum Refinery. Catalytic Reforming usually utilizes a Feedstock Naphtha that contains Non-Aromatic Hydrocarbons with 6 to 12 Carbon Atoms and typically produces a Reformate product containing C6 to C8 Aromatics (Benzene, Toluene, Xylenes) as well as Paraffins and Heavier Aromatics containing 9 to 12 carbon atoms. Another process for producing BTX Aromatics involves the Steam Cracking of Hydrocarbons which typically produces a Cracked Naphtha product commonly referred to as Pyrolysis Gasoline, Pyrolysis Gas or Pygas. The Pyrolysis Gasoline typically consists of C6 to C8 Aromatics, heavier Aromatics containing 9 to 12 Carbon atoms, and Non-Aromatic Cyclic Hydrocarbons (Naphthenes) containing 6 or more Carbon Atoms.
