<p>PURPOSE:To selectively and effectively remove extremely small quantities of mercury in a hydrocarbon base oil containing mercury, by adding a tin compound into the oil. CONSTITUTION:(A) hydrocarbon base oil containing preferably <=400-600ppb (especially <=100-150ppb) mercury is blended with (B) a tin compound consisting of tin halide, preferably stannous halide and/or stannic halide and/or tin oxide powder, preferably aqueous solution thereof and mercury is removed. The hydrocarbon base oil is widely applicable in reactions using catalyst after hydrogenating reactions, because of no content of catalytic poisoning component.</p> |
