WebThe continuous stirred-tank reactor ( CSTR ), also known as vat- or backmix reactor, mixed flow reactor ( MFR ), or a continuous-flow stirred-tank reactor ( CFSTR ), is a common model for a chemical reactor in chemical engineering and environmental engineering. A CSTR often refers to a model used to estimate the key unit operation … WebOn another hand, the efficiency between CSTR and PFR have been compared in terms of the hydrogen production from thermal decomposition of water and isothermal-type reactor with membrane. It was found that hydrogen yield of PFR-type membrane reactor is about 1.5 times larger than that of CSTR-type membrane reactor (Ohya, Yatabe et al. 2002).
