  • CATALYSTS AND PROCESS FOR CATALYTICALLY CONVERTING NAPHTHA TO LIGHT OLEFINS
    Publication number: 20250214067
    Abstract: A zeolitic catalyst and a process for its use is provided where the metal, preferably platinum, on the catalyst is not well dispersed as shown by low levels of H2 chemisorption, and low chemisorption hydrogen to platinum ratios. In a process for converting naphtha to light olefins that comprises contacting a naphtha stream with a zeolitic catalyst to produce a light paraffin stream at conditions which dehydrogenate the naphtha to olefins, interconvert the olefins to lighter olefins and hydrogenate the lighter olefins to produce a light paraffin stream comprising ethane and propane, this catalyst produces a higher proportion of ethane.

  • PROCESS FOR CATALYTICALLY CONVERTING NAPHTHA TO LIGHT OLEFINS WITH PREDOMINANT MODES
    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. The process can be switched between modes depending on the desires of the operator.
