SELECTIVE HYDROGENATION PROCESS FOR IMPROVING THE COLOR STABILITY OF A HYDROCARBON FRACTION

The color and color stability of a color-unstable hydrocarbon fraction is improved by contacting the hydrocarbon fraction with a selective hydrogenation catalyst in the presence of hydrogen, substantially all of which is dissolved in the hydrocarbon fraction, the contacting being carried out at reac...

Summary:The color and color stability of a color-unstable hydrocarbon fraction is improved by contacting the hydrocarbon fraction with a selective hydrogenation catalyst in the presence of hydrogen, substantially all of which is dissolved in the hydrocarbon fraction, the contacting being carried out at reaction conditions selected to result in the selective hydrogenation of conjugated unsaturates.
