But the retirement process of coal will slow down this year, and the low price of coal will make the CTL process more costeffective than other sustainable energy sources [38]. And many researchers have shown that the synfuels produced through the FischerTropsch process are equally efficient as crude oils and a clean source of energy.

A different type of ICL process involving methanol is the gasification of coal followed by conversion to methanol and subsequent conversion of methanol to a marketable gasoline product. A 100,000 ton/year MTG process plant was started in China's Jincheng, Shanxi province, in 2009, as part of a CTL demonstration complex.

Based on the analysis, we identify that the coaltomethanol process consumes a vast amount of water and energy with significant CO 2 /SO 2 /NO x emissions. For water/energy savings, methanoltoolefins process is of litter potential because its consumptions are mainly the indirect ones. The negative effects of CCS should be noticed for the ...

methanol (CH 3 OH), the simplest of a long series of organic compounds called alcohols, consisting of a methyl group (CH 3) linked with a hydroxy group (OH). Methanol was formerly produced by the destructive distillation of wood. The modern method of preparing methanol is based on the direct combination of carbon monoxide gas and hydrogen in the presence of a catalyst.

Also, CO 2 may form through WGS (WaterGas Shift) reaction (eq. (4)) [ 15 ]. This reaction is usually used to adjust the CO 2 /H 2 ratio in the feed for the methanol synthesis reaction [ 40 ]. The latter process is usually performed at 250300 °C, 510 MPa, in the presence of CuO/ZnO/Al 2 O 3 as a catalyst [ 15 ].
