Apart from the production of chemicalgrade methanol, the book deals briefly also with fuel methanol production, i. e. with the production of alcohol mixes. One of the many possible routes from coal to methanol is illustrated by a process flow diagram, and a material and energy balance is compiled for this typical example.

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 ...

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).

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 ...
