石油的大量消耗和环境的日益恶化引发了人们对可持续化学的关注和发展。生物质能源是地球上唯一可再生的碳源，被认为是替代目前短期内无法再生的化石燃料的潜在能源。生物质热解挥发分在ZSM-5上催化生成芳烃是一种有前途的生物质增值化利用方式，通过调节ZSM-5分子筛孔道结构和表面活性位点来提高轻质芳烃的产率和抑制积炭的生成。采用十六烷基三甲基溴化铵(CTAB)为模板剂，使用晶种法在合成过程中添加了金属Zn合成多级孔Zn/ZSM-5分子筛，阐述了合成过程中金属Zn与CTAB的作用对ZSM-5晶化过程的影响，并将该催化剂应用于纤维素热解挥发分催化重整制备轻质芳烃的研究中。并使用XRD、SEM、BET、NH₃-TPD和XPS等手段对催化剂进行表征，从而得到催化剂的物化结构。结果表明，适量CTAB的加入增大了分子筛的比表面积，显著增加了介孔，促进了反应物与产物的传质，抑制了反应中积炭的生成。并且CTAB的存在能够调控金属Zn的存在形态，加强了金属Zn与分子筛骨架的相互作用，形成更多的Zn-OH⁺活性位点，使催化剂拥有较强的脱氧能力和氢转移能力，促进了碳氢化合物的芳构化，金属Zn的加入也弥补了酸量的降低。ZnZ5-1(合成初始物料中CTAB/SiO₂摩尔比为1)具有适宜的介孔(3～10 nm)和适当的酸量，表现出较好的催化性能，轻质芳烃产率最高达166.7 mg/g。在合成过程中使用介孔模板剂的同时引入金属活性位点，通过2者协同作用调控催化剂特性，为提高生物质挥发分催化重整制轻质芳烃产率提供了思路。

The massive consumption of petroleum and the increasingly deteriorating environment has triggered the attention and development of sustainable chemistry. The catalytic generation of aromatic hydrocarbons from biomass pyrolysis over ZSM-5 is a promising method for biomass value-added utilization. In this study, the yield of light aromatic hydrocarbons was improved and the generation of carbon deposition was inhibited by adjusting the pore structure and surface active site of ZSM-5 molecular sieve. The hierarchical Zn/ZSM-5 was synthesized by using cetyltrimethyl ammonium bromide (CTAB) as template by crystal seed method. The effect of the interaction of metal Zn and CTAB on the crystallization of ZSM-5 was described. The catalyst was used to prepare light aromatic hydrocarbons by the catalytic reforming of cellulose volatiles. The catalysts were also characterized using XRD, SEM, BET, NH₃-TPD and XPS to obtain the physical and chemical structures of the catalysts. The results showed that the addition of appropriate CTAB increased the specific surface area of the zeolite, significantly increased the mesoporous, and promoted the mass transfer of the reactants and products. Moreover, the presence of CTAB can regulate the presence of metal Zn, strengthen the interaction between metal Zn and zeolite skeleton, and form more Zn-OH⁺ active sites, so that the catalyst has a strong deoxidation ability and hydrogen transfer ability, and promote the aromatization of hydrocarbons. The ZnZ5-1 (The molar ratio of CTAB/SiO₂ in the initial material synthesized is:has suitable mesoporous (3−10 nm) and appropriate acid content, and the highest yield of light aromatic hydrocarbons is 1) 166.7 mg/g. The ZnZ5-1 has a good catalytic performance in the catalytic reforming reaction of cellulose pyrolysis volatile matter. The synthesis of this catalyst introduces both of the mesopores and the metal active sites and this synergistic action enables the regulation of catalyst characteristics. This study is expected to shed light on improving the yield of light aromatic hydrocarbons during the catalytic reforming of biomass volatile and on regulating the product selectivity.
