Introduction. Catalytic coal gasification has been studied worldwide for nearly 20 years due to its advantages, such accelerating process rate, improving carbon conversion degree, reducing process temperature, and thus decreasing energy consumption and limiting mechanical problems due to moderate conditions in a gasifier, as well as achieving a desired gas composition (Huang et al., 2015).
