The methanol synthesis from coal leads to emissions of greenhouse gas and environmental pollutants. Approximately about kg of carbon dioxide is produced to synthesis 1 kg of methanol in the coalbased process, while the amount of produced carbon dioxide in the natural gasbased route is kg of carbon dioxide per 1 kg of methanol [9].
