RF-ID 시스템은 트랜스폰더 응답 신호용으로, 예를 들어 5msec지속 시간의 좁은 질의 펄스를 전송한 다음, 예를 들어 1msec의 균일한 짧은 지속시간 동안 모니터링한다. 모니터링 지속시간은 가장 효율적인 충전 시스템을 형성하기 위해 최소로 유지된다. 트랜스폰더 응답 신호의 부재시에 질의기 내의 수신기가 응답 신호를 검출할 때까지 질의기가 단계적으로 질의 펄스 지속 시간을 증가시킨다. 응답 신호는 그 내부에 위치한 캐패시터에 저장된 전압으로 나타내는 질의 신호로부터 충분한 파워를 받아들였음을 가리킨다. 이 시스템은 트랜스폰더가 일련의 결합된 짧은 지속 시간의 파워 펄스를 갖는 최종 충전 전압 레벨을 성취할 수 있도록 방전 기능을 갖지 않은 트랜스폰더에 의해 지원되거나 또는 방전 기능을 갖고 있고 충분한 전압을 받아들이기에 적합한 지속 시간의 질의 펄스를 기다려야만 하는 트랜스폰더에 의해 지원될 수 있다. 선택적으로, 질의 펄스의 지속 시간을 증가시키는 대신, 질의 펄스의 진폭을 증가시켜 전송된 질의 파워량을 유사하게 증가시킬 수 있다.

An operating severity index based on the calculated reaction order is then calculated. According to one aspect, the operating severity index comprises an operating temperature of the reactor to yield the product stream with the desired sulfur content from the first liquid hydrocarbon feed. According to another aspect, the carbazoles content of a plurality of liquid hydrocarbon feeds are measured to generate a database of the measured carbazoles content. Fig 1.
