H-factor

This article is about a kraft pulping model. For the metric measuring scientific research impact, see 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.

$H=\underset{0}{\overset{t}{\int }}\exp (43.2-16115/T)dt$
