Kinetic Study of NSSC Black Liquor Combustion Using Different Kinetic Models
Abstract
Non-isothermal thermogravimetric analysis experiments were carried out to investigate combustion characteristics of neutral sulfite semi-chemical pulp black liquor solids at a temperature range of room temperature to 800°C with the heating rates of 10, 20, 30, and 50°C · min−1. The results show that there are three temperature ranges, namely volatile matter separating process (170–370°C), volatile matter burning process (370–550°C), and fixed carbon burning and alkali metal salts reacting process (550–800°C), in which the black liquor quickly loses weight. The kinetic parameters were determined for the three reaction regions by using the Kissinger method and the Ozawa method. The activation energies were higher by choosing the Kissinger method over the Ozawa method. Kinetic parameters of neutral sulfite semi-chemical pulp black liquor can supply the theory bases for establishing thermal combustion model.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
