Black liquor is a by-product of the paper pulping operation. It is a diverse combination of organic and inorganic chemicals all of which provide chemical meaning and resources. The black liquor is concentrated at a concentration of about 60-85 of solids, and is shot into a recovery boiler with these two amounts. The black liquor is poured in the boiler in the shape of gout, which is sprinkled in the furnace atmosphere. The droplet is then dried, removed, and burned in series before coalescing with the smelt on the rim. The formulation of these processes during motions of the black liquor droplet is very complicated and, in this paper, we try, by observing the pyrolysis of dry-black liquor solids in a muffle furnace and simulating the weight loss during the despoliation period. At temperatures between 973 and 1274 K and for the period of residence between 30 and 180 s, experiments were carried out. A single reaction, which gives gaseous volatility and carbon, is used for the kinetic design of dry black liquor solids. The single reaction model suggested is smelled and by utilizing the two-dimensional non-linear regression algorithm, the best values of kinetic parameters are found activation energy and Arrhenius constant. The results show a strong consensus among forecast and test details.
