摘要
对近年来纳米ZSM-5沸石在合成、物化性能及催化性能方面的研究进展进行了综述。与微米ZSM-5相比,纳米ZSM-5的孔道短,晶间孔丰富,酸量多且外表面酸量占的比例大,抗积炭失活和抗硫中毒性能良好。
The research progresses in synthesis, physical and chemical properties as well as catalytic performance on nanoscale ZSM-5 were summarized. Compared with conventional microscale HZSM-5, nanoscale HZSM-5 has shorter channel length, more abundant secondary pore, higher percentage of the external acid sites, excellent anti-coke formation ability, and anti-sulfur poisoning ability.
