Abstract: | The purpose of this study is to provide a better understanding of reactors for hydroprocessing of liquid-solid mixtures, and to assist in the design and scale-up of large scale reactors from the information obtained from small scale experimental units. The paper describes a linear, isothermal, cocurrent upflow tubular reactor model with axial dispersion. The model is applied to coal liquefaction, assuming that the complex liquefaction kinetics can be represented by five lumped components-six first order reactions, and that the three phase (coal-solvent-gas) flow can be approximated by a two phase (slurry-gas)flow. |
