Modelling a hydroconversion reactor based on a computational fluid dynamics approach

This paper deals with the modelling of a hydroconversion reactor, operating in a slurry bubble column mode, for the upgrade of distillation residues to Lighter products. The model is based on the mass and momentum balance time-averaged equations, considering the radial dispersion of components. Simulations are carried out in two steps: first fluid dynamic variables (velocities, hold-ups and pressure drop) are obtained and then the oil cracking conversion is determined showing the distribution of products and the concentration profiles in the reactor. Results show good agreement with physical behaviour.
