H-factor

See also: h-index

H-factor is a kinetic model for the rate of delignification in kraft pulping. It is a single variable model combining temperature (T) and time (t) and assuming that the delignification is one single reaction.[1]

${\displaystyle H=\int _{0}^{t}\exp \left(43.2-16115/T\right)\,dt\,}$
