Process Design and Analysis of Aromatics Production from Coal via Methanol with a High Yield. Producing aromatics from coal via methanol is a novel technology, which could mitigate the energy shortage in a petroleumpoor area. However, the selectivity of methanol to aromatics is merely 4070 wt % due to the byproducts of light hydrocarbons.
The coaltomethanol (CTM) is an important technical route for methanol production. The process suffers from high CO2 emission and low energy efficiency due to the mismatch of H/C (hydrogentocarbon) ratio between raw coal and products. Hydrogen production from renewable energy can be introduced into the system to meet the H/C ratio.
Conventionally, methanol is produced on industrial scale from synthesis gas "syngas," which is a combination of varying amounts of H 2, CO, and CO 2 frequently derived from gasified coal or natural gas ( Ott et al., 2012; Sheldon, 2017 ).
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 ...
Thermoeconomic analysis of methanol production process by CO 2 hydrogenation was carried out by considering the electrochemical hydrogen obtained from the proton exchange membrane (PEM) electrolyzer operating at 30 bar (Bellotti et al., 2019).This process was found potentially desirable to abate CO 2 emissions, but did not achieve economic feasibility due to the high cost of hydrogen production.
The coalbased process releases about kg CO 2 /kg methanol, and the natural gasbased process releases about kg CO 2 /kg methanol (Galindo Cifre and Badr, 2007, Rivarolo et al., 2016). Production of methanol from renewable sources reduces the intensity of fossil fuels as the main feed and also helps in mitigating CO 2 emissions ...
