1. the method for a brown coal microwave dehydration coupled gasification, it is characterised in that the step of described method is:

  • Step one, brown coal particle brown coal are crushed to particle diameter being 0.5mm ~ 50mm, more described brown coal particle is inserted microwave heating dewatering unit, dehydration is less than 10wt% to water content, obtains water vapour and dehydration brown coal particle;

    Step 2, dehydration brown coal particle step one obtained insert microwave heating installation, then under 600 ~ 1500 DEG C of conditions, the water vapour that step one is obtained lead to from the bottom of microwave heating installation into, lead to into water vapour and the dehydration brown coal particle of heating carry out gasification reaction, obtain gasification coal gas.
