Topics: Chemistry and Pharmacology

Notes: Abstract The homotopic method has been used to analyze the kinetic model of three-stageCO oxidation on two nonuniform surface patches conjugated byCO 2 spillover. Diagrams of steady states depending on the portion of surface patchm 1 at various temperatures and pressure ratiosP(O 2)/P(CO) have been constructed. The ratios of different type patches corresponding to the maximum overall reaction rate have been found.

Notes: Abstract The homotopic method has been used to analyze the kinetic models of CO oxidation on two surface patches conjugated by COads spillover. On each patch reaction proceeds via a three-stage mechanism but with different constants. The stability of steady-states solution has been studied. COads spillover from one patch to another changes substantially the bifurcation picture of steady states and produces islands.
