The adsorption and desorption of N2O on main-group ion-exchanged ZSM-5 was studied using temperature-programmed desorption (TPD) and density functional theory (DFT) calculations. TPD experiments were carried out to determine the desorbed temperature Tmax corresponding to the maximum mass intensity of N2O desorption peak and adsorption capacity of N2O on metal-ion-exchanged ZSM-5s. The results i...

Hierarchical micro-mesoporous ZSM-5 (MFI type) zeolite was synthesized by using corn plant stem pith powder from agricultural waste as hard template under simple hydrothermal method. The additional porosity generated this into the zeolites precursor gel yielded hierarchical (C-ZSM-5). Conventional micro porous (ConvZSM-5) also prepared same procedure without adding to compare catalytic performa...

The promotion of Ag–ZSM-5 by cerium for the selective catalytic reduction (SCR) of NO with methane in the presence of an excess of oxygen was studied in this work. Ce–Ag–ZSM-5 catalyzes the CH4-SCR of NOx over the temperature range of 450–600◦C. Rate measurements of NO reduction to N2 under SCR conditions and of the competing CH4 oxidation by O2 (CH4 combustion) show that incorporation of a sma...

The structure of a high-loading complex of ZSM-5 with 6.4 toluene molecules per unit cell has been determined by single-crystal X-ray diffraction. At least three kinds of toluene molecules were identified in the unit cell. Two disordered toluene molecules were located at the intersection of the straight and sinusoidal channels, the third in the sinusoidal channel. One (TOL1) of the two toluene ...

Abstract BACKGROUND The identification of new resources for producing biofuels and chemical‐based products is crucial processes sustainability. This study presents a valorization route to produce ethanol ethylene using cocoa's mucilage juice (MJ) residue from cocoa farms variety ‘Arriba’ (AC). processing parameters maximize the production subsequent selective conversion into were determined. Et...

Dehydroaromatization of methane (MDA) under non-oxidative conditions is a promising reaction for direct valorization natural gas and biogas. Typically, Fe-modified ZSM-5 catalysts display low aromatic productivity high coke selectivity in the MDA reaction. Herein, we show benefit starting from isomorphously substituted Fe-sites [Fe,Al]ZSM-5 zeolites prepared by hydrothermal synthesis. Upon calc...
