PITCH MANUFACTURED FROM PETROLEUM PRODUCTS AND HIGH YIELD METHOD FOR MANUFACTURING THE SAME, AND HIGH PERFORMANCE CARBON ANODE MATERIALS USING THE SAME

摘要

PURPOSE: A manufacturing method of a pitch improves the yield and productivity of pitch while using petrochemistry byproducts. CONSTITUTION: A manufacturing method of a pitch for a negative electrode material comprises a step of heat-treating petrochemistry byproducts at high temperature and high pressure; and a step of adding a high-acidity catalyst material during the heat treatment. The petrochemistry byproducts is one or a mixture of two or more selected from pyrolysis fuel oil, heavy crude oil, extra heavy crude oil, vacuum residue oil, atmospheric residue oil, oil sand bitumen. The high-acidity catalyst material is zeolite, silica, or alumina. The gas is atmosphere, oxygen, nitrogen, carbon monoxide, or steam.
