The issues of feedstocks, product markets, and environmental emissions have continuously proposed a number of challenges for industrial evaluation of fresh fluid catalytic cracking (FCC) catalyst before its application in commercial units. In this work, a convenient method was proposed by comparing with the existing commercial equilibrium catalyst. A series of laboratory experiments for steam treatments and microactivity tests were established to collect reliable data, and the standalone catalyst or co-catalysts were assessed to show the evaluation process and the predicted unit performance. The results had deviation, but a consistent yield distribution than that of a commercial equilibrium catalyst. These evaluations and predictions would provide us with not only the view of hydrothermal stability and yield distribution at the unit level, but also the economic potential for fresh catalyst based on the existing industrial catalyst, which will provide refiners with industrial basis for further decisions.

研究新鲜FCC催化剂活性测试的新方法：从实验室规模到商业规模的实验和预测过程

原料，产品市场和环境排放问题一直为新鲜流化催化裂化（FCC）催化剂在商业化应用之前的工业评估提出了许多挑战。在这项工作中，通过与现有的工业平衡催化剂进行比较，提出了一种方便的方法。建立了一系列用于蒸汽处理和微活性测试的实验室实验，以收集可靠的数据，并对独立的催化剂或助催化剂进行了评估，以显示评估过程和预测的单元性能。结果具有偏差，但是与商业平衡催化剂相比具有一致的产率分布。这些评估和预测不仅可以为我们提供单位级别的水热稳定性和产量分布的观点，
