Coal Slurry - an overview ScienceDirect Topics

Coal gasification is operated for the syngas production from the coal slurry and oxygen in the gasifyer at a pressure of 5.6 MPa. The gasification temperature is about 1350 °C. Before the coal is fed to the gasifyer, it is crushed to the required particles sizes. The gasification reactions are shown in equations (1).

Coal-CO2 Slurry Feed for Pressurized Gasifiers: Slurry ...

2013-1-1  The CO2 slurry separated from the top of the mixing vessel has a low coal loading of about 20-25 weight-% (wt.-%), which, if fed directly to the gasifier, results in an excessively high CO2 recirculation in the system. The coal-CO2 slurry is hence concentrated before it is fed to the gasifier.
