Abstract

The reductive catalytic fractionation of agricultural waste– buckwheat husks, sunflower husks, and flax shivesusing a NiRu/C bimetallic catalyst was studied. Based on the following parameters: maximum yield of monomeric phenols (18.6 % based on lignin), individual substance (guaiacyl propanol, 13 % based on lignin), cellulose (27 % based on initial content), and degree of delignification (77 %), flax shives are the most suitable substances among the studied species for current research and industrial applications. Another advantage of flax shives is the high content of guaiacyl propanol in the monophenols obtained (two- thirds). This dominance is due to the isolation and purification of guaiacyl propanol as an individual compound in the process product – a byproduct of the agricultural waste recycling process
