Fig. 1 shows that the coal gasification technology route based on concentrated solardriven is comprehensively in line with the global demand for carbon neutrality. This route has a broad prospect and essential strategic value. Thermodynamic analysis of solar catalytic gasification is an important part of the chemical process.
