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.
