Research on Extraction and Analysis Methods of C10～C40 Petroleum Hydrocarbons from Refinery Waste Catalysts
The purpose of this study is to develop an efficient and environmentally friendly extraction and analysis method to achieve effective recovery of petroleum hydrocarbons from refinery waste catalysts.The research covers the entire process of solvent selection,optimization of extraction conditions,and analysis of extraction solutions using GC-FID technology.The results showed that by optimizing the extraction conditions,especially using dichloromethane as the extraction solvent and adjusting the extraction temperature to 60℃,the recovery rate of petroleum hydrocarbons could be significantly improved,reaching a maximum of 87.6%.
