ASTM UOP602-89 催化剂的索氏萃取法

This method is for separating hydrocarbons from catalyst samples by extraction with a volatile solvent. This extraction is used to obtain a hydrocarbon and water free catalyst sample for carbon determination by UOP Method 703. It can also be used to determine the non-volatile hydrocarbon content of the sample, or to provide an extract for subsequent organic types analysis.

ASTM UOP254-87 流化床裂化催化剂的表观松密度

This method is for determining the apparent bulk density (ABD) of loosely packed fluid cracking catalyst in a size range of less than 200 祄 diameter. Apparent bulk density is the mass per unit volume of the particulate material.

Apparent Bulk Density of Fluid Cracking Catalyst

ASTM UOP410-85 用火焰发射或原子吸收分光光度法测定催化剂中钠

This method is for determining sodium in alumina and silica alumina base catalysts. It is also applicable to deposits, corrosion products and aqueous solutions. Loss on ignition is determined by UOP Method 275 to permit the calculation of results on a volatile-free basis. The lower limit of detection is approximately 0.0002 mass-%.
