Branqueamento de polpa celulósica kraft de eucalipto com peróxido ácido ativado por molibdênio Kraft pulp bleaching with molybdenum activated acid peroxide (P Mo stage)

<abstract language="eng">Optimum conditions to run the P Mo stage for bleaching eucalyptus kraft pulp were 90 ºC, pH 3.5, 2 h, 0.1 kg/t Mo and 5 kg/t H2O2. The P Mo stage efficiency increased with decreasing pH (1.5-5.5) and increasing temperature (75-90 ºC), time (2-4 h), and hydrog...
