摘要:: 摘要：以蜡油作为原料，考察了 β分子筛催化剂在提升管反应器内催化剂性质和产物分布达

到稳定所需的时间。实验结果表明，β分子筛催化剂的主要理化性质所达到稳定的时间有所

不同，受此影响，其各类产物也未在同一时间达到稳定。此外，由于催化剂本身的性质，β分

子筛催化剂对于蜡油的转化能力弱于催化裂化中常见的Y型分子筛催化剂，但是产物中乙烯

和丙烯的收率相比之下具有明显优势，体现出β分子筛催化剂增产高附加值产品的性能。

Abstract: This study utilized wax oil as a raw material and a riser reactor to evaluate the time for the characteristics of β zeolite cat⁃

alysts and product dispersion to achieve stability. The experimental results reveal that the primary physicochemical attributes of β

zeolite catalysts acquire stability at different periods. As a result, their varied products do not achieve stability at the same time. Fur⁃

thermore, β zeolite catalyst has a lower conversion capacity for wax oil compared to Y zeolite catalyst due to its characteristics. How⁃

ever, the yield of ethylene and propylene in the product has a substantial advantage over it, showing the efficacy of β zeolite catalyst

in enhancing the production of high value-added products.
