Since S-compounds in transportation fuels, such as
diesel, gasoline, and kerosene, are the main group of SO
emission sources, which results in health damage and air
pollution , more stringent standards of sulfur content
in transportation fuels are continuously being offered by
governments [2, 3]. Therefore, deep desulfurization of
fuels has been one of the most important research topics
in recent years . Hydrodesulfurization (HDS) is the
major method of desulfurization, the disadvantages of
HDS are higher temperature, higher pressure, larger
reactor volume, and more active catalysts, which can
result in plenty of cost and difﬁ cult to remove DBT and
their alkyl derivatives efﬁ ciently [5, 6]. Many efforts
have been made by researchers to obtain the effective
desulfurization methods of non-HDS desulfurization [7–
10], such as oxidative desulfurization (ODS), adsorption
desulfurization (ADS), extractive desulfurization (EDS),
ADS is one of the most attractive complementary
methods to HDS [ 11]. On the one hand, adsorption can
avoid solvent residual in transportation fuels, on the
other hand, most of the adsorbents also show excellent
desulfurization efﬁ ciency [12–14]. Various adsorbents
such as zeolites, activated carbons (ACs), met al oxides,
and clays have been studied for deep desulfurization.
Zn, Ni, and Ag etc. have been reported to use as active
components on various adsorbent supporters to get
higher efﬁ ciency [15, 16]. Among the different types of
based adsorbents have recently attracted
attention because of its π-complexation ability .
The RADS of Ni/ZnO nano-sorbent can produce
a cleaner gasoline and has been successfully applied.
The nano material for adsorption desulfurization is a
promising research direction. Only few studies focused
on nano material as adsorbent for the adsorption
desulfurization of transportation fuels. In this paper,
NiO supported on nanoscale Al
was used for
adsorption desulfurization. Particularly comparing the
real oil with the model fuel including kerosene, diesel,
DBT, 1-heptanethiol was a new point. Besides, effects
of various parameters on a sulfur adsorption capacity
(SAC) and selectivity of NiO/Al
-1 adsorbent were

Abstract—Desulfurization performance was
an adsorption model or real oil (diesel and kero-
at low temperature using nanocrystalline NiO/Al
in static equipment.
The properties of
adsorbent samples were characterized by BET surface areas, transmission electron microscopy,
FTIR spectra, and TG-DTG curves.
Desulfurization experimental results
the desulfurization ef-
ﬁ ciency for kerosene is much higher than that for diesel due to the π-electronic interaction and S–M bonds with
Also, a performance of adsorbent regeneration was kept well for multiple cycles.
