N2 - The coal/CH4-ZnO-Zn-H2O system has been proposed for the 2-step efficient chemical conversion system of the fossil fuels using a solar energy as the process heat and fossil fuel/ZnO redox system. The overall reaction is represented by CHx(coal) + CH4 + 2H2O(g) = 2CO + (4 + x/2)H2 The complete coal gasification to H2/CO gas mixture with the coal/ZnO redox system could be demonstrated with zero CO2 emissions at 1000-1100°C, eliminating the need to separate, while the steam gasification efficiency of coal remained 47% on a carbon basis. Zn-H2O reaction was conducted to generate H2 gas successfully. In the overall reaction, the product gas of the H2/CO mole ratio 2 could be obtained and can be directly used for synthesis of methanol and other chemicals.
