摘要:

The subject of sintering (sometimes termed coarsening) has received considerable attention since the late 1960s, and a review [1] appeared in this journal in 1975. Significant progress has been made since then, in particular, with regard to the mechanisms and kinetics of sintering and measurement techniques. With these advances it is now possible to utilize the understanding gained for the design of reactors undergoing catalyst sintering. In fact, a few attempts have already been made.

摘要:

The opinion that performance of continuous catalytic processes under invariable conditions is highly efficient has gained great popularity, especially among chemical engineers. However, very often the optimal conditions of the process can be achieved with the so-called unsteady-state operation. The steady-state condition thus appears to be a particular case of the variety of unsteady-state conditions which can be obtained, e.g., by changing the reaction conditions. Unsteady-state operation opens up wide possibilities to form the profiles of the catalyst states, concentrations, and temperatures in reactors, thus providing more favorable conditions for the process performance.

摘要:

It has been estimated that approximately 60% of all commercial chemicals are now obtained using processes involving heterogeneous catalysis. In fact, over 90% of all new large-scale plants employ heterogeneous catalysts. This can be seen very clearly in Table 1, which lists the top 50 chemicals for the year 1980 [1].
