It is proposed to put a PBR containing the same catalyst weight in series with the CSTR. The pressure drop parameter for the PBR, a, given by Equation (5-29) is a 0.018 kg The particle size is 0.2 mm, the bed porosity is 40%, and the viscosity is the same as that of air at 200°C.
WebMay 22, 2010 · The current study describes the results on the selective hydrogenation of the 2-butyne-1,4-diol to 1,4-butanediol over Raney® nickel catalysts both in batch and in CSTR mode. The detailed kinetic analysis of the reaction in batch mode revealed the existence of three characteristic regions.

Web6.1 Continuous Stirred Tank Reactor. Continuous stirred tank reactor (CSTR) is the most generally employed bioreactor for biohydrogen production in continuous mode because of its simplicity in configuration, easy functioning, efficient uniform stirring, and proper maintenance of temperature and pH (Fig. 10.2A ). WebCSTR Model. The adiabatic continuous stirred tank reactor (CSTR) is a common chemical system in the process industry, and it is described extensively in [1]. A single first-order exothermic and irreversible reaction, A → B, takes place in the vessel, which is assumed to be always perfectly mixed. The inlet stream of reagent A enters the tank ...
