N.F. — 1972 — B. 80 — S. 1-20The non-isothermal degree of conversion λ and the equilibrium advancement for the process λeq are defined by the relationship λ = α∙λeq where α is the isothermal degree of conversion. The precise meaning of non-isothermal kinetics in relation to basic types of processes studied under dynamic conditions is discussed. For an invariant type of process the correct form of the kinetic equation is investigated. For the universal non-isothermal kinetic equation, a modified rato for the process is given by
dξ/dt = (dλ/dt – λ∙ф∙dlnλeq/dT)/λeq
for the temperature T, time t and the constant heating rate ф. Thus in mono-variant and permanent processes it becomes necessary to establish the λeq vs. T dependence.
dξ/dt = (dλ/dt – λ∙ф∙dlnλeq/dT)/λeq
for the temperature T, time t and the constant heating rate ф. Thus in mono-variant and permanent processes it becomes necessary to establish the λeq vs. T dependence.
