Aromatics are major building blocks of polymers, or plastics, that turn up as everything from PET bottles for water to breathable, wrinkle-resistant polyester clothing. These petrochemicals comprise a specialized, value-added sector of the energy industry. The process for refining crude oil into useful aromatic streams for derivative use often involves the usage of a catalyst to facilitate chemical reactions. Among the various types of catalysts, many are zeolites—porous aluminosilicates—such as ZSM-5, a unique synthetic zeolite prolifically used in the upgrading of chemicals in alkylation and isomerization. Petrochemicals producers are constantly looking to minimize overhead costs to weather the volatility in commodity markets and provide a competitive end product to the average person.
