Standard Test Method for Palladium in Molecular Sieve Catalyst by Atomic Absorption

ASTM D5154-10 微活性试验法测定流化催化裂化(FCC)催化剂的活性和选择性的标准试验方法

The microactivity test provides data to assess the relative performance of FCC catalysts. Because results are affected by catalyst pretreatment, feedstock characteristics, test equipment, and operating parameters, adherence to this test method is a prerequisite for correct interpretation of results. Apparatus, test conditions, and analytical procedures actually used should closely resemble those described in this test method. Significant variations in apparatus, test conditions and/or analytical procedures may result in activity and selectivity data which do not correlate with data developed by other laboratories on identical catalyst/feedstock samples. The standard method reaction temperature is 960°F (516°C). Other reaction temperatures can be used; however, catalyst selectivity data developed at temperatures other than 960°F (516°C) may not correlate with selectivity data developed at 960°F (516°C). Also, precision at other reaction temperatures may change compared to data obtained at 960°F (516°C).1.1 This test method covers determining the activity and 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 in a microactivity unit.

Standard Test Method for Palladium in Molecular Sieve Catalyst by Wet Chemistry

ASTM D4464-10 用的激光散射法测定催化材料粒度分布的标准试验方法

It is important to recognize that the results obtained by this test method or any other method for particle size determination utilizing different physical principles may disagree. The results are strongly influenced by physical principles employed by each method of particle size analysis. The results of any particle sizing method should be used only in a relative sense and should not be regarded as absolute when comparing results obtained by other methods. Particularly for fine materials (that is, average particle size < 20 μm), significant differences are often observed for laser light scattering instruments of different manufacturers. These differences include lasers of different wavelengths, detector configuration, and the algorithms used to convert scattering to particle size distribution. Therefore, comparison of results from different instruments may be misleading. Light scattering theories (Fraunhofer Diffraction and Mie Scattering ) that are used for determination of particle size have been available for many years. Several manufacturers of testing equipment now have units based on these principles. Although each type of testing equipment utilizes the same basic principles for light scattering as a function of particle size, different assumptions pertinent to application of the theory and different models for converting light measurements to particle size, may lead to different results for each instrument. Furthermore, any particles which are outside the size measurement range of the instrument will be ignored, causing an increase in the reported percentages within the detectable range. A particle size distribution which ends abruptly at the detection limit of the instrument may indicate that particles outside the range are present. Therefore, use of this test method cannot guarantee directly comparable results from different types of instruments. This test method can be used to determine particle size distributions of catalysts and supports for materials specifications, manufacturing control, and research and development work. For fine materials (that is, average particle size < 20 μm), it is critical that Mie Scattering Theory be applied. This involves entering an “optical model” consisting of the “real” and “imaginary” refractive indices of the solid at the wavelength of the laser. The “imaginary” refractive index is also referred to as the “absorbance,” as it has a value of zero for transparent materials such as glass beads. For common materials and naturally occurring minerals (for example, kaolin), these values are known and published, and usually included in the manufacturer’s instrument manual (for example, as an appendix). For example, kaolinite measured at 589.3 nm has a “real” refractive index of 1.55. The absorbance (imaginary component) for minerals and metal oxides is normally taken as 0.001, 0.01 or 0.1. Many of the published values were measured at 589.3 nm (sodium light) but often values at other wavelengths are also given. Extrapolation, interpolation, or estimation to the wavelength of the laser being used can therefore be made. 1.1 This test method covers the determination of the particle size distribution of catalyst and catalyst carrier particles and is one of several found v......

ASTM D7442-08a 通过感应耦合等离子体-原子发射光谱测量法进行元素分析用流化床催化裂化催化剂的试样制备的标准实施规程

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. 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.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 Atomic Emission Spectroscopy (ICP-AES). 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 and exchanged zeolite materials. 1.2 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 and health practices and determine the applicability of regulatory limitations prior to use.
