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).

Introduction. Nowadays, coal gasification technology is being widely developed to keep up with the soaring energy demand [1], [2]. Partial replacement of H 2 O by CO 2 to realize the gasification of coal with H 2 O/CO 2 mixtures (cogasification) is an important approach that can allow for green, lowcarbon, and sustainable development [3]. Moreover, low temperature gasification should also be ...
