The production of methanol only from coal has an estimated efficiency of 41 to 55 percent; but if methane and coal liquids are produced simultaneously, the overall process efficiency can climb to 75 percent. Waste and wood can also be used as energy sources. Conversion from these sources to methanol is likely to be somewhat less efficient ...

The process. Methanol is an intermediate for the coaltoolefins (CTO) process and a direct feedstock for the methanoltoolefins (MTO) process. To produce the methanol intermediate for the CTO process, coal gasification produces syngas (carbon monoxide), which is then converted to methanol by traditional technologies.

The coaltomethanol process can be divided into four major cost areas: coal purchase, coal gasification, gas preparation, and methanol synthesis. The contribution to the plantgate cost was estimated for each area except for coal purchase by dividing the plant capital and operating costs among the areas and calculating a product price for each.

The traditional polygeneration process of coaltomethanol/power is shown in Fig. 1 [3]. Coal is converted into the crude syngas in the gasifier. After heat recovery and scrubbing, the crude syngas is separated into two parts. One part is sent for water gas shift (WGS) unit and then mixed with a part of unshifted syngas for methanol synthesis.

Several aspects of the process for producing methanol from syngas are different from those needed when using a pure source of CO 2 and H example, the formation of methanol from CO is based on CO reacting directly with H 2 to produce CH 3 OH; the conversion is significantly more exothermic at− kJ/mol relative to Reaction 2 above (Ott et al., 2012).

Gasification is a thermochemical process for the conversion of a solid organic material, typically coal or biomass, into syngas. From a chemical point of view, gasification occurs due to the partial oxidation of a solid material at temperatures of 700900 °C by means of a gasifyingoxidant agent, such as air, oxygen, steam or carbon dioxide.
