Abstract:
This study was held to examine medical cotton wastes’ heating value in a set of experiments. Medical cotton waste was pre-treated in a batch reactor. The reaction occurred was the acid hydrolysis of the cotton fracture with time, temperature and concentration of dilute acid solution as pre-treatment parameters. The chosen acid was diluted sulfuric acid. Temperature (180; 200 and 220 0C), acid concentration (0.01; 0.023 and 0.035 M), and reaction time (0; 20; 40 min) were chosen as the experiment parameters. The number and the sequence of experiments were based in the design of experiments (DOE) method. The produced solid material of the pre-treatment was dried and weighted before it was put in the calorimeter. The heating value was measured. Combined severity factor (CSF) was selected as the method that defines the optimal conditions that allow medical cotton waste to produce heat.
