✦ Synopsis

A simulation of the product distribution obtained from catalytic hydrogenation of a brown coal from the GDR is attempted on the basis of a reaction kinetic model. The main emphasis of the modelling was on the inclusion of a non-isothermal reaction range between an initial temperature of 250°C and the hydrogenation temperature. The experimental basis was provided by hydrogenation trials in 2UOml shaking autoclaves under a hydrogen atmosphere using red mud as catalyst. The calculated model curves are compared with experimental data. The results are presented in the form of three-dimensional charts.
