  • Patent number: 10577293
    Abstract: Processes and apparatuses for producing para-xylenes are provided. The processes comprises providing a hydrocarbon stream comprising C7+ hydrocarbons. The hydrocarbon stream is separated to provide a C8 aromatics stream and an ortho-xylene rich stream. The C8 aromatics stream is passed to a para-xylene separation unit for separating para-xylene to provide a para-xylene stream and a raffinate stream. At least a portion of the raffinate stream is passed to a first isomerization unit to provide a first isomerization effluent, wherein the first isomerization effluent is produced in the presence of an ethylbenzene (EB) isomerization catalyst. At least a portion of the ortho-xylene rich stream is contacted with an isomerization catalyst in a second isomerization unit in liquid phase at isomerization conditions in substantial absence of hydrogen to produce a second isomerization effluent.

  • Patent number: 10563139
    Abstract: Processes for hydrotreating an effluent from a slurry hydrocracking process are described. Different streams are formed from the SHC effluent, and different hydroprocessing conditions are applied to the streams, e.g., more severe conditions are applied to streams which need additional hydroprocessing, while less severe conditions are applied to streams which do not need as much hydroprocessing. Common equipment is shared between different hydroprocessing steps.

  • Patent number: 10557091
    Abstract: A reforming reactor and process of using same in which residence time of feed within a chamber of a reactor is shortened. Feed is injected into the reactor into a non-reactive zone. The non-reactive zone has two portions, a first portion receiving the feed, and a second portion receiving a purge gas. The purge gas will flow from the second portion to the first portion to prevent flow of the feed from the first portion to the second portion. The combined gas may be passed to a reaction zone for catalytic reforming. The first portion and the second portion may be separated by a baffle.
