The process of Coal-methanol Through the Carbonmonoxide shift reaction to adjust the synthesis gas of the carbon-hydrogen ratio appropriatefor the synthesis of methanol to provide carbon-hydrogen ratio and thus obtain a higher yieldof methanol first after the Carbon monoxide shift reaction so that it easilyremoved into Carbon dioxide and methanol synthesis required for hydrogen. The designselected temperature sulfur-tolerant part of transformation in technology the advantage is toreduce the desulfurization process to reduce device power consumption to save the cost. First of all carried out a feasibility analysis of the entire methanol plant design Secondly
