Surface hydrophobicity and acidity effect on alumina catalyst in catalytic methanol dehydration reaction.

ABSTRACT:

Background

Methanol to dimethyl ether (MTD) is considered one of the main routes for the production of clean bio-fuel. The effect of copper loading on the catalytic performance of different phases of alumina that formed by calcination at two different temperatures was examined for the dehydration of methanol to dimethyl ether (DME).

Results

A range of Cu loadings of (1, 2, 4, 6, 10 and 15% Cu wt/wt) on Al₂O₃ calcined at 350 and 550 °C were prepared and characterized by TGA, XRD, BET, NH₃-TPD, TEM, H₂-TPR, SEM, EDX, XPS and DRIFT-Pyridine techniques. The prepared catalysts were used in a fixed bed reactor under reaction conditions in which the temperature ranged from 180-300 °C with weight hourly space velocity (WHSV) = 12.1 h^-
