Producing bio-based aromatic substrates is becoming increasingly of (industrial) interest. In this mechanistic work, the gas phase conversion of the biomass tar chemical model compounds (5 wt% naphthalene/95 wt% 1-methylnaphthalene) over the different pristine/metal-modified zeolites in a continuous flow fixed bed reactor was investigated. Bifunctional redox acid process catalysts were synthesized by wet impregnation method. The effect of the W (/Ni) metal formulation additives to the pristine H-beta, H-USY, H-Y, and H-ZSM-5 in the hydrocracking, hydrogenation, and isomerization transformation reactions of the mixture under applied ambient pressure was firstly studied. Structure, texture, morphology, acidity, composition and properties were determined by various analytical techniques. Results showed that the highest catalytic activity with a comparison to others was established over the 20 wt% W-beta with 96.0 mol% of the selectivity to 2-methylnaphthalene, the 93.3 mol% reacted total reactant after the 24 h time on stream, where ethylene/propane were predominating (80.5 wt%), and facile manufacturing scalability. Detailed characterization methodologies have revealed that after the loading of W onto H-beta_support, a uniform functional distribution of particles, the dealumination of framework and strong interaction phenomena were observed, which led to an increase in the amount of Brønsted/Lewis/reduction surface sites, and hence, increase stability of the catalyst. In addition, equilibrium coke formation was detected, decreasing all estimated rates, undergoing also consequent external deactivation, blocking pores, and its burning-off regeneration being needed. While both spent W-modified (20 wt%)/unmodified H-beta/ZSM-5 exhibited the lowest carbon quantity, the same fresh materials possessed the uppermost hierarchy factors.

生产基于生物的芳香族底物越来越受到（工业）的关注。在这项机械工作中，研究了连续流动固定床反应器中生物质焦油化学模型化合物（5 wt% 萘/95 wt% 1-甲基萘）在不同原始/金属改性沸石上的气相转化。采用湿法浸渍法合成了双功能氧化还原酸工艺催化剂。W (/Ni) 金属配方添加剂对原始 H-β、H-USY、HY 和 H-ZSM-5 在常压下混合物的加氢裂化、加氢和异构化转化反应中的影响首先是学习了。结构、质地、形态、酸度、组成和性质由各种分析技术确定。结果表明，与其他物质相比，最高的催化活性是在 20 wt% W-β 上建立的，对 2-甲基萘的选择性为 96.0 mol%，在运行 24 小时后反应了 93.3 mol% 的总反应物，其中乙烯/丙烷占主导地位 (80.5 wt%)，并且易于制造可扩展性。详细的表征方法表明，在将 W 负载到 H-β_support 上后，粒子的均匀功能分布、框架脱铝和强相互作用现象被观察到，这导致 Brønsted/Lewis/还原表面位点的数量增加，从而提高催化剂的稳定性。此外，检测到平衡焦炭的形成，降低了所有估计的速率，也经历了随之而来的外部失活，堵塞了孔隙，并需要其燃烧再生。虽然用过的 W 改性 (20 wt%)/未改性 H-β/ZSM-5 表现出最低的碳量，但相同的新鲜材料具有最高的层次因素。
