Due to the advantages of Shell coal gasification process (SCGP): higher conversion efficiency of carbon and cold gas efficiency ,excellent environmental protection feature, high availability, and high flexibility to feedstocks, SCGP can be applied both for the revamping of existing ammonia plant and for new ammonia and rnelhanol plants.
The results show that with the increasing of temperature and pressure, the conversion of carbon and selectivity of DME are increased,and the selectivity of methanol is decreased. [
When the reaction temperature goes up to 1173K, to have the carbon conversion rate as 50%, it needs to cost 20 min, and the conversion rate be 60%, it needs to cost 26 min.
Because the reaction was controlled by thermodynamics and kinetics, at 3 MPa carbon conversion rate reached the peak at 533.15 K and was close to the carbon equilibrium conversion rate.
