Abstract
The wheat straw delignification condition influence in the medium “acetic acid-water-hydrogen peroxide-citric acid catalyst” to the yield and cellulose product composition was studied. It was established that the fibrous semi-finished product output and the residual lignin content are decrease with increasing temperature and delignification duration. The oxidative wheat straw delignification process was described by a first-order kinetic equation, and it was characterized by low activation energy values of 16.7 kJ mol-1. The oxidized cellulose sample’s structure was studied using IR spectroscopy.
