Mechanistic Insights into the Desorption of Methanol and Dimethyl Ether Over ZSM-5 Catalysts

The desorption of methanol and dimethyl ether has been studied over fresh and hydrocarbon-occluded ZSM-5 catalysts with Si/Al ratios of 25, 36 and 135 using a temporal analysis of products reactor. The catalysts were characterized by XRD, SEM, N2 physisorption and pyridine FT-IR. The crystal size increases with Si/Al ratio from 0.10 to 0.78 μm. The kinetic parameters were obtained using the Red...

Conversion of Methanol on CuO/H-MOR and CuO/H-ZSM-5 Catalysts.

This paper deals with maximizing dimethyl ether (DME) production from methanol due to its industrial importance as a future diesel fuel. The high acidity and the micro-porous structure of the catalysts encouraged this reaction. Catalysts containg 6% CuO supported on H-ZSM-5 and H-MOR zeolites give high activities for DME production. The 6% CuO/HMOR is more selective for DME production, while th...

Acidity Characterization of H-zsm-5 Catalysts Modified by Pre-coking and Silylation

A comprehensive study on the acidic and coking properties of selectivated H-ZSM-5 catalysts during xylene isomerization has been made. The effects of surface modification by pre-coking and silylation on the nature and location of carbonaceous deposits and on related acidic features of the spent catalysts were respectively characterized by Xe NMR of adsorbed Xe and solid-state P MAS NMR of adsor...

Continuous selective oxidation of methane to methanol over Cu - and Fe - modified ZSM - 5 catalysts in a flow reactor

The selective oxidation of methane to methanol is a key challenge in catalysis. Iron and copper modified ZSM-5 catalysts are shown to be effective for this reaction using H2O2 as the oxidant under continuous flow operation. Co-impregnation of ZSM-5 with Fe and Cu by chemical vapour impregnation yielded catalysts that showed high selectivity to methanol (> 92% selectivity, 0.5 % conversion), as ...

Process simulation of dimethyl ether synthesis via methanol vapor phase dehydration

The production processes included catalytic dehydration of methanol in an adiabatic fixed-bed reactor and two columns product separations. In this study, the technological process for dimethyl ether (DME) synthesis is built on PRO/II platform based on the combined parameters of the reaction dynamic model for methanol dehydration reaction, the improved NRTL model of the liquid phase, the PR mode...
