“…Some considerations of the problems analysed theoretically have been applied to specific industrial problems as Dumez and Froment (1976) did to the dehydrogenation of 1-butene to butadiene with complex kinetics for both the main and deactivation reactions, Mansson and Andresen (1985) to the ammonia synthesis with kinetic equations of the type of Temkin-Pyzkev, Culfaz et al (1984) to the isomerization of pentene, and some others (Noda et al, 1975;Weekman, 1968Weekman, , 1969Nace et al, 1971;Voltz et al, 1972;Gross et al, 1974).…”
