  • METHOD AND APPARATUS FOR CATALYST SAMPLING
    Publication number: 20180275020
    Abstract: The present subject matter relates generally to methods and an apparatus for catalyst sampling for measuring and testing. More specifically, the present subject matter relates to methods for sampling a catalyst where solid material samplers are used in between reactors or regeneration zones to gain knowledge of the state of the catalyst at different points in the hydrocarbon conversion process.

  • Catalytic reforming process with sulfur preclusion
    Patent number: 5507939
    Abstract: A hydrocarbon feedstock is catalytically reformed to effect dehydrocyclization of paraffins in a process combination comprising a first reforming zone, a sulfur-removal zone containing a mixed reforming catalyst and sulfur sorbent comprising a manganese component to preclude sulfur from the feed to a second reforming zone. The process combination shows substantial benefits over prior art processes in achieving reforming-catalyst stability.
    Type: Grant

  • Catalytic reforming process with sulfur preclusion
    Patent number: 5300211
    Abstract: A hydrocarbon feedstock is catalytically reformed to effect dehydrocyclization of paraffins in a process combination comprising a first reforming zone and a sulfur-removal zone utilizing a manganese component to preclude sulfur from the feed to a second reforming zone. The process combination shows substantial benefits over prior art processes in the stability of the extremely sulfur-sensitive catalyst utilized in the second reforming zone.

  • Process for the dehydrocyclization of aliphatic hydrocarbons
    Patent number: 4795846
    Abstract: An improved dehydrocyclization process for the selective conversion of light hydrocarbons to aromatics is presented. The activity of a catalyst containing nonacidic L-zeolite is greatly enhanced by the addition of water, water precursors, or mixtures thereof to the reaction zone during the dehydrocyclization reaction. Addition of between 10 and 100 wt. ppm H.sub.2 O results in a higher product yield of aromatics with increased product octane.
