Time course of reaction

To examine the catalyst deterioration under the present superheated liquid-film conditions, a long-term tetralin dehydrogenation over the carbon-supported platinum catalyst (Pt/C) was carried out under the superheated liquid-film conditions (heating temperature 240°C) at the amount ratio of 1.1 g/0.5 mL/min [13]. Figure 13.21 shows the time courses of reaction rate and conversion in the tetralin dehydrogenation. High conversion (around 50%) was maintained for longer than 5 h.

Due to die difficulties of iterating differential reactors, users are mcouraged to operate in the more user-fiiendly r ime of integral reactos, i ose design and qiera-ti(Mi are easio-. This shifts our focus from the ea to-interpret initial rate data, available fr< n differraitial reactors, to the rapid and efficient gathering of time-course-of-reaction data using int ral reacten. Data of this kind can then be used to produce believable...

The detail in the information obtained about mechanisms will depend on what sort of measurements can be made. It is always helpful if changes of several states can be followed. This again is aided by the steady improvement and diversification of the signals used to follow the time course of reactions. Sensible use of kinetic analysis can help in the design of further experiments in the search for and identification of intermediate steps...
