In the design of hydrotreating reactors with a fixed bed of granular catalyst, it is assumed that the flows of feed and hydrogen-rich gas (HRG) are uniformly distributed across the section of the vessel. However, operating data obtained on such reactors show that the reactant distribution may be nonuniform under certain conditions. The aerodynamic parameters of the catalyst grains influence the chemical reaction rate and the effective service life of the catalyst, as well as its selectivity, activity, and grain condition (coking, sintering). One of the manifestations of low nonuniformity is higher velocities at the walls. This phenomenon is governed by parameters of the granular medium.
