The selective preparation of monobenzyl glyceryl ethers, which are potential commodity chemicals with special functions, was explored to find new applications for glycerol. Among the acid catalysts investigated (sulfuric acid, heteropoly acid, Nafion(R), and zeolite), Zeolite Socony Mobil-5 (ZSM-5) afforded better results. The reaction of equimolar amounts of glycerol and benzyl alcohol at 150º...

• Zeolite ZSM-12 nanocrystals obtained using rigid diquaternary ammonium templates. Strong interaction between template and zeolite from solid-state NMR TGA. Significantly improved performance in n-C 16 hydroconversion methanol conversion. Fast desorption aromatics conversion shown by situ IR spectroscopy. is an important used as a catalyst several industrial hydrocarbon reactions. Facile synth...

Zeolites are microporous aluminosilicates with well-defined channels and cavities. They have been widely used as ionexchangers, molecular sieves, sorbents, and catalysts. The stability of zeolites is crucial to their applications. Many experimental and theoretical studies have been concentrated on their thermal stability. On the contrary, their behavior under external high pressures has receive...

The structure and reactivity of a room temperature stable zinc carbonyl complex in Zn-modified H-ZSM-5 zeolite were revealed by solid-state NMR spectroscopy.

A systematic study of two-staged upgrading process of vacuum residue for light fuel production has been carried out in a semi-batch binary reactor apparatus over Y, ZSM-5 and alkaline treated ZSM-5 zeolites. Prepared catalyst samples were characterized with XRD and BET. Density and Viscosity physical properties parameters estimation, as well as GC/SIMDIS analyses were conducted on liquid produc...

The catalytic fast pyrolysis (CFP) of bio-derived furans offers a promising approach for sustainable aromatic production. ZSM-5 modified by different metal species (Zn, Mo, Fe, and Ga) was employed in the CFP enhancing effects species, loadings, weight hourly space velocity (WHSV) on product distributions from 2-methylfuran (MF) were systemically investigated. It is found that introduction Zn, ...

The dynamics of carburization of Mo-oxo precursors exchanged onto H-ZSM-5 strongly influence initial induction periods and steady-state rates during catalytic pyrolysis of CH4 to alkenes and arenes at 900-1000 K. The effects of co-reactants and of activating conditions were examined by on-line time-resolved mass spectrometric analysis of effluent streams using rigorous analyses to account for e...
