Kinetic Analysis of the Gas-Phase Reactions of Methyl Vinyl Ketone with the OH Radical in the Presence of NOx

Abstract: Um mecanismo explícito para a reação do metil-vinil-cetona com radicais OH, numa mistura NOx-ar, foi simulado resolvendo as equações diferenciais ordinárias usando o método Runge-Kutta-4-semi-implícito. Os resultados simulados são consistentes com os dados experimentais publicados e o modelo explica as principais vias de reação para a oxidação do MVK com radicais OH na presença de NOx-ar. Usando uma análise dos autovetores e autovalores dos coeficientes de sensibilidade, para todas as espécies químicas envolvi… Show more

“…Thus, a small deviation in k 20 or j 36 should largely affect the simulation results. The same conclusions were obtained in the simulation of methyl-tert-butyl ether (MTBE) 43 and methyl vinyl ketone (MVK) 44 Principal components ψ 1 to ψ 31 contain steps (3)- (10), (12)- (16), (18), (20)- (26), (28)- (36), (39)- (43), (46)- (47) and (50), forming the "basic" part of mechanism. According to ψ 1 , the most influential reaction sequence is formed by (36), (20), (4) and (5).…”
