Summary: Sulfur is the most abundant element in crude oil after carbon and hydrogen. The harmful effects of sulfur emissions from transportation fuels on the environment and human well-being are causing concern. In order to reduce these effects, regulatory agencies have set minimum allowable sulfur concentrations in transportation fuels. Adsorption desulfurization (ADS) process using activated carbon (AC) has gained attention due to its simplicity, effectiveness, and environmental friendliness. This review discusses the recent developments in ADS as a complementary process to traditional hydrodesulfurization (HDS) or as a standalone technique using AC.

Summary: The impact of the synthesis method on the properties of the Al2O3-Ga2O3 sample was investigated. Ga loading resulted in an increase in surface area and pore volume, but a decrease in pore size. XRD analysis confirmed the formation of γ-Al2O3 with Ga atoms incorporated into the structure. The adsorption affinity of the adsorbent was strongest for BT and weakest for DBT.

Summary: In this study, a simple protonation strategy was implemented to enhance the adsorption capability of Cu-N-C for desulfurization. The protonation not only increased the bonding strength between Cu-N-C and organosulfur but also reconstructed the positive electric field of Cu-N-C, resulting in accelerated mass transfer and higher adsorption kinetics. This research is of great significance for adsorption-related catalysis, separation, and purification.

Summary: A series of novel mixed metal oxides (MOs) were prepared as supports for Ni/MOs using the double hydrolysis technique. The desulfurization study showed that the 10%NiZnO-Al2O3 adsorbent exhibited superior desulfurization performance with a breakthrough point of 10 ppm in model gasoline. The superior desulfurization performance was attributed to its higher Lewis and Lewis/Bronsted acid site ratio, higher surface area, larger pore size distribution, and lesser amount of inactive ZnAl2O4 spinel.
