GUTIERREZ-HERNANDEZ, JUAN PABLO; FONTALVO ALZATE, JAVIER  e  GOMEZ GARCIA, MIGUEL ÁNGEL. MAPPING THE REGION OF INSTABILITY FOR ADIABATIC PACKED BED REACTORS USING A HOMOTOPY CONTINUATION METHOD. Dyna rev.fac.nac.minas [online]. 2010, vol.77, n.163, pp.85-91. ISSN 0012-7353.

The pioneer schematic ideas of Kimura and Levenspiel (Ind. Eng. Chem. Proc. Des. Dev., 16 (1977) 145 - 148) have been developed to find numerically the region of instability for adiabatic packed bed reactors. Three different cases of special industrial interest and complexity are presented. The highly exothermic gas-phase reactions: ammonia synthesis, methanol production from syn-gas, and SO₂ oxidation. Equations were parameterized and solved according to a continuation homotopy numerical method. The results showed that concentration of inerts and total pressure influences the size of the instability region.

Palavras-chave : Instability region; adiabatic packed bed reactors; homotopy continuation method.
