AB  - Carbide slag may pollute the environment because it is difficult to handle. In 
      this paper, carbide slag without pretreatment served as the new source of calcium 
      and was added to bituminous coal for gasification experiments to realize waste 
      utilization. The gasification experiment after adding carbide slag to bituminous 
      coal enhances H(2) production, which reduced the activation energy of the 
      gasification reaction. The results show that the catalytic effect on steam 
      gasification was evident when the carbide slag was added to Mongolian bituminous 
      coal. The coal char at reaction temperature was prepared and characterized by 
      X-ray diffraction (XRD), Raman, Scanning electron microscope (SEM), Transmission 
      electron microscope (TEM), X-ray photoelectron spectroscopy (XPS), and FT-IR 
      spectroscopy. The carbon structure evolution and calcium structure changes of 
      coal char under reaction temperature were studied, and the influence of coal char 
      structure changes on gasification performance was analyzed. The results show that 
      in the coal char added with carbide slag, the oxygen-containing functional groups 
      generated by the polycondensation reaction interacted with calcium to form a 
      calcium-oxygen-carbon complex. The existence of this structure not only leads to 
      the highly uniform dispersion of CaO in the char but also hinders the 
      graphitization process of the char. Highly dispersed CaO and disordered carbon 
      structure significantly improved the reactivity of bituminous coal steam 
      gasification. Si and Al in the bituminous coal affected the dispersion of Ca 
      during steam gasification.
