Estimating pure diffusion contributions in alkaline pulping processes

摘要: A model that predicts isothermal alkali diffusion and reaction with acetyl groups in moist wood chips was derived approximated. System parameters were estimated from unsteady-state ex- perimental data. Simulation results reinforce the idea effect is not fully exploited pulping processes. Traditionally, digestion con- ducted at high temperature, where delignification kinetics enhanced predominant. This approach being reviewed by modern industry since energy environmental savings associated low temperature operation might compensate for high-yield productivity. The concentration of center chip a measure completeness deacetylation, which translates into aptitude final prod- uct purposes. pre- dicted here solution to pair coupled ODE's. Since alternatives combining both high-temperature processes are studied, this paper provide basic data optimiza- tion analysis.
