Abstract BTX (benzene, toluene, and xylene) was gained from anisole by gas-phase hydrodeoxygenation (HDO) at ambient pressure with zeolite catalysts. The role of supports such as HBeta, ZSM-5, HY, and γ-Al 2 O 3 was investigated. The effect of temperature and 1/WHSV on the product distribution was also evaluated. The results show that the content of BTX with Fe/Ni/HBeta catalysts, peaked at 24.87%. Fe/Ni/ZSM-5 promoted transalkylation and Fe/Ni/γ-Al 2 O 3 exhibited the lowest anisole conversion of 30%. N 2 -adsorption, XRD and NH 3 -TPD analysis of Fe/Ni/supports suggested that BET surface, pore size, amount and intensity of acid sites significantly influenced products distribution. BTX and phenol were mainly products, indicating that hydrogenolysis focused on C aromatic -OCH 3 and O-CH 3 skeletons, not on π-bone in the anisole ring at ambient pressure. The products such as toluene, xylene, and other multi-methylated aromatics were from transalkylation of benzene and phenol. Fe/Ni supported catalysts were not only beneficial for HDO to remove oxygen but also for transalkylation, mining carbon loss.

使用沸石催化剂在环境压力下通过加氢脱氧和烷基转移从苯甲醚中提取 BTX

摘要 以苯甲醚为原料，在沸石催化剂的作用下，在常压下通过气相加氢脱氧(HDO) 制得BTX（苯、甲苯和二甲苯）。研究了HBeta、ZSM-5、HY和γ-Al 2 O 3 等载体的作用。还评估了温度和 1/WHSV 对产品分布的影响。结果表明，BTX与Fe/Ni/HBeta催化剂的含量峰值为24.87%。Fe/Ni/ZSM-5 促进了烷基转移，Fe/Ni/γ-Al 2 O 3 表现出最低的苯甲醚转化率，为 30%。Fe/Ni/载体的N 2 -吸附、XRD和NH 3 -TPD分析表明BET表面、孔径、酸性位点的数量和强度显着影响产物分布。BTX和苯酚是主要产物，表明氢解主要集中在C芳族-OCH 3 和O-CH 3 骨架上，不在环境压力下苯甲醚环中的 π 骨上。甲苯、二甲苯等多甲基芳烃产物是苯和苯酚的烷基转移反应。Fe/Ni负载的催化剂不仅有利于HDO脱氧，而且有利于烷基转移、采矿碳损失。
