Definitions
- the drawing is a simplified schematic process flow diagram illustrating a preferred embodiment of the present invention, wherein dimethylbutanes are removed downstream from the dehydrocyclization reaction zone.
- the Group VIII metal or metals may be introduced to the catalyst such as the zeolite component of the catalyst, by synthesis, impregnation, or ion exchange carried out in aqueous solution of an appropriate salt.
- the operation may be carried out simultaneously or sequentially.
- the fresh feed is composed of the following components: C 5 -, dimethylbutanes (DMBs), 2-methylpentanes, 3-methylpentanes, methylcyclopentane, n-hexane, cyclohexane.
- DMBs dimethylbutanes
- 2-methylpentanes 2-methylpentanes
- 3-methylpentanes methylcyclopentane
- n-hexane cyclohexane
- cyclohexane methylcyclopentane
- n-hexane cyclohexane
- cyclohexane methylcyclopentane
- n-hexane n-hexane
- cyclohexane cyclohexane
- the relative feed compositions for the two cases are shown below, on a liquid volume percent basis. (Weight percent for these type feeds would be close to liquid volume percent.)
