Shale Hydrogen Generation Experimental Device, Experimental Method and Analysis Method

Abstract

The invention provides a shale hydrogen generation experimental device, an experimental method and an analysis method, which belong to the technical field of energy and chemical industry. Both the non-recyclable shale reaction space and the recyclable shale reaction space are installed on the base; the annular heating wall- Correspondingly surround the non-recoverable shale reaction space and the recyclable shale reaction space; the helium tank is connected with the non-recoverable shale reaction space and the recyclable shale reaction space one by one; the gas collection bag is connected with multiple recyclable shale reaction spaces The reaction space is connected, and both the non-recoverable shale reaction space and the recoverable shale reaction space are connected to the gas chromatograph-mass spectrometer. The shale hydrogen generation experimental device, experimental method and analysis method provided by the present invention realize the analysis and comparison of the hydrogen content generated by shale with different maturity in open and closed systems, and determine the hydrogen generation capacity of shale at different maturity , to determine the hydrogen consumption capacity of shale under airtight conditions, making up for the gap in shale hydrogen generation experiments.

Description

technical field [0001] The invention belongs to the technical field of energy and chemical industry, and more specifically relates to a shale hydrogen generation experimental device, an experimental method and an analysis method. Background technique [0002] Hydrogen plays an important role in the hydrocarbon generation and maturation of organic matter, for example, accelerating the dealkylation of alkylaromatic compounds, hydrogenation with olefins to form alkanes through thermal cracking reactions, and generation of hydrocarbon gases by reducing carbon dioxide. However, under high temperature cracking of shale, hydrogen gas is an essential product, and no hydrogen gas pools have been found in most shale gas pools. [0003] At present, artificial pyrolysis technology is considered to be the only way to simulate the hydrocarbon generation process of sediments, but the research on the gas generation of shale in artificial pyrolysis experiments, and the generation of hydrogen...
