Problems solved by technology

At present, coal pyrolysis technology mainly includes ground pyrolysis technology and in-situ pyrolysis technology. Although ground pyrolysis technology can improve the utilization rate of coal resources and reduce carbon emissions, it requires a lot of manpower and material resources during mining and transportation. And there are certain risks; in-situ pyrolysis technology avoids the loss of coal during transportation, and has greater advantages in the green and low-carbon development and utilization of coal
[0004] Most of the existing pyrolysis technologies focus on the production and conversion rate of oil and gas after coal pyrolysis, but lack of dynamic monitoring and mechanism research on real-time high-temperature damage of coal during pyrolysis

Description

technical field [0001] The invention belongs to the technical field of oil-rich coal development, in particular to a device and method for real-time monitoring of oil-rich coal pyrolysis. Background technique [0002] Green mining and efficient utilization of coal have gradually become important measures to ensure national energy security. Oil-rich coal is a coal resource that integrates the properties of coal, oil and gas. Compared with traditional coal resources, it has the characteristics of greater development potential, higher conversion rate of oil and gas, and lower mining and utilization costs. Based on the status of my country's coal as the main energy source and the huge potential of substitute oil and gas supply, re-examine the existing coal utilization methods and development technologies, realize the transformation of oil-rich coal from coal resources to coal-based oil and gas resources, and accelerate the research on oil-rich coal development and utilization te...
