“…Utilizing advanced and trustworthy steam power plant technologies, this technique will then supply green electricity just by swapping out a tiny bit of coal from a solid waste. So, overall CO 2 emissions from coal fired power stations can be reduced in a co-fired steam power plant 7 . Pakistan's energy policy needs to be adjusted and altered in order to make room for the usage of cleaner and local supplies 8 .…”

The potential of solid waste as an energy source is clear, owing to its wide availability and renewable properties, which provide a critical answer for energy security. This can be especially effective in reducing the environmental impact of fossil fuels. Countries that rely heavily on coal should examine alternatives such as electricity from solid waste to provide a constant energy supply while also contributing to atmospheric restoration. In this regards, Low Emissions Analysis Platform (LEAP) is used for simulation the entire energy system in Pakistan and forecasted its capital cost and future CO2 emissions in relation to the use of renewable and fossil fuel resources under the different growth rates of solid waste projects like 20%, 30% and 40% for the study period 2023–2053. The results revealed that, 1402.97 TWh units of energy are generated to meet the total energy demand of 1193.93 TWh until 2053. The share of solid waste based electricity in total energy mix is increasing from a mere 0.81% in 2023 to around 9.44% by 2053 under the 20% growth rate, which then increase to 39.67% by 2053 under the 30% growth rate and further increases to 78.33% by 2053 under the 40% growth rate. It is suggested that 40% growth rate for solid waste based electricity projects is suitable for Pakistan until 2053 because under this condition, renewable sources contributes 95.2% and fossil fuels contributed 4.47% in the total energy mix of Pakistan. Hence, CO2 emissions are reduced from 148.26 million metric tons to 35.46 million metric tons until 2053 but capital cost is increased from 13.23 b$ in 2023 to 363.11 b$ by 2053.

“…Therefore, it is essential to establish a rational coal molecular structure and explore the interaction mechanisms among coal and methane, carbon dioxide, and nitrogen (Ursueguía et al, 2021). Numerous researchers have interpreted the coal molecular structure model (CMSM) and characterized the carbon framework and functional groups through industrial analyses, elemental analyses, carbon nuclear magnetic resonance ( 13 C NMR) (Tursunov et al, 2020) spectroscopy, X-ray photoelectron spectroscopy (XPS) and attenuated total reflectance Fourier-transform infrared spectroscopy (FTIR) (Salmachi et al, 2023). Based on this, they reconstructed a coal molecular structure model (CMSM) and validated its correctness (Jia et al, 2023).…”

“…Starting from experiments and molecular simulations, scholars have done detailed studies on coal pyrolysis, − but rarely track the reaction paths of the unsaturated hydrocarbon products. Based on the Wiser bituminous molecular model which is generally recognized in the field and Hongqingliang (HQL) and Gaojialiang (GJL) molecular models which were built by us, here we use the ReaxFF module in AMS software to simulate the pyrolysis behavior of the models.…”

To study the generation rules of organic molecules or fragments and the generation paths of some hydrocarbon gases (C 2 H 2 /C 2 H 4 ) and inorganic gases (CO 2 /H 2 O/H 2 /H 2 S) in the pyrolysis process of bituminous coal at 1000–5000 K, the ReaxFF molecular dynamics module in AMS software was used to simulate the pyrolysis behavior of the Hongqingliang model, Gaojialiang model, and Wiser model. With the increase of temperature, the system potential energy decreases, the endothermic efficiency increases first and then decreases, the fragments of C 1 –C 4 fragments increase, and the gas molecules generated increase. In the pyrolysis process, the oxygen-containing functional groups and hydrogen groups formed H 2 O and H 2 with the increase of temperature. H 2 S as an intermediate product is always maintained in dynamic equilibrium. CO 2 comes from the decarboxylation of the carboxyl groups. When the temperature is lower than 3000 K, C 2 H 4 and C 2 H 2 are mainly formed by the adjacent carbon structure in coal molecules, and C 2 H 4 is formed from the ethyl side chain, the naphthenic structure, and the unstable aromatic rings. C 2 H 2 is formed from naphthene structures and aromatic rings with multiple side chains. When the temperature is higher than 3000 K, C 2 H 4 and C 2 H 2 are mainly formed by the random combination of free radicals generated by the crushing of coal molecules. The research results are of great significance to coal pyrolysis and clean utilization of coal.
