“…Nickel-based catalysts for HDS and alkylation desulfurization also attracted much attention. Yin et al − synthesized a catalyst with the formula of porous ammonium NiMo for deep HDS, and they also studied the formation and removal of sulfur elements in ultralow-sulfur gasoline. Li et al − studied and improved a catalyst for alkylation desulfurization of FCC gasoline.…”

A high-performance Ni/ZnO–Al2O3–SiO2 adsorbent was developed for reactive adsorption desulfurization (RADS) of diesel. The desulfurization performance of the prepared adsorbents was evaluated in a fixed-bed reactor for treating a hydrotreated diesel with a sulfur content of 1187 ppm. The preparation conditions were investigated, such as aging time, aging temperature, metallic ion concentration, and precipitation temperature. Results showed that the adsorbents performed at a high desulfurization efficiency under the mild preparation conditions. This indicated that smaller crystalline grains were favorable for desulfurization over the Ni/ZnO–Al2O3–SiO2 adsorbent. The adsorbent attained a high adsorption ability of 38.4 mg/g at a breakthrough sulfur level of 20 ppm. The mechanism of deactivation of the adsorbent was also studied and discussed by various characterizations, such as N2 physisorption, powder X-ray diffraction (XRD), ammonia temperature-programmed desorption (NH3–TPD), transmission electron microscopy (TEM), and scanning electron microscopy/energy-dispersive spectrometry (SEM/EDS). The main reasons of the deactivation of the RADS adsorbent include the carbon deposition, the formation of ZnS, and the sintering of the active and support.

“…Mercaptan and thioether compounds are mainly concentrated in the light distillate of FCC gasoline, while thiophene compounds are in the heavy cut. As the boiling point increases, mercaptan and thioether compounds decrease. − This follows the same trend of olefin compounds: the higher the boiling point, the fewer are the olefins. The most popular process for FCC gasoline desulfurization is hydrodesulfurization (HDS).…”

Desulfurization of a fluid catalytic cracking (FCC) gasoline by extractive distillation was investigated. A modified Ellis dual-circulating vapor–liquid distiller was used to measure vapor–liquid equilibrium data of the FCC gasoline and various solvents. N-Formyl morpholine (NFM) was selected as the solvent for extractive distillation desulfurization. The desulfurization effect of FCC gasoline was investigated on a continuous extractive distillation column. At the optimal conditions, the distillate yield reached to 64.18 vol %, and sulfur content was 26.03 mg·L–1. After that, the heavy fraction was hydrodesulfurized on a FGH-31 catalyst in a fixed bed reactor. Results showed that the sulfur compounds in the heavy cut could be reduced to 9.5 mg·L–1. Light fraction of the extractive distillation and the hydrodesulfurized heavy cut are of primer blending compounds for producing low sulfur gasoline.

“…The presence of impurities like sulfur‐ and nitrogen‐containing compounds (NCCs and SCCs) adversely affect fuel efficiency and cause environmental pollution. [ 21 ] Moreover, these compounds can poison catalysts during combustion. Therefore, the impurities are required to be removed to produce cleaner liquid fuels.…”

In the last two decades, metal−organic frameworks (MOFs) have attracted overwhelming attention. With readily tunable structures and functionalities, MOFs offer an unprecedentedly vast degree of design flexibility from enormous number of inorganic and organic building blocks or via postsynthetic modification to produce functional nanoporous materials. A large extent of experimental and computational studies of MOFs have been focused on gas phase applications, particularly the storage of low‐carbon footprint energy carriers and the separation of CO2‐containing gas mixtures. With progressive success in the synthesis of water‐ and solvent‐resistant MOFs over the past several years, the increasingly active exploration of MOFs has been witnessed for widespread liquid phase applications such as liquid fuel purification, aromatics separation, water treatment, solvent recovery, chemical sensing, chiral separation, drug delivery, biomolecule encapsulation and separation. At this juncture, the recent experimental and computational studies are summarized herein for these multifaceted liquid phase applications to demonstrate the rapid advance in this burgeoning field. The challenges and opportunities moving from laboratory scale towards practical applications are discussed.
