WebHence, product distribution is fixed by k2/k1 alone and is unaffected by type of reactor used. We also may control product distribution by varying k2/k1. This can be done in two ways: 1. By changing the temperature level of operation. If the activation energies of the two reactions are different, k2/k1can be made to vary. 2. By using a catalyst. WebCSTRs in Parallel. We now consider the case in which equal-sized reactors are placed in parallel rather than in series, and the feed is distributed equally among each of the reactors (Figure 4-5). A balance on any reactor, say i, gives… [Pg.87] CSTRs in parallel.
