Abstract: The present invention provides a method for preparing gas hydrates by reacting a plurality of guest gases with water, wherein a first guest gas has a higher water solubility than that of a second guest gas, and the pressure of the gas hydrate formation condition of the second guest gas is lower than the pressure of the gas hydrate formation condition of the first guest gas.While the traditional gas hydrate production method, wherein a single guest gas is reacted with water, is unsatisfactory in terms of cost effectiveness and productivity, the present invention provides improved production yield of gas hydrates and enables an easy production of gas hydrates at lower pressure.

Abstract: The present invention relates to an apparatus comprising a reactor body to which gas and water are supplied to create a gas hydrate; an upper cover which is engaged to an upper portion of the reactor body, a scraper mounted rotationally within the reactor body, and a motor for providing a driving force to the scraper. It is possible to remove gas hydrate particles attached to at least one of an inner surface of the reactor body and an inner surface of the upper cover, by a rotary driving of the scraper. According to the invention, it is possible to prevent a material hindering a heat transfer by attaching on a wall surface of the reactor, through a process of scraping out gas hydrate particles, when the scraper which is rotationally driven about a center axis of the reactor is close to the inner surface of the reactor.

Abstract translation: 本发明提供了一种通过使多种客体气体与水反应来制备气体水合物的方法，其中第一客体气体具有比第二客体气体更高的水溶性，并且第二客体气体的气体水合物形成条件的压力 客体气体低于第一客体气体的气体水合物形成条件的压力。 尽管其中单一客体气体与水反应的传统气体水合物生产方法在成本效益和生产率方面是不能令人满意的，但是本发明提供了气体水合物的提高的生产产率，并且能够在较低压力下容易地生产气体水合物。
