Analytical expressions are developed for the evaluation of global heat transfer coefficients for the heterogeneous one-dimensional (Het l-D)-flxed bed reactor model. These expressions are evaluated from the associated two-dimensional (Het 2-D) model applied at the hot-spot conditions ocurring for exothermic reactions, and include the effect caused by the dependence of heat generation with temperature. The comparison between the Het 1-D and Het 2-D models covering an important range of typical industrial operating conditions, shows that very precise estimates can be achieved with the former, provided that conditions of parametric sensitivity does not occur. For instance, maximum differences in average gas temperature are less than 6°C |
