NOVELTY - The apparatus comprises container which has cooling jacket, and water or antifreeze supply line. Gas introduction pipe (13) inserted at center section of container, rotation shaft (12) inserted in main axis of pipe (13), and motor (10) for driving shaft (12) are provided. Stirring blade at lower end of pipe (13), gas containing methane introduction unit and methane hydrate ejection unit are provided.    USE - For manufacturing methane hydrate from gas containing methane e.g. natural gas.    ADVANTAGE - The gas containing methane, and water or antifreeze are reacted continuously, thereby methane hydrate is manufactured continuously with high yield.    DETAILED DESCRIPTION - The apparatus comprises cylindrical container (1) which has cooling jacket (3), and water or antifreeze supply line (5). A gas introduction pipe (13) inserted in the center section of container (1), rotation shaft (12) inserted in the main axis of pipe (13), and motor (10) for driving the rotation shaft are provided. A propeller type stirring blade (24) is provided at the lower end of rotation axis. A gas dispersion unit is provided so that the edge part of the stirring blade is surrounded at the lower end of pipe (13). An unit for introducing gas containing methane through pipe (13), and an unit for ejecting methane hydrate formed within container (1) to the exterior, are provided. An INDEPENDENT CLAIM is also included for manufacture of methane hydrate. Gas containing methane is passed through pipe (13) into container (1) at 1-4degreesC and 30-100 barometric pressure. The stirring blade is rotated at a circumferential speed of 0.5-20 m/s to attract water or antifreeze, and gas to the stirring blade. After which water or antifreeze, and gas are collided to form methane hydrate.    DESCRIPTION OF DRAWING(S) - The figure shows explanatory drawing of the methane hydrate manufacturing apparatus.
