气体水合物快速成核生长强化方法研究进展
Research Progress on Enhanced Methods for Rapid Nucleation and Growth of Gas Hydrates
摘要
Abstract
Under the current energy structure transformation and the"Dual Carbon"strategy in our country,gas hy-drate technology holds significant potential for application in the field of carbon capture and storage.The stochastic nature of hydrate nucleation results in long induction periods and slow growth kinetics,while conventional mechani-cal intensification methods cannot satisfy the requirements for large-scale industrial application.To address this problem,researchers have proposed a series of new methods for strengthening the rapid nucleation and growth of gas hydrates.Physical strengthening methods can continuously renew the gas-liquid interface state by applying external disturbances,thereby enhancing the nucleation of hydrates;chemical additive strengthening methods can alter the properties of the solution,reducing the randomness of hydrate nucleation;material strengthening method primarily leverages the large specific surface area and good thermal conductivity of the materials themselves to promote hy-drate nucleation;and the metal corrosion enhancement method facilitates the instantaneous nucleation of hydrates by providing abundant heterogeneous nucleation sites,which result from the synergistic effect of the solid-liquid-gas triphase interface and the high density of hydrogen micro-bubbles formed during the corrosion process.关键词
