1. a carbonaceous material dry powder gasification process, is characterized in that:

  • comprise the following steps;

    I) carbonaceous material and oxygen containing vaporized chemical generating gasification are reacted, to generate main component be the crude synthesis gas of CO and H2 and main component is the lime-ash of inorganics;

    Ii) part crude synthesis gas and the descending cooling and purifying of most of lime-ash, the crude synthesis gas through ash disposal of lowering the temperature is sent to follow-up flow process, and the lime-ash through quenching is discharged through slag notch;

    Rest part crude synthesis gas and flying dust up with cooling material hybrid cooling, then enter hypothermic response section, the carbon carrying out non-complete reaction reacts with the vaporized chemical supplemented;

    Reacted crude synthesis gas and flying dust are through cooling, purification, and the flying dust in removing crude synthesis gas, clean low temperature crude synthesis gas is sent to follow-up flow process.
