WebApr 1, 2024 · at the start of a batch reactor or in the feed for a flow reactor. Illustration 2 This illustration pertains to an autocatalytic reaction and involves comparison of space times ( 1: ) required for steady-state isothermal operations of a CSTR and a PFR. The reaction A+ B š 2B occurs as per the kinetics r = kC A CB. 15 Webwhere p is in bar, T is in K, R = 1.987 cal/mol K, and ri is in mol/m3 reactor s. When simulating this, or any reactor in Chemcad, the units for the reactor may be set separately from the units for the rest of the simulation in the “more specifications” tab. The reaction units in Chemcad must be moles/reactor volume/time.
