It is necessary to pass through a deoxygenation reactor to reduce the oxygen content. When all deoxygenation reactors are operated, if the temperature is not properly controlled, incomplete reaction of the catalyst occurs, resulting in failure to reduce the desired oxygen content. The temperature inside must be strictly controlled. The previous deoxygenation reactor generally adopts a single-point thermocouple to test the temperature of a temperature field, and the temperature of only one point can be measured. However, the temperature of different positions of the whole reactor is different, the temperature can be measured only by matching a plurality of common thermocouples, and the temperature measurement error is often very large.
