A process for extracting metals from aqueous solutions containing such metals comprising contacting such an aqueous solution with an asphaltene to extract at least one metal from the aqueous solution to the asphaltene, and recovering the thus extracted at least one metal from the asphaltene. Also disclosed is a process for sulfonating a petroleum fraction containing asphaltenes, the thus sulfonated asphaltenes being advantageously employable in the process for extracting at least one metal from an aqueous solution containing such metal.

Extraction of metals from aqueous solutions with asphaltenes

An improvement in the cetane number of diesel fuels is achieved through the addition of a small, but effective, amount of a dithiocarbamate or a sulfonamide.

Diesel fuel

A catalytically active composition is provided that is an intercalate of graphite, aluminum halide, and a Group VA metal halide. A process for preparing an intercalate of graphite, aluminum halide, and a Group VA metal halide is also provided.

Alkylation of olefins with paraffins utilizing aluminum halide and group

Catalytically active AlCl.sub.3 -graphite intercalate

Ethylene and/or propylene is dimerized by contacting the monoolefin with a catalyst formed by depositing a nickel complex such as bis(3-picoline)dichloronickel or bis(tributylphosphine)dichloronickel on a solid support such as silica-alumina. Preferably, an aluminum compound such as diethylaluminum chloride is also used in preparing the catalyst.
