WebOne of the main problems to overcome during the scale-up of such reactors is to optimize the gas/liquid flow distribution across the reactor catalytic bed section. To accurately characterize the gas/liquid flow distribution inside a real catalytic bed, a new computed gamma-ray tomographic system has been developed to investigate two-phase flow …

WebHydrodenitrogenation (HDN) of the Aleksinac shale oil distillates was studied in a pilot trickle-bed reactor at 340–435°C, 8.0 MPa, 1–4.57 h−1 liquid hourly space velocity (LHSV) and 500 cm3 (STP) of H2/cm3 oil. The commercial Co Mo Al 2 O 3 and Ni Mo Al 2 O 3 presulfided catalysts were evaluated for the HDN of three different shale oil distillates. Webunder similar hydrodynamic conditions in trickle flow. In addition to introducing a method for the direct measurement of LS, the data presented also confirm that estimates of LS are more accurate when performed in an environment in which the hydrodynamics and fluid-solid contacting conditions are representative of the system of interest.
