Petrochemicals from coal-derived syngas

摘要

The development of the Liquid Phase Dimethyl Ether (LPDME) process has established a means to effectively convert CO-rich syngas to dimethyl ether (DME) in a mechanically agitated slurry reactor.By operating in a dual catalyst mode,in-situ produced methanol may be converted to DME, thereby alleviating the chemical equilibrium limitation imposed on the methanol synthesis reaction.As a result,higher syngas conversions and methyl productivities are seen over methanol synthesis alone.
