Artificial bacterial degradation and hydrous pyrolysis of suberin: Implications for hydrocarbon generation of suberinite

► We performed artificial bacterial degradation and hydrous pyrolysis experiments on suberin. ► The hydrocarbon evolution of suberinite was addressed based on the experimental data. ► Suberinite has a two-stage and relatively long oil generation history. ► Suberinite is a good bio-precursor for the immature and low mature coal-derived oil generation.
