Abstract High density polyethylene (HDPE) was applied as a co-feeding feedstock on the catalytic pyrolysis (CP) of yellow poplar (YP) over mesoporous catalysts, Al-MCM-48 s(SiO2/Al2O3: 23, 80) and Al-MSU-F(SiO2/Al2O3: 82). Compared to the non-catalytic thermogravimetic (TG) analysis of HDPE, catalytic TG analysis of HDPE had much lower decomposition temperatures, 407 °C over Al-MCM-48(23), 432 °C over Al-MCM-48(80) and 446 °C over Al-MSU-F(82). On the other hand, the decomposition temperatures of HDPE increased up to 460 °C over Al-MCM-48(23), 482 °C over Al-MCM-48(80), and 492 °C over Al-MSU-F(82) by applying the mixture of HDPE and YP as a feedstock on the catalytic TG analysis. The experimental yields of aromatic hydrocarbons obtained from the catalytic co-pyrolysis (CCP) of YP and HDPE over mesoporous catalysts were much higher than their theoretical yields. Among mesoporous catalysts, Al-MCM-48(23) produced the larger amount of aromatic hydrocarbons (2.89%) on the CCP of HDPE and YP than those (2.34–2.48%) over Al-MCM-48(80) and Al-MSU-F(82) and also provided the highest synergistic effect on the formation of aromatic hydrocarbons. The higher synergistic effect over Al-MCM-48(20) was achieved by applying the higher YP/HDPE ratio in the feedstock (3/1), higher catalyst/sample ratio (4/1), and higher reaction temperature (600 °C).

使用高密度聚乙烯 (HDPE) 作为共进料在 Al-MCM-48 和 Al-MSU-F 上催化热解黄杨

摘要 以高密度聚乙烯 (HDPE) 作为共进料,在介孔催化剂 Al-MCM-48 s(SiO2/Al2O3: 23, 80) 和 Al- MSU-F(SiO2/Al2O3:82)。与 HDPE 的非催化热重 (TG) 分析相比,HDPE 的催化热重分析具有低得多的分解温度,Al-MCM-48(23) 为 407 °C,Al-MCM-48(80) 为 432 °C和 446 °C 超过 Al-MSU-F(82)。另一方面,HDPE 的分解温度在 Al-MCM-48(23) 上升高至 460 °C,在 Al-MCM-48(80) 上升高至 482 °C,在 Al-MSU-F 上升高至 492 °C( 82) 通过应用 HDPE 和 YP 的混合物作为催化 TG 分析的原料。YP 和 HDPE 在介孔催化剂上催化共热解 (CCP) 获得的芳烃的实验产率远高于其理论产率。在介孔催化剂中,Al-MCM-48(23) 在 HDPE 和 YP 的 CCP 上产生了更多的芳烃 (2.89%) 比 Al-MCM-48(80) 和 Al- MSU-F(82) 并且还对芳烃的形成提供了最高的协同作用。通过在原料中应用更高的 YP/HDPE 比 (3/1)、更高的催化剂/样品比 (4/1) 和更高的反应温度 (600 ° C)。48%) 超过 Al-MCM-48(80) 和 Al-MSU-F(82) 并且还提供了对芳烃形成的最高协同效应。通过在原料中应用更高的 YP/HDPE 比 (3/1)、更高的催化剂/样品比 (4/1) 和更高的反应温度 (600 ° C)。48%) 超过 Al-MCM-48(80) 和 Al-MSU-F(82) 并且还提供了对芳烃形成的最高协同效应。通过在原料中应用更高的 YP/HDPE 比 (3/1)、更高的催化剂/样品比 (4/1) 和更高的反应温度 (600 ° C)。
