In addition, the embodiment of the present invention also provides an online carbon determination evaluation method for a catalyst in a moving bed device, which can monitor the state of the carbon deposition amount of the catalyst quickly and in real time.

Description

technical field [0001] The invention relates to the technical field of petrochemical engineering development, in particular to an online carbon determination system for a catalyst in a moving bed device, an online carbon determination evaluation method thereof, and a moving bed device. Background technique [0002] The moving bed reactor is a reactor used to realize the gas-solid phase reaction process or liquid-solid phase reaction process. It is equipped with a catalyst circulation and regeneration system. The catalyst circulates between the reactor and the regenerator. After the reaction, the carbon-containing The catalyst is continuously regenerated in the regenerator and then sent back to the reactor for reaction. The catalyst in the moving bed reactor can be continuously regenerated, so the activity of the catalyst can be fully maintained and the severity of the reaction can be increased. Continuous regeneration moving bed is widely used in continuous reforming, movin...

Problems solved by technology

[0003] The establishment of an online monitoring and analysis system for various process materials in the refining and chemical process is an important part of building a smart factory. For the gas-liquid raw materials and products in the refining process, real-time online detection can be used to complete the monitoring of their physical properties and quality. The solid catalyst used in the refinery lacks an on-line detection method. There are problems such as the need to manually sample and analyze the catalyst regularly, the degree of automation and efficiency is low, and the analysis of the catalyst is not synchronized with the production. As a result, it is impossible to monitor its performance in all aspects in real time.
