Removal of Mercury in Liquid Hydrocarbons using Zeolites Modified with Chitosan and Magnetic Iron Oxide Nanoparticles

Clinoptilolite zeolites were chemically modified with chitosan (Chit) and magnetic iron oxide nanoparticles (Fe3O4NPs) were synthesized for removal of mercury from liquid condensate hydrocarbon. The mercury content was in liquid hydrocarbon which was measured by Lumex mercury analyzer. The performance of sorbents based on zeolites modified chitosan and magnetic nanoparticles were examined on the real liquid condensate hydrocarbon. Removal of mercury using a prestine clinoptilolite zeolites, and zeolites modified chitosan (zeolites-Chit) were ~4.5, and ~35%, respectively. The effects of magnetic nanoparticles in zeolites-Chit sorbents were significant to reduce the mercury content in liquid condensate hydrocarbon which were from ~63 to ~66%. Increasing the mass ratio of Fe3O4 that influenced to the BET surface area of natural zeolites. Zeolites-Chit-Fe3O4NPs as an efficient sorbents are potential ideal to remove mercury in hydrocarbon for practical applications.
