Production of naphthalene from liquid products of the pyrolysis of hydrocarbon feedstock
Naphthalene is produced in the USSR only in the processing of coal tar. Liquid products of pyrolysis of hydrocarbon feedstocks are promising raw materials for its production; the output of these will continuously increase in connection with the startup of large-capacity ethylene plants and the planned use of gas oil as a feedstock for pyrolysis. This will lead to a significant increase of the potential naphthalene concentration in the liquid pyrolysis products. 6-6.5 thousand t naphthalene per year can be extracted on an EP-300 installation in pyrolysis of gasoline, and from 18-24 thousand t per year can be obtained on a facility of the same capacity for ethylene using diesel fuel as the feedstock.
