Developing a laboratory scale or pilot scale chemical process into industrial scale is not trivial. The direct conversion of CO2 to methanol, and concomitant production of hydrogen from water electrolysis on large scale, are no exception. However, when successful, there are certain benefits to this process over the conventional process for producing methanol, both economic and environmental ...

In the process simulation, two reactors were employed due to low conversion of the CO 2 hydrogenation reaction. Figure 1 represents the process flow diagram of methanol production via CO 2 hydrogenation (Wiesberg et al., 2016).In this process, the feed of 1,000 kmoles per hour of carbon dioxide at 40°C and 20 bar was mixed with the 3,000 kmoles per hour of hydrogen (at the same conditions).

Toluene methylation using methanol offers a high potential molecular engineering process to produce pxylene (PX) based on shapeselective catalysts. To further improve the process economics, a novel short process was proposed by reducing the highenergy consumption separation of xylene isomers in existing processes since the PX selectivity of the xylene isomers can be enhanced more than the ...

For coalbased methanol production, coal is intermingled with O 2 of AS and subsequently subjected to CG for producing crude syngas. The cryogenic separation technology is primarily used in the AS for oxygen production, which is a high energy consumption process (Xiang et al., 2014).Because of the small hydrogentocarbon (H/C) ratio in coal, WGS process is used to convert CO and H 2 O to CO 2 ...

The process flow of Route 3 is similar to that of Route 1 . Route 3 uses a coelectrolysis unit and a MeOHsynthesis unit. In the coelectrolysis unit, steam and CO 2 are reduced to syngas by the SOEC after pressurization (up to ~ MPa). The syngas is then sent to the methanolsynthesis unit and converted to MeOH.
