Abstract

A TCF bleaching sequence including an oxygen delignification stage for the ALCELL(R) process, namely, OQE(op)(PaP), was developed. It was found that a fully bleached pulp with brightness of higher than 88% ISOcan be produced with total hydrogen peroxide charge of 1.7% and peracetic acid charge of 0.44% (as H2O2) The strength properties of the above TCF-bleached pulp are comparable to those of the same furnish ALCELL(R) pulp bleached by the standard ODED sequence.
