1. have the method from the heavy residue hydrocarbon oil feed stream of the coke of delayed coking method for gasifying, it comprises:

  • A. grind the coke from delayed coking method, to produce the free-flowing material of the hydrocarbonaceous coke granule with predetermined ash oontent;

    B. by being incorporated in mobile fluid feed through the coke granule grinding, to form the fluidisation charging of pressurization;

    C., the incoming flow of residue hydrocarbon ils is provided;

    D. under the oxygen of predetermined amount exists, the fluid coke particle of merging ash oontent and the combustion chamber of residue hydrocarbon oil feed stream injection cold wall pipe shape wall membrane portions oxidation gasification reaction device of at least 2 % by weight will be there is;

    E. at the temperature of 900 ℃

    -1700 ℃ and

    the pressure operation gasifying reactor of 20-100bar;

    F. raw material is carried out to partial oxidation to produce hydrogen, carbon monoxide and slag material;

    G. from reactor, reclaim hydrogen and the carbon monoxide of synthetic gas form;

    H. the heat exchanger of hot synthetic gas being delivered to water-cooled is with cooling syngas;

    WithI. from heat exchanger reclaim high pressure steam, and by steam introduce turbine be used for generating.
