    摘要: It has been discovered that a dual bed process using two different catalysts for the selective hydrogenation of acetylene and/or methyl acetylene (MA) and/or propadiene (PD) in a light olefin-rich feedstream can be accomplished with less selectivity to making oligomers (green oil) as compared with existing commercial technologies, if a low oligomers selectivity catalyst is used first in the process. A palladium catalyst may be used as a second, sequential catalyst to further hydrogenate acetylene and/or MAPD while consuming at least a portion of the balance of the hydrogen present. The first catalyst should be different from the second catalyst.

    摘要: Crude oil fractions, fossil fuels, and organic liquids in general in which it is desirable to reduce the levels of fused-ring compounds, aromatics, and olefins are combined with an aqueous phase to form an emulsion and treated with ultrasound with the effect of opening rings in the fused-ring compounds, saturating aromatics, and converting the olefins to paraffins. In fossil fuels and crude oil fractions, the process raises the API gravity, and in diesel fuels, the process raises the cetane index and thereby improves performance. In fuels and fractions with sulfur-containing and nitrogen-containing components, the process reduces the level of these compounds. The process can be performed both with and without the added presence of hydrogen peroxide. The invention is performed either as a continuous process or a batch process.
