摘要
根据催化裂化催化剂产品质量控制的需要,选择并设计了1套离心式气流分级系统,应用于30 kt/a压力式喷雾干燥成型微球生产装置,成功地将催化剂产品中小于20μm的细粉含量控制在3%以下,满足了催化剂生产工艺要求,取得了理想工业应用效果。
According to the quality control demand of FCC catalyst product,we choose and design a set of centrifugal airflow classification system,which is used in 30kt/a pressurized plant for production of spray dry shaped tiny balls.It successfully controls the content of fine powder with diameter <20μm in catalyst to below 3%,satisfying the requirements of catalyst production technology and obtaining ideal results in commercial application.
