Extraction of oil heteroatomic compounds using metal powders

摘要

The paper presents results of scanning electron microscope (SEM) investigations, differential thermal and elemental analyses, and infrared (IR) spectroscopy of micron powders obtained by thermal decomposition of cupric and nickel oxalates before and after their blending with oil. The oil treatment modifies the powder compositions, heteroorganic compounds extracted from oil are observed on their surface. The analysis shows that materials based on copper and nickel micron powders can be used for the prepurification of crude hydrocarbons from heteroatomic compounds.
