A recent study led by CHEN Xiangyuan from Guoneng Yulin Energy Co., Ltd. has shed light on the intricate processes involved in the low-temperature oxidation of coal, a phenomenon that holds significant implications for the construction sector. Published in the journal ‘矿业科学学报’ (Journal of Mining Science), this research utilizes advanced in-situ infrared experiments and quantum chemistry to unravel the transformation of active functional groups in coal, providing a clearer understanding of the underlying mechanisms that could influence coal’s behavior in various applications.
As the construction industry increasingly seeks sustainable energy sources, understanding coal’s oxidation processes becomes vital. The study reveals that during low-temperature oxidation, key functional groups such as —CH3 and —CH2— can transform into oxygen-containing groups like —CHO, —COOH, and —OH. This transformation is not merely academic; it has real-world implications for how coal is processed and utilized in energy production, potentially leading to more efficient combustion techniques.
“The reactions of key active functional groups in coal with O2 were found to be endothermic, requiring external heat input,” CHEN explains. This insight could guide engineers and energy producers in optimizing combustion conditions, thereby reducing emissions and increasing energy efficiency. Conversely, reactions with ·OH were found to be exothermic, suggesting that harnessing these processes could lead to more effective energy generation strategies.
The implications of this research extend beyond immediate energy applications. As construction projects increasingly prioritize sustainability and environmental responsibility, understanding the chemical pathways of coal oxidation may inform the development of new materials or energy systems that align with green building practices. By optimizing how coal is used, the construction sector can contribute to a more sustainable future while still relying on existing resources.
Furthermore, the quantum chemistry methods employed in this research, including structural optimization and intrinsic reaction coordinate computations, offer a robust framework for future studies. This could lead to the development of new technologies that enhance the efficiency and safety of coal usage in construction and other industries.
In a sector where innovation is crucial, the findings from CHEN’s research could pave the way for advancements that not only improve energy efficiency but also align with global sustainability goals. As the construction industry grapples with the challenges of climate change, studies like this one provide essential insights that could influence policy and practice in the years to come.
