Embodiment Construction

[0018] The present invention provides a method for increasing the yield or conversion of light olefins to increase the hydrocarbon component from a hydrocarbon feed to a gasoline blending cell. The process includes separating a naphtha feedstock into a first stream or cracker unit feed stream component that is more easily processed in a cracking unit and a second stream or reformer that is more easily processed in a reforming unit Unit feed stream components. The process includes the ability to convert components from a cracked stream to a reformed stream and convert components from a reformed stream to a cracked stream.

[0019] Processing of the naphtha feedstream can be used to produce light olefins and provide hydrocarbon components to gasoline blending pools or reforming components to produce aromatics to be sent to the aromatics complex. Such as figure 1 The basic process shown in includes splitting the naphtha feed stream into two parts, a second part 6 and a first pa...

Description

[0001] priority statement [0002] This application claims priority to U.S. Application Serial No. 14 / 260,812, filed April 24, 2014, which claims the benefit of U.S. Provisional Application No. 61 / 863,019, filed August 7, 2013, which The entire contents of are incorporated herein by reference. technical field [0003] The present invention relates to methods and systems for producing aromatics from heavier hydrocarbon streams. In particular, this method increases the yield and flexibility of producing aromatics and light olefins from hydrocarbon feedstocks. Background technique [0004] Reforming of petroleum raw materials is an important process for producing useful products. One important approach is to separate and upgrade hydrocarbons used in motor fuels, for example in gasoline production to generate a naphtha feedstream and to upgrade the octane number of the naphtha. However, hydrocarbon feed streams from virgin petroleum sources include the production of useful ch...
