Abstract
Aromatic hydrocarbons are recovered from benzole in pure form by first fractionating to obtain a lower boiling benzene fraction and a higher boiling fraction containing toluene and xylenes, then hydrofining each fraction. In a preferred embodiment forerunnings containing compounds more volatile than benzene are removed, e.g. cyclopentadiene and carbon disulphide. The benzene fraction should contain not more than 0.1% of toluene and other compounds less volatile than benzene; similar considerations apply to the toluene and xylene fraction. If desired the forerunnings may also be hydrofined together with the higher boiling fraction. Saturated materials are separated from the hydrofined products by fractionation and the higher boiling fraction may be separated into toluene and xylene. Specification 892,113 is referred to.
