  • Patent number: 11365358
    Abstract: An integrated process for conversion of a hydrocarbon stream comprising light naphtha to enhanced value products. The process includes passing the hydrocarbon stream through a first reactor, the first reactor being a catalytic bed reactor with a dual-function catalyst to simultaneously reform light naphtha to BTEX and crack light naphtha to ethane, propane, and butanes. Further, the process includes passing an effluent of the first reactor to a gas-liquid separating unit to generate a liquid stream and a gas stream, and passing the gas stream to a gas separator unit to remove hydrogen gas and methane and generate an enhanced gas stream. The process further includes passing the enhanced gas stream through a second reactor, the second reactor being a pyrolysis unit operated at steam cracking conditions to convert ethane, propane, and butanes in the enhanced gas stream to light.

  • Publication number: 20220017829
    Abstract: A process for converting a hydrocarbon feed to olefins includes passing the hydrocarbon feed to a distillation system to separate the hydrocarbon feed to produce a light gas stream, a plurality of distillate fractions, and a residue. The process further includes passing at least one of the distillate fractions to a steam catalytic cracking system that includes at least one steam catalytic cracking reactor that is a fixed bed reactor containing a nano-zeolite cracking catalyst. The steam catalytic cracking system contacts the one or more of the plurality of distillate fractions with steam in the presence of the nano-zeolite cracking catalyst, which causes steam catalytic cracking of at least a portion of hydrocarbons in the at least one distillate fraction to produce a steam catalytic cracking effluent comprising the olefins.
