Abstract:
A process preparing an aromatic product comprising xylene, the process comprising: a) cracking a feedstock to obtain a cracker effluent comprising olefins and aromatics; b) converting an oxygenate feedstock in an oxygenate-to-olefins conversion system, comprising a reaction zone in which an oxygenate feedstock is contacted with a catalyst to obtain a conversion effluent comprising benzene, toluene, xylene and olefins; c) combining at least part of the cracker effluent and at least part of the conversion effluent to obtain a combined effluent, the combined effluent comprising aromatics; d) separating at least a portion of the benzene and/or toluene from the combined effluent to form a benzene and/or toluene stream; e) separating the olefins from the combined effluent; f) separating xylene from the combined effluent to form a xylene stream; and g) recycling at least a part of the benzene and/or toluene streams as recycled aromatics to step b).
