摘要:
A process is provided for producing high purity benzene and high purity paraxylene from a hydrocarbon feed. In one aspect, the process comprises: (a) reforming a hydrocarbon feed using either a monofunctional catalyst or a bifunctional catalyst to provide one or more reformate streams; (b) fractionating the reformate stream to provide a toluene stream, a benzene stream, and a xylene stream; (c) subjecting the toluene stream to disproportionation; (d) purifying the benzene stream by extraction followed by distillation to provide a high purity benzene product; and (e) purifying the xylene stream by simulated moving bed countercurrent adsorption followed by crystallization to provide a high purity paraxylene product.
