Tubular Reactor with Bypassing

A first order reaction, A => 2B, is carried out in a battery of two equal CSTRs followed by a tubular flow reactor with a volume Vr3 = 20 cuft. The process is adiabatic. Input consists of 20 lbmols of A dissolved in 100 cuft of solvent and is at 100 F. As shown on the sketch, 25% of the fresh feed bypasses the first CSTR. Specific volumes are independent of temperature and are additive. Heat of reaction at 560 R is AHr = -70,000 Btu/lbmol and specific rate is... 

In order to examine the elfect of flow pattern in a reactor, which is a crucially important design factor of an LCVD reactor, it is necessary to examine the profile of deposition in a simple reactor first. A tubular reactor with an external radio frequency power coupling is ideally suited to the study of the distribution of polymer deposition. In such a reactor, 100% of the monomer passes through the luminous gas phase in the reactor, and the situation is very close to the case in which no bypass of monomer occurs. The experimental setup used for... 

The catalyst powder (0.8 g) was placed in a tubular quartz reactor. The composition of the gas flow was obtained by mixing the different components (CO, O2, NO, CsHg) diluted in N2 with the use of gas flowmeters. For all experiments the ratio (oxydant species/reductive species) was taken equal to 1. Before each reaction, the reactor is bypassed in such a way as to know precisely the composition of the gas flow before reaction.
