This paper proposes a review of hydrodynamics problems encountered in calalytic reactor characterized by a fixed catalyst bed and crossed by gas/liquid or liquid flows. These reactors are typical reactors of petrochemical or refinery processes. These hydrodynamic problems are specifically studied at the French Institute of Petroleum center of Solaize (IFP/Solaize). Once background of these studies presented, the different instrumentation techniques are described by emphasizing on development needs. Finally, at the end of the paper, a special attention is paid ta instrumentation and modeling needs concering gas/liquid flow across a fixed bed of solid particle.
