Monolithic Loop Reactor MLR

The MLR has become a subject of marketing agreement between Air Products and Chemicals Inc. and Johnson Matthey [49]. 

Boger et al. [50] analyzed the performance of MLRs with internal density-driven circulation (IMLR). They found the gas-hquid mass transfer superior and the overall mass transfer performance comparable with those for slurry reactors.

Monolithic Loop Reactor A novel MLR was developed af Air Products and Chemicals (Figure 17) (144). The reactor contains a monolithic catalyst operating under cocurrent downflow condifions. Because the residence time in the monolith is short and the heat of reaction has to be removed, the liquid is continually circulated via an external heat exchanger until the desired conversion is reached. The concept was patented for the hydrogenation of dinifrofoluene fo give toluenediamine (37).
