Components of a sludge produced from a crude oil were analyzed by GPC, TLC-FID, IR and <SUP>1</SUP>H-NMR after solvent fractionation. The sludge consisted of hexane soluble oil (54%) and hexane insoluble-benzene soluble asphaltene (44%), high content of the latter component suggesting its concentration in the sludge . The oil was essentially long-chain paraffins (ay molecular weight: -2100), while the asphaltene was polar hydrocarbons (ay molecular weight: -4000) with least aromatic constituents . Insolubility of the asphaltene was found partly due to its metal ion contaminants of which removal increased some solubility in hexane. The metal ions may coordinate to the polar parts. The asphaltene in the crude was adsorbd on the iron oxide or silica-alumina to precipitate at the bottom of crude container, forming the sludge . Water was found to accelerate the precipitation. The oil fraction was occluded into the micelle by the paraffinic moiety of the asphaltene to constitute a part of the sludge. A significant portion of such components was present in the crude oil, while the other portion was produced by air oxidation, probably being catalyzed by soluble metal ions.
