ABSTRACT The utilization of coal resources is critically important in the modern era, and advancements in coal chemical technology are key to maximizing their value. Integrating modern coal chemical technology with the promotion of low‐carbon products is essential for achieving efficient coal resource utilization while supporting sustainable economic development. However, several challenges remain, including low conversion rates, high pollutant emissions, and insufficient residue reuse. Although researchers have made significant progress in addressing these issues, further in‐depth studies are needed to improve conversion efficiency, enhance gas recovery, and optimize secondary utilization of residues to ensure more sustainable development. The study systematically reviews advancements in traditional coal chemical technology and elaborates on the progress and advantages of modern coal chemical processes. Additionally, it highlights the pivotal role of carbon capture, utilization, and storage (CCUS) technologies in reshaping the energy structure. Furthermore, the reuse of coal chemical residues represents a crucial step forward in refining coal chemical technology. By addressing these aspects, this work serves as a reference for promoting cleaner and more efficient coal resource utilization.
