Compared to conventional methods, coal gasification process has a positive effect on human life and nature by reducing air pollution. After the coal gasification process, the products (tar, NOx, SOx, dioxins, furans, hydrocarbons and CO) leaving the reactor should be checked before discharging into ambient air [116, 117]. Solid wastes released ...
