Document Type and Number:
Japanese Patent JPH0635397
Kind Code:
B2
Abstract:
The present invention relates to a process for the preparation of an aromatic hydrocarbon mixture, wherein one or more mono-olefins with two to four carbon atoms per molecule or aliphatic hydrocarbon mixtures, at least 20 wt.% of which consists of the said olefins, are contacted in a first stage at a temperature of between 325 and 550 DEG C with a catalyst containing a crystalline metal siilcate wherein the reaction product of the first stage is separated into a C4<-> fraction and a C5<+> fraction, wherein the C4<->fraction is contacted in a second stage at a temperature of 450-700 DEG C that is at least 50 DEG C higher than the temperature employed in the first stage with a catalyst containing a crystalline gallium silicate. The relation between the C5<+> content and the aromatics content in the hydrocarbon mixture obtained is improved.
