摘要

Catalytic reforming is the major process which produces the aromatic compound-rich mixtures and high grade motor gasoline.Thus,catalytic reformers within refineries are an important source of BTX (benzene,toluene,xylene),aromatics.Frequently high purity aromatics are recovered from these streams using modern extractive distillation or liquid extraction processes.Reforming process normally produces a small amount of olefins which will impair the quality of the product aromatics and refinate.Due to the residual content in diolefins and some olefins the reformer streams as well as the benzene and toluene after extractive distillation show a dark,yellowish color expressed by an acid wash color.
