摘要: Abstract The application of thermal pretreatments to facilitate its anaerobic digestion has associated phenols and furans production, which are commonly identified as inhibitory compounds. Phenols extraction can be done from a liquid phase produced after the pretreatment. In present study this dephenolized (DLP) showed an increase 42% in methane yield compared raw (LP) demonstrating inhibitor character such main extracted were: 3,4-Dihydroxyphenylglycol (DHPG), Hydroxytyrosol (HT), Tyrosol (Ty), Vanillic acid (AcV), Hydroxymethylfurfural (HMF), Vanillin (V) Furfural (F).This also aimed evaluate individual effect on production these specific within mixture several ones LP. evaluation compounds over methanogenesis that only V was both rate. HMF had significantly negative yield, but improved rate instead. Ty, F, DHPG HT favoured Additionally, it observed some counteracted by positive other
