Chen, Y.-H.; Wong, D.S.-H.; Chen, Y.-C.; Chang, C.-M.; Chang, H. Design and Performance Comparison of Methanol Production Processes with Carbon Dioxide Utilization. Today, with the exception of China, which uses coal to produce methanol, other parts of the world use cheap natural gas as feed to produce methanol. Methane (the main element of natural gas) participates in the equilibrium reaction with steam and the product of the reaction is mainly hydrogen and carbon monoxide during reaction (3): In addition to methane, other hydrocarbons can also produce hydrogen in response to water vapor conversion. In this cycle, the required hydrogen is produced completely independent of fossil fuels and using electrolysis. Faced with the costly problem of waste disposal and the need for more energy, a growing number of countries are turning to gasification, a time-tested and environmentally-sound way of converting the energy in municipal solid waste, MSW, into useful products such as electricity, fertilizers, transportation fuels and chemicals.
