PREPARING METHOD OF ABSORPTION OIL FOR REFINING OF COKE OVEN GAS HAVING IMPROVED YIELD AND THE ABSORPTION OIL THEREOF

摘要

PURPOSE: Provided is a method for effectively manufacturing absorption oil for coke oven gas purification and coke oven gas purification absorption oil manufactured by the same method. CONSTITUTION: The method comprises the steps of (a) causing cracking reaction of unsaturated ingredients by inputting coal tar into a zeolite catalyst reactor and maintaining a temperature of the reactor to 170-180C, (b) producing a first absorption oil by distilling the resultant material obtained at the step (a) using a first distillation tower at a temperature of 190-210C and cooling the same, thereby eliminating light oil from the resultant material of the step (a), and (c) removing pitch from the first absorption oil by distilling the first absorption oil using a second distillation tower at a temperature of 290-310C and cooling the same.
