Synthesis of dimethyl ether from CO and H2

Thermodynamic conditions for synthesizing dimethyl ether from synthesis gas are determined. The optimum conditions of the process are as follow: T ∼ 300°C at p = 3 MPa for two catalysts loaded into the reactor: methanol synthesis catalyst (Katalco-58) and catalyst of methanol dehydration to dimethyl ether (γ-Al 2 O 3 ). The changes that occur with the catalysts during this process are demonstrated by electron scanning microscopy.
