METHOD OF LOW HYDROGENATION AND HYDRO-DESULFURIZATION OF PYROLYTIC GASOLINE AS INITIAL MATERIAL

摘要

1. A process for the selective hydrogenation of diolefins and sulfur compounds in the pyrolysis gasoline as a starting material, characterized by a concentration of diolefins and certain concentration of organic sulfur compounds, said process comprising: feeding a hydrocarbon stream, which comprises said pyrolysis gasoline as a starting material in the reactor loaded with highly active hydrotreating catalyst and operating under the selective hydrogenation, wherein said hydrocarbon stream to come into contact with said high activity hydrotreating catalyst, withdrawn from said reactor stream having a reduced concentration of diolefins and a reduced concentration of sulfur compounds, separating said reactor effluent to a portion of said reactor effluent and the remaining portion of said reactor effluent; and supply line of said certain portion of said reactor effluent stream to said reactor as recycle potoka.2. A method according to Claim. 1, wherein said concentration of diolefins than 3 wt.%, Said reduced diolefin concentration is less than 10 parts by weight per million and wherein the concentration of said organic sulfur compounds exceeds 50 parts by weight ppm, and a reduced concentration of said organic sulfur compounds is less than 3 parts by weight on million.3. A method according to claim. 2, wherein the reactor effluent at the outlet of said reactor is characterized by an aromatic content of at least 90 wt.% Of aromatic content with
