MODELLING OF SUBCRITICAL AUTOHYDROLYSIS PROCESS OF WHEAT STRAW

https://doi.org/10.21285/2227-2925-2017-7-4-120-125

Abstract

Modelling of the process of subcritical autohydrolysis of wheat straw for optimising the conditions for the maximum yield of sugars was carried out. As a result of the correlation analysis, it is established that the processing time has the most pronounced effect on the yield of sugars. A mathematical model of the process is found and optimal conditions are established: temperature - 200 ° C, pressure - 30 MPa and duration - 60 minutes.
