“…Recently, nickel and cobalt nano-particles for the HDS process have been described and reported that Ni outperforms cobalt nano-particles in terms of efficiency [84]. Carbon nano-tubes were also evaluated as carriers for the HDS catalyst, and the results revealed that the sulfur content in the products decreased from 1126 mg/L to less than 10 mg/L [85]. Petzold et al [86] Described nickel supported on zinc-oxide nano-wires as an HDS catalyst.…”

The production of clean liquid fuels is critical to maintaining a healthy life and environment around the world. To meet the new sulfur standard requirements, sulfur compounds must be effectively and completely removed from fuel oil. Therefore, researchers' attention turned to research into different techniques to remove sulfur from kerosene. This review focused on discussing a variety of catalysis approaches and emerging technologies for ultra-deep desulfurization of refinery streams for ultralow sulfur, such as hydrodesulfurization, catalytic-oxidative desulfurization, and adsorption desulfurization to form clean liquid fuels. This review discusses the most important industrial parameters that influence sulfur removal processes and has focused primarily on the main role of the catalyst and its type in impacting the efficiency of the process. Also, it will discuss the concepts of nano-catalysts, their preparation methods, and the most common forms, were described such as graphene, carbon nano-tubes (CNTs), metal-organic frames (MOVs), and zeolites. A comparison between the nano-catalyst and the conventional catalyst was also discussed to show the great effect of the nano-catalyst in improving the removal processes, which will lead to the development of innovative, efficient desulfurization methods that produce zero-sulfur fuels. In addition, understanding the most important challenges in nano-catalysts.

“…Single-walled carbon nanotubes (SWCNTs) have recently been used as a support for Ni and yttrium metals, which were deposited via an arc discharge method. Higher HDS activity was specifically observed when the Ni-Y/SWCNTs are oxidized by heat treatment at 200 °C . Single-layered nanocatalysts of CoMo supported on carbon nanotubes were also reported to have high HDS activity, with the support properties inhibiting the formation of undesirable CoS 2 phases .…”

Proliferating energy consumption, particularly of fossil fuels, has led to an increasing generation of pollutants; many of these harmful products have been of serious environmental concern. While energy demand will continue to grow due to massive urbanization and industrialization, the ability to remove such pollutants has not yet been achieved. Therefore, policies are always being reviewed to accommodate the existing reality of minimizing the amount of pollutants released to the environment on a daily basis. Sulfur dioxide, a major environmental pollutant, gets to the environment through the combustion of sulfur-containing fuel in the engine of automobiles. Over the years, regulatory bodies such as the European Emission Standard have set limits to the amount of sulfur in transportation fuel to safeguard the environment. Lately, the limit for clean fuel specification with respect to sulfur content is set to nearly zero ppm. This policy came at a time when crude oil experienced a large decline in price, in addition to increased sulfur content and daily fluctuations of crude density. Compliance with this tight regulation will mean that refineries are expected to either modify their hydrotreating unit, which is capital intensive, or adopt robust catalysts, through research, that can work in tandem with the existing conventional hydrotreating catalysts to reduce the sulfur level to the required limit. This urgent demand has once more drawn the attention of the scientific community. Since there has been a great stock of research outcomes with respect to catalysts for hydrodesulfurization application in recent times, our aim is to collect and review those recent articles on hydrodesulfurization catalyst design and development. The tutorial review is therefore intended to cover a basic hydrodesulfurization overview, followed by detailed discussions on the recent development in the choice of active phases, their supports, and synthesis strategies. The work is expected to guide researchers, especially beginners that are interested in refinery hydrotreatment, on the recent development in hydrodesulfurization catalyst design and development.

“…Because the catalytic activity is intimately related to the physicochemical properties of the support, the design of catalysts arouses much interest of researchers; therefore, some novel silicon-based (SBA-15, FDU-12, MCFs) and carbon-based (activated carbon, carbon nanotubes) catalysts were successfully synthesized and utilized. − Although their tunable pore structures and high specific surface areas seemed beneficial to the reaction performance, the poor mechanical strength and high cost as well as regeneration problem still remained being solved …”

Zr modified mesoporous alumina Al-TUD-1 with different Zr content was successfully synthesized via sol− gel method and the optimal thermal treatment time was 4 h. The characterization results of HRTEM, XPS and pyridine FT-IR revealed that Zr atoms acted as electronic promoters not only enhanced the sulfidation degree and modulated the morphology of MoS 2 active phases but also brought more acidities into the alumina framework. Additionally, the sulfided catalysts were evaluated using dibenzothiophene (DBT) and FCC diesel as feedstocks, respectively. NiMo/ZrAT-100 catalyst with the largest pore size, the highest active metal sulfidities, as well as the highest total acid and B/L value exhibited the highest HDS (99.1%) and HDN efficiencies (98.7%) in diesel hydrotreating reaction; moreover, it possessed the largest reaction rate constant in DBT HDS reaction. Furthermore, a possible reaction network was also proposed, in which DDS route was the predominant pathway for DBT HDS.
