Coal tar solution strong 1.25% / Cade oil 0.5% shampoo

As two important unconventional oil and gas resources, the in-situ pyrolysis technologies of tar-rich Coal and oil shale are key approaches to realize the clean and efficient utilization of resources, alleviate the contradiction between oil and gas supply and demand, and help achieve the “double carbon” goals. Both of them share the core characteristic of being rich in organic matter and convertible into oil and gas products through pyrolysis, yet they exhibit significant differences in resource endowments, pyrolysis characteristics and technological applications. This paper systematically combs the technical principles of in-situ pyrolysis for tar-rich Coal and oil shale, focuses on a comparative analysis of their similarities and differences in pyrolysis kinetics, process routes, key technologies and environmental impacts, and deeply analyzes the common bottlenecks and personalized challenges faced by the current in-situ pyrolysis technologies. It provides theoretical support and practical reference for the optimization and industrial promotion of in-situ pyrolysis technologies for tar-rich Coal and oil shale.
