Etymologies

Sorry, no etymologies found.

Examples

  • Catalytic hydrotreating processes such as hydrodesulfurization remove sulfur compounds from refinery product streams.

    Hydrocarbon chemistry

  • In a typical catalytic hydrodesulfurization unit, the feedstock is deaerated and mixed with hydrogen, preheated in a fired heater (600°-800° F) and then charged under pressure (up to 1,000 psi) through a fixed-bed catalytic reactor (Figure 12).

    Cracking

  • It is also used in large quantities in methanol production, in hydrodealkylation, hydrocracking, and hydrodesulfurization.

    Hydrogen

  • Hydrotreating for sulfur removal is called hydrodesulfurization.

    Cracking

  • It is also used in large quantities in methanol production, in hydrodealkylation, hydrocracking, and hydrodesulfurization.

  • Obviously there are pages there in front of you, but just to highlight a few, in hydrodesulfurization or HDS operations, this conversion of dibenzothiophenes to sulfones, this makes them easier to higher to treat.
