Standard Practice for Sample Preparation of Fluid Catalytic Cracking Catalysts, Catalytic Materials, and Zeolites for Elemental Analysis by Inductively Coupled Plasma Optical Emission Spectroscopy 用电感耦合等离子体光发射光谱法进行元素分析用流体催化裂化催化剂、催化材料和沸石样品制备的标准实施规程
发布日期: 2022-08-01
1.1 本规程涵盖了制备流化催化裂化催化剂(FCC)和交换沸石材料样品的均匀溶解技术,以通过电感耦合等离子体发射光谱(ICP-OES)进行分析。这些技术描述了利用酸消化和硼酸盐融合制备样品的众所周知、广泛使用的实验室实践的标准化方法。本规程适用于新鲜和平衡FCC催化剂、用于制造催化剂的催化材料和交换沸石材料。 1.2 单位- 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.3 本标准并不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建立适当的安全、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 催化剂和催化剂材料的化学组成是催化剂性能的一个重要指标,也是评估催化裂化工艺参数的一个有价值的工具。本规程将有助于催化剂制造商和炼油厂进行质量验证和性能评估,并有助于州和联邦各级环境主管部门对各种合规计划进行评估和验证。 3. , 4. , 5. 5.2 催化剂和催化剂类型材料很难制备用于ICP分析,尽管本实践中介绍的技术很常见,但实验室之间在样品预处理和消化配方方面存在很大差异。 本规程旨在标准化这些变量,以便于制造商、炼油商和监管机构之间使用比较数据。
1.1 This practice covers uniform dissolution techniques for preparing samples of fluid catalytic cracking catalysts (FCC) and exchanged zeolitic materials for analysis by Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES). These techniques describe standardized approaches to well-known, widely used laboratory practices of sample preparation utilizing acid digestions and borate salt fusions. This practice is applicable to fresh and equilibrium FCC catalysts, catalytic materials used to manufacture catalyst, and exchanged zeolite materials. 1.2 Units— The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 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 chemical composition of catalyst and catalyst materials is an important indicator of catalyst performance and is a valuable tool for assessing parameters in a FCCU process. This practice will be useful to catalyst manufacturers and petroleum refiners for quality verification and performance evaluation, and to environmental authorities at the state and federal levels for evaluation and verification of various compliance programs. 3 , 4 , 5 5.2 Catalysts and catalyst type materials are difficult to prepare for analysis by ICP, and although the techniques presented in this practice are common, there is wide variation among laboratories in sample pretreatment and digestion recipes. This practice is intended to standardize these variables in order to facilitate the utility of comparative data among manufacturers, refiners, and regulatory agencies.
