Abstract:
     The present invention relates to a kind of desulfurizer for reforming raw oil at low temp. and liq. phase. Using diatomaceous earth, silicon, dioxide and dialuminium trioxide as carrier and sesbania powder, organic acid, inorganic acid as well as surface active agent as compounded improver. The desulfurizer is made of nickel, above-mentioned carrier and the compounded improver. The desulfurizer after reduction can remove organic sulphur (e.g. mercaptan) and hydrogen sulfide from hydrocarbon oil at low temperature and under non-hydrogenative conditions. It is especially useful for sulfur removal of raw oil for polymetallic reforming. After sulfur removal sulfur content in the oil may be decreased to below 0.2 ppm. It is also useful for sulfur removal of gasoline, kerosine, diesel oil, hydrocarbon gas, hydrogen and hydrogen-hydrocarbon gaseous mixture.
