Device and Method for Determination of a Catalyst State in a Chemical Reactor

A device for determination of a catalyst state in a chemical reactor, comprising:

• a reactor comprising a reactor chamber with at least one inlet for introducing a fluid phase into the reactor chamber and at least one outlet for draining off the fluid phase,
• a sampling device for collecting a fluid sample inside the reactor chamber,
• a temperature-sensitive sensor arranged at the sampling device for detecting a temperature of a fluid phase and/or a solid phase at the site of the sampling device where the fluid sample is collected,
• wherein
• a spectroscopic detection unit arranged outside the reactor, said spectroscopic unit comprising a sample chamber for arranging a sample therein and a spectroscopic analysis device for obtaining spectroscopic data on the sample arranged in the sample chamber,
• a conduit is provided between sampling device and the sample chamber of the spectroscopic detection unit for introducing a sample taken at the sampling device into the sample chamber of the spectroscopic detection unit,
• heating and/or cooling means and a temperature control unit is provided in the spectroscopic detection unit for adjustment of a temperature of the sample chamber.
