| Abstract |
In this work, the autohydrolysis of Ziziphus lotus has been used as a pretreatment that permitted the integral revalorisation of this feedstock by obtaining oligosaccharides, lignin and cellulose nanofibres. For that, firstly, the temperature of the autohydrolysis process was optimised to maximise the production of oligosaccharides, obtaining 17.8 g/L of oligosaccharides at the optimum conditions. Afterwards, the effect of the autohydrolysis pretreatment on the effectiveness of the subsequent biorefinery steps and on the characteristics of the obtained products was analysed. It was observed that the autohydrolysis pretreatment not only increased the organosolv delignification process by 42.7%, but also decreased polydispersity of the obtained lignin by 33.82%. Regarding the cellulose nanofibres, their crystallinity index increased from 74.3 to 79.2% due to the effect of the autohydrolysis treatment. Thus, the autohydrolysis pretreatment would permit the integral revalorisation of Ziziphus lotus by a biorefinery approach that could be an example of the circular economy and of a zero-waste production. |
