摘要： A process increases the concentration of normal paraffins in a feed stream comprising separating a naphtha feed stream into a normal paraffin rich stream and a non-normal paraffin rich stream. A naphtha feed stream may be separated into a normal paraffin stream and a non-normal paraffin stream. An isomerization feed stream is taken from the non-normal paraffin stream and isomerized over an isomerization catalyst to convert non-normal paraffins to normal paraffins and produce an isomerization effluent stream. The isomerization effluent stream may be separated into a propane stream and a C4+ hydrocarbon stream optionally in a single column. The C4+ hydrocarbon stream may be recycled to the step of separating a naphtha feed stream.

摘要： A process increases the concentration of normal paraffins in a feed stream comprising separating a naphtha feed stream into a normal paraffin rich stream and a non-normal paraffin rich stream. The non-normal paraffin rich stream is isomerized over a first isomerization catalyst to convert non-normal paraffins to normal paraffins and produce a first isomerization effluent stream. An iso-C4 stream is separated from the first isomerization effluent stream and isomerized over a second isomerization catalyst to convert iso-C4 hydrocarbons to normal C4 hydrocarbons and produce a second isomerization effluent stream. The normal paraffin rich stream, the normal paraffins in the first isomerization effluent stream and/or the second isomerization effluent stream may be fed to a steam cracker.

摘要： A process for producing light olefins comprising thermal cracking. Hydrocracked streams are thermally cracked in a steam cracker to produce light olefins. A pyrolysis gas stream is separated into a light stream and a heavy stream. A light stream is separated into an aromatic naphtha stream and a non-aromatic naphtha stream. The aromatics can be saturated and thermally cracked. The integrated process may be employed to obtain olefin products of high value from a crude stream.

摘要： A process for converting naphtha to light olefins comprises contacting a naphtha stream with a zeolitic catalyst to produce a light paraffin stream. The light paraffin may be separated into an ethane stream and a propane stream. The ethane in the ethane stream may be converted into ethylene, and the propane in the propane in the propane stream may be converted into propylene. The light paraffin stream may also be separated into a heavy stream which may be recycled back to the contacting step.

摘要： A process for increase conversion and yield and selectivity to normal paraffins by reducing the hydrogen to hydrocarbon ratio for paraffin feeds with substantial butanes. The process works best with a low concentration of heavies and cyclics in the isomerization feed. High normal ratios of equilibrium, isobutane conversion, normal paraffins yield and selectivities are achieved for naphtha feed at low ratios of hydrogen to hydrocarbons.

摘要： A process for increasing conversion and selectivity to normal paraffins is achieved by reducing the hydrogen to hydrocarbon ratio for paraffin feeds with substantial butanes. A separator may be used to remove excess hydrogen from a first isomerate before a second isomerization step that may isomerize additional butanes perhaps generated in the first isomerization step.
