“…However, to simplify the calculation, the concentration of each component in the kinetics equations was used like the works of Oost et al [5]. The reason is that the activity coefficient of methanol is different from 1, whereas the others (TAME, IA) are relatively close to 1 [3,11].…”

Synthesis of tert-amyl methyl ether (TAME) from methanol (MeOH) and tert-amyl alcohol (TAA) in the liquid phase was studied by using an ion exchange resin, Amberlyst15 (A15) in the H ϩ form. Experiments were carried out in a stirred batch reactor under atmospheric pressure. The effects of catalyst size, agitation speed, temperatures, feed ratio and water on the reaction rate were investigated. Both of intraparticle and external diffusion effects could be neglected in this system. The dehydration of TAA could be decreased by increasing the ratio of MeOH/TAA and the reaction rates were greatly inhibited by water.A kinetic model which considered the inhibition of water was proposed. The experimental results agreed well with the model.

“…[1] Moreover, the parameter range turns out to be very small. In ex- periments on the TAME system with a smaller pressure (p = 3 bar), Bravo et al [2] observed phenomena that may be due to the occurrence of multiple steady states. At a pressure of p = 2 bar large areas with multiple steady states exist for high reflux ratios.…”

“…For example, various theoretical studies predict multiple steady states for the MTBE process (see [1] and references therein). In addition, experiments in [2] suggest the existence of multiple steady states for the TAME process. To our knowledge rigid experimental evidence like those existing for reactors (see [3] and references therein) and distillation columns (see [4] and references therein) has not been reported yet for reactive distillation processes.…”

“…To achieve high conversion of olefins, in most of the processes, a reactive distillation column is incorporated in addition to a standard liquid phase fixed bed reactor. [2] This concept is common for the ETHERMAX process (Hüls/UOP), the CDMTBE and CDTAME process (CDTECH), and the CATACOL process (Institut Francais du Petrole). For the reliable design and the successful operation of reactive distillation columns, one needs a deep understanding of the physicochemical interactions of the two unit operations, reaction and distillation, in a single apparatus.…”

For various reaction systems the integration of the reaction and separation in one unit is an interesting alternative to sequential operation in reactors and distillation columns. This applies, for instance, to equilibrium reactions, such as the production of methyl tertiary‐butyl ether (MTBE) and tertiary‐amyl methyl ether (TAME), allowing higher conversions in a reactive distillation column.
