Parece que o reator não tem tradução exata em português, por isso a minha sugestão é de acordo com a definição do reator:
"film-shear reactor is illustrated in FIG. 2. The reactor features a rotor plate that can be adjusted to within hundreds of microns from a stator plate. This close proximity, combined with rapid rotation of the rotor, subjects the HC and the extraction solvent between the two plates to high shear rates. The design of the reaction zone causes the non-miscible HC and extraction solvent streams to encounter each other under conditions of high shear. Contact of the fluids within this narrow gap results in intense mixing and intimate contact of the two phases. A heat exchanger allows control of the temperature in the reaction zone. Furthermore, unlike the specially designed facilities that are required to accommodate the high temperatures and pressures required for HDS, the small size of the film-shear reactor (10 in. high) in one embodiment makes this technology ideal for portable applications."
