Due to the detrimental effects induced by transition metals on oxygen delignification, it is necessary to explore effective cellulose protector for improving the oxygen delignification efficiency. In this work, chitosan/tripolyphosphate microspheres (C/TPP) with different size were prepared and introduced for alleviating the transition metal ions effects on cellulose degradation. The results showed...
Magnesium salt is a known cellulose protector during the oxygen delignification process and it has been widely used in commercial practice, in particular, for feedstocks with a low magnesium presence. Minimizing the negative impact of transition metals by magnesium is one of the main mechanisms. A key parameter affecting the magnesium salt performance for this purpose is its particle size. In this...
