1.1 本试验方法包括测定平衡或实验室失活的流化催化裂化（FCC）催化剂的活性和焦炭选择性。根据流化床反应器中柴油进料的质量百分比转化率评估活性。焦炭产率定义为沉积在催化剂上的碳质量，也表示为柴油进料的百分比。循环赛的范围将限于测定活性和焦炭。因此，所有其他分析均超出此范围，应注明为“可选” 1.2 以国际单位制或英寸-磅单位表示的数值应单独视为标准值。每个系统中规定的值不一定是精确的等价物； 因此，为确保符合本标准，每个系统应独立使用，且两个系统的值不得组合。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 流化床试验为评估催化裂化催化剂的相关性能提供了数据。由于结果受催化剂预处理、原料特性和操作参数的影响，本测试方法专门针对在相同条件下但在不同地点使用Kayser Technologies Advanced Catalystic Evaluation（ACE）装置测试常见催化剂和油时的准确性和精密度而编写。 4. , 5. 分析程序可能因现场而异。然而，预计不会出现重大变化。 注1: ASTM国际对与本标准提及的任何项目有关的任何专利权的有效性不持任何立场。 明确建议本标准的用户，确定任何此类专利权的有效性以及侵犯此类权利的风险完全由其自行负责。 5.2 准确度和精密度声明的标准反应温度为532 °C[990 °F]。在实践中可以使用其他反应温度；然而，在532以外的温度下开发的产量数据 °C[990 °F]将不一样。此外，在其他反应温度下，测试精度可能不同。

1.1 This test method covers determining the activity and coke selectivity of either equilibrium or laboratory deactivated fluid catalytic cracking (FCC) catalysts. The activity is evaluated on the basis of mass percent conversion of gas oil feed in a fluidized bed reactor. The coke yield is defined as the mass of carbon laid down on the catalyst, also expressed as a percent of the gas oil feed. The scope of the round robin will be limited to the determination of activity and coke. All other analyses are thus beyond this scope and should be noted as “optional.” 1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 The fluidized bed test provides data to assess the relative performances of FCC catalysts. Because results are affected by catalyst pretreatment, feedstock characteristics, and operating parameters, this test method is written specifically to address the accuracy and precision when a common catalyst and oil are tested under the same conditions but at different sites, using Kayser Technologies Advanced Catalytic Evaluation (ACE) unit. 4 , 5 Analytical procedures may vary among the sites. However, significant variations are not expected. Note 1: ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. 5.2 The standard reaction temperature for purposes of the accuracy and precision statement is 532 °C [990 °F]. Other reaction temperatures can be used in practice; however, yield data developed at temperatures other than 532 °C [990 °F] will not be the same. Also, test precision may be different at other reaction temperatures.
