The distribution of biomass pyrolysis products under high pressure have rarely been reported. In this study, the effect of pressure on the product distribution of pine sawdust (PS) pyrolysis was studied. The synergistic effect of the side wall rubber (SWR) and PS was confirmed under pressurized conditions. Calcined bottom ash (CBA) and SWR char (SWRC) were used to enhance the quality of the pressurized co-pyrolysis products. The PS and SWR pyrolysis chars obtained under high pressure conditions exhibited serious melting and cross-linking problem. The CO content decreased to 19.96 vol% in co-pyrolysis gas with the CBA/SWRC catalyst. The water content decreased by 85.71% after the SWRC catalyst in the pressurized co-pyrolysis process. Compared with the concentration of benzene in PS and SWR oil, the concentration of benzene in SWR/PS oil without catalysts increased by 9.57 times and 0.25 times, respectively.
高压下生物质热解产物的分布鲜有报道。本研究考察了压力对松木屑（PS）热解产物分布的影响。在加压条件下，确认了侧壁橡胶（SWR）和 PS 的协同作用。煅烧底灰（CBA）和 SWR 炭（SWRC）被用于提高加压共热解产物的质量。在高压条件下获得的 PS 和 SWR 热解炭严重熔化和交联问题。在共热解气体中加入 CBA/SWRC 催化剂后，CO 含量降低到 19.96 vol%。在加压共热解过程中使用 SWRC 催化剂后，水含量降低了 85.71%。与 PS 和 SWR 油中苯的浓度相比，没有催化剂的 SWR/PS 油中苯的浓度分别增加了 9.57 倍和 0.25 倍。
