Thermophilic biodesulfurization and its application in oil desulfurization

Abstract

To reduce the harm caused to the environment by fuel combustion and meet the increasingly stringent emission standards, the sulfur content of fuels should be reduced. Dibenzothiophene, benzothiophene, and their derivatives are sulfur-containing components of fuels that are difficult to desulfurize and can therefore cause great environmental damage. Biodesulfurization is a desulfurization method that has the advantage of being able to remove dibenzothiophene and its derivatives removed easily under conditions that are relatively mild when compared with hydrodesulfurization. This paper introduces the advantages of thermophilic biodesulfurization compared with mesophilic biodesulfurization; analyzes the desulfurization mechanism, including the desulfurization pathways and enzymic systems of desulfurization bacteria; and discusses the application of biodesulfurization in oil desulfurization. The main problems existing in biodesulfurization and possible solutions are also analyzed in this paper. Biological desulfurization is a promising method for desulfurization; accordingly, more studies investigating biodesulfurization of actual oil are needed to enable the industrialized application of biodesulfurization.

Synthesis of new nanocomposite based on nanoceramic and mono substituted polyoxometalate, PMo11Cd@MnFe2O4, with superior catalytic activity for oxidative desulfurization of real fuel

“…By increasing the polarity and molecular mass of these species, the separation will be possible either by extraction or adsorption. The feasible oxidants are hydrogen peroxide, [3,9] organic peroxides, [10,11] oxygen, [12,13] fenton's reagent, [14] ferrat, [15,16] and ozone. [17] Since hydrogen peroxide is inexpensive, environmentally friendly, highly reactive and produces neutral byproducts like H 2 O, it became the most preferred oxidant for the CODS processes.…”

The production of clean diesel fuel by facile sun light photocatalytic desulfurization process using Cd-based diacetate as a novel liquid photocatalyst

“…These different drawbacks make HDS poorly competitive (Javadli and de Klerk, 2012). Thus, many alternative desulfurization methods have been recently developed, such as adsorptive desulfurization (Hong et al, 2018;Jha et al, 2019;Ullah et al, 2019) and biodesulfurization (Chen et al, 2018;Etemadi et al, 2018). Extractive desulfurization (EDS) has also retained great attention for the last decade (Gao et al, 2018;Gutierrez et al, 2018).…”

A novel method for fuel oil desulphurization by deep eutectic solvent extraction coupled with reduction using sodium borohydride

“…Furthermore, this process is less effective for thiophenic sulphur compounds present in fuel oils such as benzothiophene (BT), dibenzothiophene (DBT), and their derivatives. [2] Therefore, an increasing amount of attention has been paid to develop alternative non-HDS methods such as extraction, [3][4][5][6] oxidation, [2,[7][8][9] adsorption, [10][11][12][13] biodesulphurization, [14,15] etc.…”
