Abstract

The present invention discloses a new utilization process for catalytic cracking slurry oil. According to the process, catalytic slurry oil is subjected to vacuum distillation to obtain light slurry oil and topped slurry oil, wherein a distillation outlet temperature is 360-480 DEG C; physical and chemical indicators of the light slurry oil are detected, and are compared with marine fuel oil standards, wherein the light slurry oil meeting the standards is directly adopted as marine residual fuel oil, or a diesel component is adopted to blend to meet the standards so as to adopt the light slurry oil as marine distillate fuel oil, or a residue oil component is adopted to blend to meet the standards so as to adopt the light slurry oil as marine residual fuel oil. The marine fuel oil standards are the national standards ZB / T17411-1998. The diesel component is one or a plurality of materials selected from normal pressure second side oil, normal pressure third side oil, a catalytic diesel and a hydrogenated diesel, and is blended into the light slurry oil, wherein the use amount of the diesel component is 30-95% of the total amount. The residue oil component is one or a plurality of materials selected from vacuum residue oil, viscosity reduction residue oil and deoiled asphalt, and is blended into the light slurry oil, wherein the use amount of the residue oil component is 5-85% of the total amount. The new process of the present invention has characteristics of simple process, wide raw material, and product diversification.

Description

technical field [0001] The invention relates to the field of petrochemical industry, in particular to a new process for utilizing catalytic cracking oil slurry. Background technique [0002] Catalytic cracking oil slurry refers to the material extracted from the bottom of the distillation tower of the catalytic cracking unit, which is usually called catalytic oil slurry in the oil refining industry. Usually, the oil slurry is used for returning to catalytic cracking for further cracking, blending as boiler fuel or other fuels, as raw material for coking, as raw material for asphalt, etc. Since the main component of oil slurry is condensed-ring aromatics with short side chains, the main contribution to catalytic cracking is low-value coke and gas. Even if the liquid product is obtained, it is aromatics with poor properties and poor stability, so oil slurry is not catalytic cracking. Good material for installation. The oil slurry contains catalyst dust, and it is used as boi...
