Because
of destructive effects of organic chlorides, elimination
of these compounds from contaminated crude oil and its distillates
is very crucial for oil refiners. Despite the importance of the subject,
limited researches in this field are performed and most of the proposed
removal methods are operationally difficult and costly. In the present
study, an adsorption process as an efficient technology is proposed
and employed to eliminate the organic chlorides compounds from the
naphtha fraction of contaminated crude oil. The γ-Al2O3 nanoparticles as an adsorbent are prepared and characterized
by XRD, SEM–EDS, and BET analyses. Adsorption experiments are
carried out at different operating temperatures and also various initial
organic chloride concentrations. The experimental results indicated
that the adsorption efficiency reaches to more than 96%, when the
initial concentration of the organic chloride in the sample is 8.5
mg/L. The adsorption equilibrium analysis revealed that the Freundlich
isotherm model provided the best fit and prediction of experimental
data. It was also found that, for all of the verified samples, the
adsorption kinetics followed the pseudo-second-order equation well.
According to experimental investigations reported in the present work,
the sintered γ-Al2O3 nanoparticles would
be an effective adsorbent for elimination of organic chloride as a
hazardous material from the naphtha distillate of crude oil.
