Due to the most recent environmental requirements, wide desulfurization has become an increasingly important way to obtain ultra-clean fuels for transportation of less than 15 ppmw of sulfur, such as diesel, gasoline, and jet fuel. as a result of the strict requirements for transportation fuels. ... role of surface acidity and textural properties,
While desulfurization processes using ionic liquids have been widely researched on the laboratory scale, few have comprehensively studied the feasibility of implementing ionic liquid-based desulfurization on an industrial scale. ... On the other hand, the role of respiratory viruses in the pathogenesis of severe respiratory infections is an ...
The DDS reaction is faster than the HYD. However, the HYD pathway becomes relatively fast with an increase in H 2 S and/or H 2 concentration in the reaction mixture; with an increase in methyl groups in the 4 or 4 and 6 …
Different sulfur compounds have different electron densities on the sulfur atoms, and steric hindrance plays important roles in desulfurization reactions 18. Therefore, it is necessary to research ...
From the experiments under different temperature, it can be found that NiO played an important role of desulfurization. However, the desulfurization mechanism of NiO need to be further researched. The reason of the initial reduction of sulfur removal under 300°C temperature may be that the sulfur compounds are physically adsorbed on the …
Complete and effective sulfur removal from liquid fuels is essential to meet the sulfur standard requirements. The oxidative desulfurization (ODS) process has been extensively used for the …
In the hydrometallurgical recycling process for lead–acid batteries, there are three desulphurization processes of lead pastes with oxalate, carbonate, and alkaline …
The rechargeable aqueous zinc-ion batteries (ZIBs) based on the Zn/MnO 2 couple and mildly acidic electrolyte have emerged as promising large-scale energy …
Combining desulfurization and fabrication of cathode materials for lithium–sulfur batteries (LSBs) can solve this issue with a double benefit. Herein, the amino-functionalized lotus …
Desulfurization is one of the important processes for the production of ammonia (NH3). The main purpose of this unit is to reduce the content of sulfur in natural gas. These values are obtained applying offline measurements in the laboratory and makes the process barely directly controllable. To estimate the sulfur, a development of data-driven based …
Desulfurization or desulphurisation is a chemical process for the removal of sulfur from a material. This involves either the removal of sulfur from a molecule (e.g. A=S → A:) or the removal of sulfur compounds from a mixture such as oil refinery streams. [1] using ...
The results of this work help establish the role of catalysts in the SCW process; demonstrate that modest desulfurization can be achieved in the absence of an external hydrogen source; and provide guidelines for catalyst selection. ... Hence, to understand the role of catalysis on SCW desulfurization, we performed a series of …
