Abstract
Para-xylene (PX), as a pivotal chemical feedstock, plays an indispensable role in ensuring nation energy strategic security and propelling the low-carbon and green development of the chemical industry. The review systematically summarizes the recent advancements in catalysts for the direct conversion of syngas into p-xylene-enriched aromatics, focusing on three distinct catalytic systems: the Fischer-Tropsch synthesis catalyst/zeolite coupling system, the methanol synthesis catalyst/zeolite synergistic system, and the dual engine driven/zeolite catalytic system. Through a comprehensive and in-depth analysis of critical parameters, including the electronic structure features of active components, the synergistic action mechanism of promoters, and the pore topology of zeolite within each catalytic system, the governing principles of catalytic activity, selectivity, and stability are thoroughly revealed. Simultaneously, based on the reaction intermediate evolution pathways, the reaction mechanisms involving olefin, methanol, and olefin-methanol dual intermediate routes are systematically explored. The current scientific bottlenecks confronted by the catalyst systems, such as the intricate challenge of achieving coordinated optimization of activity and stability, and the lack of clarity in the regulatory mechanism of PX directional selectivity, are meticulously expounded. Building upon these identified issues, prospective research directions are comprehensively summarized.
期刊介绍：
Journal of Fuel Chemistry and Technology (Ranliao Huaxue Xuebao) is a Chinese Academy of Sciences(CAS) journal started in 1956, sponsored by the Chinese Chemical Society and the Institute of Coal Chemistry, Chinese Academy of Sciences(CAS). The journal is published bimonthly by Science Press in China and widely distributed in about 20 countries. Journal of Fuel Chemistry and Technology publishes reports of both basic and applied research in the chemistry and chemical engineering of many energy sources, including that involved in the nature, processing and utilization of coal, petroleum, oil shale, natural gas, biomass and synfuels, as well as related subjects of increasing interest such as C1 chemistry, pollutions control and new catalytic materials. Types of publications include original research articles, short communications, research notes and reviews. Both domestic and international contributors are welcome. Manuscripts written in Chinese or English will be accepted. Additional English titles, abstracts and key words should be included in Chinese manuscripts. All manuscripts are subject to critical review by the editorial committee, which is composed of about 10 foreign and 50 Chinese experts in fuel science. Journal of Fuel Chemistry and Technology has been a source of primary research work in fuel chemistry as a Chinese core scientific periodical.
