The main operating purpose of thermal power plant is to provide steam for SNG production process. During coal combustion process, dominant carbon metabolic and subordinate hydrogen metabolic processes cause exergy destruction of MW, and generated carbon emissions and wastes result in exergy loss of MW.

Coal gasification is defined as the thermochemical conversion process in which coal is converted into gaseous products, including hydrogen and carbon monoxide. (49−51) This process aims to be an alternative to burning coal to reduce harmful emissions and increase the energy density of the fuel.

In this process, coalderived syngas can be replaced with renewable hydrogen, fully or partially. However, there is no such trial so far in the world using this technology. The first industrial application of this process was built in Kwinana, Western Australia, in the early 1980s with a production capacity of Mt/y pig iron (Orth et al., 2007).

DCL process concepts have been based on a variety of operating conditions and catalysts and can be performed in a single stage or two stages. In a typical single stage process, coal is contacted with hydrogen or with hydrogenated solvent at ca. 450 °C. The yield of fuel oil is about three barrels of oil/ton of coal with bituminous coals.

There are two main methods for hydrogen production from coal: coal coking and coal gasification. Hydrogen production from coal coking refers to coke oven gas containing 5560% H 2 produced in the process of retorting coke (Razzaq et al. 2013). The coke oven gas is separated and purified to obtain pure H 2. Coal gasification technologies for ...

Figure 6 shows that the price of hydrogen obtained by the coal gasification process could range between to /kgH 2 and steam reforming is as low as 1 to 2/kgH 2 on the world average. As an example, the capital expenditure (CAPEX) and operational expenditure (OPEX) requirements in China accounted for 8085% of the total cost.

The lower carbon to hydrogen ratio in coal relative to natural gas results in significantly higher direct CO 2 emissions from the process. The inventory data for both coal gasification routes (without and with CCS) are taken from the works by Ruthowski and Vickers, respectively [37], [38]. (4) C + 2 H 2 O ↔ CO 2 + 2 H 2.
