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, 8220;Carbon on Catalysts by Induction Furnace Combustion and Infrared Detection.8221; It can also be used to determine the non-volatile hydrocarbon content of the sample, or to provide an extract for subsequent analysis. The use of an automated system is described in the Appendix. For self-heating samples, refer to the drying procedure in the Appendix.
