【００２２】
実施例２
図２は、本発明の第２実施例を示し、耐圧容器および反応容器で構成される高温高圧容器の耐圧容器の天板を貫通して該容器内に先端部が位置するように設けた導波管または同軸線路の挿入端に第１の窓（窓１）を設け、導波管または同軸線路の他方の途中に第２の窓（窓２）を設け、耐圧容器内と導波管内を等圧にし、マイクロ波発信器により発振したマイクロ波を導波管または同軸線路を介してマイクロ波透過性物質（石英）でできている反応容器内の被加熱物に照射するように構成してある。
したがって、高温高圧条件の反応では、耐圧容器の圧力と第１の窓と第２の窓の間の圧力が等しくなるように第１の窓と第２の窓の間の圧力を制御すると、第１の窓の前後の圧力は等しくなるので、第１の窓の構造としては主に耐熱・耐腐食という観点からのみその構造を考慮すれば良く薄いシート構造を適用することが可能となり、また、第２の窓は高温高圧の耐圧容器の外側に設置されるため第２の窓の構造としては主に耐圧という観点からのみその構造を選択することができる。

In that case, a hollow waveguide or coaxial line is introduced into the pressure vessel, and its opening is close to the object to be heated (liquid or slurry) in the reaction container, so that an arbitrary position of the object to be heated can be efficiently It can be heated by microwaves, and only the catalyst part can be selectively heated in the catalytic reaction.
The opening is close to the object to be heated in the reaction vessel, and the vicinity of the opening can be locally heated by selecting an appropriate frequency in consideration of the penetration depth of the microwave.

A second window is provided in the middle of the line so that the pressure inside the pressure vessel and the inside of the waveguide (in the first window and the second window) are equal, and the microwave oscillated by the microwave transmitter is waveguided or coaxially. An object to be heated in a reaction vessel made of a microwave permeable substance is irradiated via a line.
Therefore, it is possible to continuously heat the liquid flowing in the pipe line corresponding to the reaction vessel, and additionally, a process such as a cooling device or a solution introduction can be taken in, and the thermometer T in the flow path. The temperature of the object to be heated can be maintained at a set value by monitoring the temperature by controlling the microwave output.

According to the present invention, it is possible to provide a high-temperature and high-pressure vessel having a chemical reaction promoting microwave supply device in which restrictions on windows in the high-temperature and high-pressure vessel are relaxed. Further, it is possible to provide a high-temperature and high-pressure vessel having a chemical reaction promoting microwave supply device that can form a high-temperature and high-pressure state locally and promote the reaction by forming such a local reaction field.
