Experimental study on the static formation characteristics of carbon dioxide hydrate

Abstract

As the most important greenhouse gas affecting the ecological environment, carbon dioxide is converted into oil, and the large-scale use of primary energy such as coal is increasing. The use of hydrate technology to store carbon dioxide on the seabed is an effective way to reduce the carbon dioxide content in the atmosphere. A set of hydrate formation experiment equipment was developed in this paper to simulate the environment of seabed porous media sediments, and CO2 hydrate was used as the research object to conduct experimental research on hydrate formation characteristics, and to analyze the influence of initial pressure and reaction temperature on the hydrate reaction process. Through a large number of experimental studies, this article mainly obtains the following results: (1) The process of CO2 hydrate formation is an exothermic reaction. As the initial pressure of the system increases or the reaction temperature decreases, the more heat will be released when hydrate is formed in the kettle, and the peak temperature will naturally be higher. (2) The lower the reaction temperature or the increase in initial pressure, the greater the amount of CO2 hydrate formation.
