Abstract:

The existing process and technology need higher requirement of synthetic gas raw material, which causes the slightly higher cost for the downstream products. The utilization technology for low cost synthetic gas, especially for nitrogen containing synthetic gas is studied. The new technologies for dimethyl enther making with synthetic gas, F-T synthesis, low temperature liquid phase methanol synthesis etc. are described. The problems existing in the utilization of low cost synthetic gas, such as nitrogen containing synthetic gas are pointed out and its application foreground is prospected.
