The transparent reactor is a quartz cylinder enclosed in a joule effect heated stainless steel tube. A methodology to determine how to focus the microscope for liquid and solid phase characterization is presented. The setup has been validated by performing diesel hydrodesulphurisation on a CoMo/Alumina extrudate catalyst with a conversion very close to expected values along with the acquisition of Raman spectra of the solid catalyst showing an evolution of the catalyst phase during sulfidation. %G English %2 https://ifp.hal.science/hal-02061906/document %2 https://ifp.hal.science/hal-02061906/file/High%20Pressure%20High%20Temperature%20Transparent.pdf %L hal-02061906 %U https://ifp.hal.science/hal-02061906 %~ SDE %~ IFP %~ GIP-BE
