Pilot plant reactors offer very important advantages in testing operating conditions such as temperature, pressure, residence time, catalyst to feed ratio, instrumentation and so on. However, such units are very costly when used, for example, for catalyst and feedstock screening tests where many tests are required to find out the effect of new formulations on product yield under different operating conditions. Micro-reactors are, on the other hand, ideal equipment for such purposes as with such systems running an operation is not expensive, performing a test does not take significant time, switching from an operating condition to one another is rather quick and above all, mass of required catalyst and feedstock is small i.e. in the order of grams. Therefore, considerable time and cost are saved through running tests in the small-scale reactors.
PEARL members Dr. Said Samih, Dr. Mohammad Latifi, Dr. Sherif Farag and Prof. Jamal Chaouki reviewed some state-of-the-art micro-reactors that they have developed and commissioned at PEARL in the Journal of Chemical Engineering and Processing- Process Intensification.
