Study on synthesis of dimethyl ether from syngas obtained by biomass gasification

摘要

Dimethyl ether (DME) has aroused a great interest all over the world due to its potential use as multi-purpose fuel. A new technical route of pseudo-one-step synthesis was proposed to produce DME. The characteristics of pseudo-one-step synthesis for DME from syngas obtained by biomass gasification have been investigated. The effects of top and bottom temperature and the temperature control method on the catalytic performance in DME synthesis were discussed. A comparison research between syngas derived from biomass gasification and syngas without CO2 for DME production was carried out.
