Abstract: A process for purifying aromatic hydrocarbons contained in liquid products of refining petroleum fractions or liquid products of coal coking or low-temperature carbonization from non-aromatic hydrocarbons which comprises heat-treatment of said liquid products at a temperature ranging from 750.degree. to 950.degree. C. under a pressure within the range of from 1 to 10 atm in the presence of acyclic C.sub.2 -C.sub.4 hydrocarbons employed separately or in various combinations at a weight ratio between said acyclic hydrocarbons and said liquid products being of at least 0.3. The heat-treatment results in a vapor-gas mixture which is cooled to isolate a condensate containing predominantly aromatic hydrocarbons. The process is technologically simple and makes it possible to purify aromatic hydrocarbons practically without decomposition thereof.
