Amorphous Cr2WO6-Modified WO3 Nanowires with a Large Specific Surface Area and Rich Lewis Acid Sites: A Highly Efficient Catalyst for Oxidative Desulfurization

“…Figure d presents the Arrhenius lines of ODS toward three aromatic thiophene S sources, in which the slope corresponds to the value of E a / R . The E a values of ODS reaction for BT, DBT, and 4,6-DMDBT before 60 min reaction are 63.5, 55.4, and 61.3 kJ·mol –1 , respectively, suggesting that the DBT has the minimum E a and the reactivity order is DBT > 4,6-DMDBT > BT, which is comparable with some early reported efficient catalysts. , …”

Polyoxometalate-Based Poly(ionic liquid) as a Precursor for Superhydrophobic Magnetic Carbon Composite Catalysts toward Aerobic Oxidative Desulfurization

“…The reason may be that the nonporous or hydrophilic property of carriers resulted in the mass transfer barriers between solid and liquid phases. In order to avoid use of extra solvents, porous or two-dimensional carriers have been applied to adsorb sulfur compounds onto their surfaces, which could supply a microenvironment for oxidation. − Our strategy is to design a carbon-based superhydrophobic carrier for an increment of the contact between catalyst and fuel. However, this superhydrophobic catalyst may not do well in H 2 O 2 systems, while molecular oxygen (O 2 ) may be a promising candidate due to its abundant sources, low cost, and safety for use.…”

Hydroisomerization of 1-octene utilizing hierarchical SAPO-11-supported Ni catalysts: effect of the alkyl chain length of the mesoporogen

“…At the same time, microporous channels can easily cause carbon deposition and shorten the life of molecular sieve catalysts. 5,16–21 Recent research has demonstrated that the introduction of mesopores into SAPO-11 molecular sieves and the construction of a micropore-mesoporous hierarchical pore structure could effectively alleviate the diffusion limitation, reduce the selectivity of cracked products and improve the selectivity of isomers. 22–26 For example, Wen et al 22 reported that the Pt/SAPO-11 catalyst prepared with hierarchical SAPO-11 molecular sieves as a carrier has higher double-branched isomerization selectivity and lower cracking selectivity than the conventional microporous SAPO-11 molecular sieve in the hydroisomerization of alkanes.…”
