Abstract

Sulfur content of under ground Waters and waste Waters from the refinerys should be reduced significantly before consumption. One remarkable process is Sulfurization/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank">Oxidative DeSulfurization. Sulfur compounds of the Water transform to sulfones and then get out of solution as a steam. In this work, Core-Shell Nickel-Molybden NanoParticles with sizes ranging from 55 to 100 nm were synthesized using successive reduction method and then, were deposited on γ-alumina support using wet impregnation method. This catalyst was characterized by UV-vis, SEM, EDS, TEM and XRD analysis. ODS of Water was conducted using the catalyst along with Hydrogen Peroxide as oxidant. 91. 2% of Sulfur content, was removed from the Water after 4 h of reaction at 60° C. The order of mentioned reaction was changeable between 1. 01 and 1. 27, the rate constant changeable between 0. 021 and 0. 05 min-1 on different temperatures. Catalyst’ s ability at 60° C got reduced about 30%, after two times of washing.
