본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

Claims (6)

탄화수소 유분을 선택적인 수소화촉매와, 거의 모두가 탄솨수소 유분내에 용해되어 있는 수소존재하에 반응조건들하에서 색소체 및 색소체의 전구체들을 수소화 시키기에 충분한 시간동안 접촉시킴으로써 색 안정한 탄화수소 유분이 수득되도록 하는, 자체내에 함유되어 있는 임의의 올레핀계 및 방향족 탄화수소를 거의 수소화시킴이 없이 색소체 및 색소체의 전구체를 함유하는 탄화수소 유분의 색상 및 색 안정성을 선택적으로 개량시키기 위한 공정.Contacting the hydrocarbon fraction with a selective hydrogenation catalyst for a time sufficient to hydrogenate the pigment and precursors of the pigment under reaction conditions in the presence of hydrogen, which is almost all dissolved in the hydrocarbon oil, resulting in a color stable hydrocarbon fraction. A process for selectively improving the color and color stability of hydrocarbon fractions containing pigments and precursors of pigments with little hydrogenation of any olefinic and aromatic hydrocarbons contained therein. 제1항에 있어서, 반응 조건들이 온도 25°-250℃, 압력1-15기압, 액공간속도, 0.1-25hr­1및 전체 탄화수소유분을 기준으로 한 수소농도 10.1-3몰%인 공정.The process as claimed in claim 1, wherein the reaction conditions are a temperature of 25 ° -250 ° C., a pressure of 1-15 atmospheres, a liquid space velocity, 0.1-25 hr 1 and a hydrogen concentration of 10.1-3 mol% based on the total hydrocarbon fraction. 제1항에 있어서, 선택적인 수소화촉매가 알루미나, 시리카, 탄소, 알루미나-실리케이트, 천연 및 합성 점토 및 알칼리 토금속 산화물로 구성된 군으로부터 선택된 다공성 지지체상에 분산되어져 있는 Ⅷ 족 금속으로 구성되는 공정.The process of claim 1, wherein the selective hydrogenation catalyst consists of Group VIII metal dispersed on a porous support selected from the group consisting of alumina, silica, carbon, alumina-silicate, natural and synthetic clay and alkaline earth metal oxides. 제3항에 있어서, Ⅷ족 금속이 백금으로서 지지체의 0.1-5중량%에 해당되는 농도로 존재하는 공정.4. The process according to claim 3, wherein the Group VIII metal is present as platinum at a concentration corresponding to 0.1-5% by weight of the support. 제3항에 있어서, Ⅷ족 금속이 루테늄으로서 지지체의 0.1-5중량%에 해당되는 농도로 존재하는 공정.4. The process of claim 3, wherein the Group VIII metal is present as ruthenium at a concentration equivalent to 0.1-5% by weight of the support. 제3항에 있어서, 지지체가 탄소 또는 알루미나인 공정.The process of claim 3 wherein the support is carbon or alumina. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
