Multi-temperature-zone ortho-parahydrogen calibration system and method suitable for different catalyst activation modes

The invention discloses a multi-temperature-zone ortho-parahydrogen calibration system and method suitable for different catalyst activation modes. The multi-temperature-zone ortho-parahydrogen calibration system comprises an ortho-parahydrogen catalyst activation device and a multi-temperature-zone calibration device. The activation device comprises a vacuum pump, a constant-temperature oil bath box and an activation cavity, the activation cavity is soaked in the constant-temperature oil bath box to obtain a constant-temperature environment, an ortho-parahydrogen catalyst is placed in the activation cavity, and an upper cavity opening of the activation cavity is connected with the vacuum pump through a filter pipe; the calibration device comprises a gas chromatograph, a hydrogen generator, a calibration converter, a liquid bath pool and a driving gas cylinder, wherein the outlet of the hydrogen generator is divided into two paths, one path passes through the flow regulating valve and then is directly connect
