  • Publication number: 20230132471
    Abstract: The present application relates to a process for cracking a hydrocarbon feedstock, using to the largest extent electrically powered equipment where the power is obtained from renewable sources or low-carbon sources. In particular, it relates to a process for cracking a hydrocarbon feedstock, including bringing the hydrocarbon feedstock and dilution steam to supersonic velocities in the reactor, followed by applying a shockwave to induce cracking of the hydrocarbon feedstock, to convert at least a part of the hydrocarbon mixture to produce olefins.
    Type: Application

  • Publication number: 20230133789
    Abstract: The present application relates to a process for cracking a hydrocarbon feedstock, using to the largest extent electrically powered equipment where the power is obtained from renewable sources or low-carbon sources. In particular, it relates to a furnace for steam cracking a hydrocarbon feedstock, wherein the furnace comprises one or more tubes for transporting the hydrocarbon feedstock and dilution steam; and an electrically heated infrared emitter for transferring heat to the tubes. It also relates to a process for steam cracking a hydrocarbon feedstock using infrared radiation.

  • Publication number: 20070031789
    Abstract: The present invention relates to an aesthetic dental restoration having a layered structure, which dental restoration has the appearance of a natural tooth. In addition, the present invention relates to a method for preparing such dental restorations. Particularly, the invention is based on the control of interaction between opalescence and fluorescence.
