  • Publication number: 20240067586
    Abstract: A process for dimerizing and oligomerizing olefins to distillate fuels which utilizes a solid acid catalyst for ethylene oligomerization in a first stage and a metal catalyst for further oligomerization in a second stage. Distillate fuels can be produced from the process. Oligomerized olefins may be recycled to the first stage oligomerization reaction to ensure sufficient oligomerization of smaller olefins.

  • Publication number: 20230399274
    Abstract: A process for converting naphtha to predominantly ethane comprising contacting a naphtha stream with a zeolitic catalyst comprising a noble metal and hydrogen to produce a light paraffin stream comprising ethane and propane; wherein the catalyst comprises at least about 0.005 wt % noble metal at a ratio of hydrogen to hydrocarbon of less than about 5. In a predominantly propane mode, the catalyst comprises about 0.005 wt % noble metal and operates at a reaction temperature of no more than about 450° C.

  • Publication number: 20230357654
    Abstract: 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.
