Stereolithography 3D printed monolithic catalyst for highly efficient oxidative desulfurization of fuels

Novel Method for Desulfurization of Mixed Fuel via Microbubble Oxidation Followed by Microtube Extraction

“…The HDS process has demonstrated efficacy in the removal of thiols, sulfides, and disulfides. On the other hand, the ODS process exhibits higher capability for the removal of HDS-refractory SCCs, specifically targeting benzothiophene (BT), dibenzothiophene (DBT), and their derivatives. , Therefore, ODS exhibits superior desulfurization capabilities in comparison with HDS when dealing with fuels containing high levels of these compounds. , …”

Towards unconstrained catalyst shaping: high accuracy DLP printing of porous γ-Al2O3-based catalysts

“…23 Although enormous progress in 3D printing of non-porous materials such as alumina, 13,24,25 titania 26 and zirconia 27,28 has been made in the recent five years, the same approach is not applicable to obtain porous pellets relevant for catalysis, because thermal sintering destroys the internal porosity of the catalyst material, reducing dramatically the specific surface area. 29 Pyrolysis at a lower temperature is an option that preserves the catalyst porosity; 30 however, the presence of carbon deposits on the final structure can be detrimental for catalytic applications.…”

Synergistic Catalysis of a PtFe-Alloyed Structure on W18O49 for Boosted Sulfide Oxidation

“…Sulfides in diesel fuel oil are a major pollutant, which will cause serious environmental pollution along with fuel combustion and have become the main trigger of acid rain and haze. − Ultradeep desulfurization of fuel oil is becoming increasingly important to slow environmental pollution. Among the various desulfurization technologies, oxidative desulfurization (ODS) has attracted extensive attention, owing to the highly efficient treatment capacity of aromatic sulfides. − The core reaction of ODS is the selective conversion of sulfides to sulfone derivatives in complex solvent systems .…”
