Catalytic application of ferrierite nanocrystals in vapour-phase dehydration of methanol to dimethyl ether

Dehydration of Methanol to Dimethyl Ether Employing Modified H-ZSM-5 Catalysts

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...

Application of Novel Gamma Alumina Nano Structure for Preparation of Dimethyl ether from Methanol

In this study, preparation of nano-sized gamma alumina with high specific surface area and high yield by thereaction between aluminum nitrate and sodium carbonate, without using any surfactant is reported. Bohemite (Aluminum oxyhydroxide) was prepared as a precursor by strict control of pH and reaction temperature. The gel produced was purified by washing fol...

Catalytic consequences of acid strength in the conversion of methanol to dimethyl ether

0021-9517/$ see front matter 2010 Elsevier Inc. A doi:10.1016/j.jcat.2010.11.017 ⇑ Corresponding author. E-mail addresses: [email protected] (M. Neuro Iglesia). The effects of acid identity on CH3OH dehydration are examined here using density functional theory (DFT) estimates of acid strength (as deprotonation energies, DPE) and reaction energies, combined with rate data on Keggin polyoxometala...

Selective homogeneous and heterogeneous catalytic conversion of methanol/dimethyl ether to triptane.

The demand for specific fuels and chemical feed-stocks fluctuates, and as a result, logistical mismatches can occur in the supply of their precursor raw materials such as coal, biomass, crude oil, and methane. To overcome these challenges, industry requires a versatile and robust suite of conversion technologies, many of which are mediated by synthesis gas (CO + H(2)) or methanol/dimethyl ether...
