Desulfurization of diesel fuel with nickel boride in situ generated in an ionic liquid

Abstract

In order to improve the desulfurization efficiency, an ionic liquid (IL) was used as the solvent for the desulfurization of diesel fuel with nickel boride. The nickel boride prepared in IL-H 2 O showed high specific surface area. The desulfurization efficiency of model organosulfur compounds in this work was higher than that in the previous studies. The desulfurization reactivity of model organosulfur compounds followed the order of BT (DBT) > 3-MBT > 4,6-DMDBT. Furthermore, the products of model organosulfur compounds after desulfurization were analyzed by GC/MS and their corresponding reaction routes were proposed. The effectiveness of nickel salts followed the order of NiCl 2 (Ni(OAc) 2 ) > NiSO 4 > Ni(NO 3 ) 2 . The desulfurization efficiency of model diesel fuels reached 90.6% under the conditions of B/S molar ratio = 9, Ni(OAc) 2 /S molar ratio = 3, oil/IL volume ratio = 3, water content in IL = 5%, and reaction time = 50 min. ILs maintained their original structures after regeneration. Finally, the desulfurization of real diesel fuel was carried out and a desulfurization efficiency of 88.6% was obtained in 50 min. † Electronic supplementary information (ESI) available. See

Boron Nitride Mesoporous Nanowires with Doped Oxygen Atoms for the Remarkable Adsorption Desulfurization Performance from Fuels

“…As the isostructural to graphite, h-BN has aroused increased attention in recent years due to the outstanding physical and chemical properties. 17,18 h-BN is a layered structure comprising alternating boron and nitrogen atoms in a honeycomb arrangement, while the boron atoms are sp 2 hybridized with electron-deficient virtual orbitals. 19 h-BN is in the spotlight for applications as a filler for composites, in graphene-BN hybrid devices, a substrate for graphene electronics, and a support for catalysts.…”

“…With the increasingly stringent regulations and fuel specifications of the petroleum refining industry, the removal of sulfur compounds from fuels has brought about substantial research interest. − Among different desulfurization processes, adsorptive desulfurization (ADS) has been of particular concern owing to low-energy consumption. − Up to now, different adsorbents have been control-prepared in order to acquire high adsorption desulfurization performance, such as activated carbon, , Cu (or Ag)­(I)-containing adsorbents, − metal–organic frameworks (MOFs), , mesoporous silicon, , and so on. Besides, hexagonal boron nitride (h-BN) has been shown promising for adsorptive desulfurization.…”

One-pot extraction combined with metal-free photochemical aerobic oxidative desulfurization in deep eutectic solvent

“…8 Therefore, a more suitable method for deep desulfurization in moderate reaction environment is needed, and many energy-efficient and charge-effective technologies have been studied. [9][10][11] Compared with other non-HDS methods, such as adsorption desulfurization (ADS), [12][13][14] extraction desulfurization (EDS) [15][16][17] and biodesulfurization, 18 oxidative desulfurization (ODS) is one of the most promising methods due to its moderate reaction environment, high desulfurization and its ability to preserve the octane number compared to HDS. 5,[19][20][21] Many classical oxidants including oxygen, [21][22][23][24] hydrogen peroxide, [25][26][27][28][29] ozone 30,31 and organic hydroperoxide 32 have been reported, among which molecular oxygen (O 2 ) is the most green and low-cost oxidant.…”
