【3D Process Flow】Summary Post – Useful for understanding the process flow: https://bbs.hcbbs.com/thread-5711616-1-1.html ---------------------------------------------------------- The copper-13X molecular sieve composite adsorbent is first formed by the formation of copper thiolate complexes between copper ions and thiol compounds; thereafter, the 13X molecular sieve is used to adsorb heavier thiols. This approach enables the sulfur content in gasoline to be reduced to below 2 mg/kg, with no alkaline wastewater generated.
