Abstract
One exemplary embodiment can be a method for processing polyisopropylbenzene for producing cumene. The method can include passing a transalkylation feed stream to a transalkylation zone, and passing a reaction product to a separation zone. Typically, the separation zone produces a stream including di-isopropylbenzene, tri-isopropylbenzene, and one or more heavy compounds. Moreover, the stream may include at least about 0.7%, by weight, of the one or more heavy compounds based on the weight of the di-isopropylbenzene, tri-isopropylbenzene, and the one or more heavy compounds in the stream, and at least a portion of the stream is recycled to the transalkylation zone.
