The products obtained were analysed to determine the yield, selectivity to monomers, chemical structure and molecular weight distribution. The char formation was low in most cases, but the proportion of heavy and light oils were variable upon the starting material used. The monoaromatics yield depends mostly on the type of lignin utilized being the non-wood biorefinery lignins less suitable for monomers production than the technical wood ones (13-8%). The monomer distribution depends on the biomass of origin and the pulping method. This technology is equally effective when directly treating a black liquor and better results are obtained if compared to the corresponding isolated lignin.Ministerio de Ciencia, Innovación y Universidades - Fondo Europeo de Desarrollo Regional (grants CTQ2016-79777-R and PID2019-105975 GB-I00)Junta de Castilla y Leon - Fondo Europeo de Desarrollo Regional (grants VA277P18 and CLU-2019-04)Elsevier2022info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://doi.org/10.1016/j.biombioe.2022.106536https://uvadoc.uva.es/handle/10324/54128reponame:UVaDOC.
