文摘

Wastes from brewerys, industrial coffee roasting, and fiberboard furniture production were investigated.Thermogravimetric experiments were carried out with different types of temperature programs. Three modelswere proposed describing equally well the behavior of the samples. One of the models consisted of threepartial reactions with distributed activation energies (DAEM). In this case 12 parameters were sufficient todescribe the behavior of a sample in the entire range of observations. The other two models were mathematicallysimpler but contained higher numbers of adjustable parameters. The reliability of the models was tested inthree ways: (i) the models provided good fit for all experiments; (ii) the evaluation of a narrower subset ofthe experiments resulted in approximately the same parameters as the evaluation of the whole series ofexperiments; and (iii) the models allowed accurate extrapolations to higher heating rates.
