Abstract: The present disclosure belongs to the technical field of clean and efficient mining of deep unconventional or conventional resources, and discloses a pilot-scale supercritical water oxidation oil and hydrogen production system capable of realizing long-distance multi-stage heating of organic rock. The system comprises a supercritical water generator, a supercritical water pyrolysis reaction system for organic rock, an oxygen injection system and an oil-gas condensation and collection system, wherein the supercritical water generator mainly comprises a water injection system, a front-section preheating reaction system, a second-stage heating system and a third-stage heating system. The reaction system can carry out a pilot-scale simulation process of supercritical water pyrolysis for organic rock, a multi-stage heating function is realized, the maximum reaction distance is 8 m or more, and the release characteristics of oil-gas products under different reaction distances are explained. Meanwhile, the parameters of high-temperature residual carbon oxygenation hydrogen production are obtained, and the supercritical water oxidation oil and hydrogen production process of long-distance multi-stage heating of organic rock is completely simulated.

Abstract: An integrated device and a method for continuously capturing, storing and separating a flue gas in an underground rock stratum are provided. An injection well, a monitoring well and an emission well are arranged in sequence at locations from near to far from a flue gas emission source. The injection well, the monitoring well and the emission well are respectively drilled to different depths in a storage rock stratum. A horizontal injection channel is arranged at bottom end of the injection well. During migrating the flue gas in the storage rock stratum, CO2 and sulfur nitride are absorbed by a rock porous medium and gradually enriched, and meanwhile, the CO2 and sulfur nitride, after chemically reacting with water, minerals and biomass in a rock, are gradually mineralized to achieve storage; and separated N2 is gradually migrated upwards to the emission well to achieve separation.
