Aromatics Technology

Aromatics Technology

Chevron Phillips Chemical’s Aromax® Technology is the premier on-purpose benzene production technology. This technology, paired with the appropriate feedstock, provides a superior ability to convert light hydrocarbons to aromatics and hydrogen. It is best suited to upgrade low-value feedstocks and/or for addressing a hydrogen (H2) shortage.


The Aromax® Process selectively converts light paraffins and naphthenes to hydrogen and aromatic products utilizing conventional fixed-bed reforming equipment. The following are fast facts about the Aromax® Process:

  • First reforming process based on a zeolitic catalyst
  • Best suited for converting C6–C8 hydrocarbons
  • Exceptional selectivity for converting C6 and C7 paraffins and naphthenes to benzene, toluene and hydrogen
  • Process includes a high-efficiency sulfur control system to eliminate catalyst poisoning by sulfur
  • Toluene extraction may or may not be required
  • Proprietary catalyst technology
