“…Under these locally extreme conditions, the hydroxyl radicals remove the sulfur from the organic phase without any catalyst, and additional oxidation compounds; [38] used a model fuel of n-octane or commercial diesel, thiophene, and n-octanol and was able to achieve almost complete desulfurization. The cavitation system only requires water as an additional chemical to the fuel (the use of additional oxidants as in [46] is currently excluded for technical implementation by the US patent [47]), with energy input only via the pump.…”

The use of pyrolysis oil can be seen as an alternative fuel for maritime transport. However, pyrolysis oil from tires must be desulfurized for this. Recently, this can be done by hydrodynamic cavitation. This process does not require oxidation chemicals but only water, a cavitation generator, and a pump to drive it. In the literature, this concept has been successfully tested on model fuels. In this study, the cavitation generator for the desulfurization of waste tire pyrolysis oil was printed from polylactic acid-based on simulations of the optimal design, which allows for much cheaper production and easy replacement in case of wear or testing of alternative designs. After 60 min of treatment at 5 bar inlet pressure, a desulfurization of almost 33% was achieved. Furthermore, an interaction analysis showed that only from a pyrolysis oil content of 5.5 to 6% does hydrodynamic cavitation have an effective effect on desulfurization.

“…The degradation is stimulated when HC is combined with other techniques such as various advanced oxidation processes (AOP) [4] , [11] . The phenomenon can also be utilized for more novel applications such as hydrodynamic cavitation assisted Oxidative Desulfurization (HCAOD) process [12] , [13] . Several researchers studied the degradation of Reactive Red 120 dye [14] , Coomassie Brilliant Blue [15] , Congo red [16] , reactive orange 4 dye [17] , imidacloprid [18] , commercial pesticide [19] , degradation of Acid Red 88 dye [20] were used the same dimensions of Venturi.…”

In this study, a particular type of thin film nano-composite membranes was prepared and used in the pervaporation process. The membranes were made of polyphenylsulfone and were coated with a thin layer of polydimethylsiloxane containing different amount of Cu-metal-organic framework (MOF) nano-structures. N-hexane containing dibenzothiophene was used as a model fuel. To characterize MOF and the prepared membranes, Fourier transform infrared, X-Ray diffraction, Brunauer-Emmett-Teller, field-emission scanning electron microscopy, water contact angle measurements, and thermogravimetric analysis were used. The effect of parameters such as sulfur content, process temperature, and Cu-MOF concentration on the membrane performance was evaluated. The results indicated that nano-composite membranes demonstrate a much better performance compared to the untreated membrane. The membrane containing 5 wt% Cu-MOF with a contact angle of 97° had more hydrophilic surface and proved the effect of the additive in improving the surface hydrophilicity. This membrane had the highest rate of flux and rejection (0.4 kg/m 2 h and 70%, respectively), and the lowest enrichment factor (0.3). As the temperature increased, the flux of M 4 membrane (with 5 wt% additive) increased, while the removal efficiency decreased significantly. The optimum temperature for desulfurization in the pervaporation process was obtained (50 °C).
