Study on the Technology of Synthesis Dimethyl Ether with Bi-Function Catalyst by Phophorus Modified

Abstract:

The factor and technology of synthsis dimethyl ether by one step method were studied in slurry reactor with bi-function catalyst by phophorus modified (C301/ P-γ-Al₂O₃) and liquid paraffin. The results showed that the temperature, pressure, space velocity of reaction system and CO₂ content in the syngas have a greater influenced to synthsis dimethyl ether. The CO conversion per pass reached 93% and DME selective was more than 60% at 150mL liquid paraffin catalyst for solvent quality of 7.3%, H₂ (mol) to CO (mol) of 2, 270°C, 4.3MPa, space velocity of 600mL/h·g_cat. The existence of CO₂ in the syngas improved the produce yield of dimethyl ether.
