  • n. a process for lowering the sulfur content of petroleum and similar products by catalytic hydrogenation, sulfur compounds being converted to hydrogen sulfide

Etymologies

Sorry, no etymologies found.

Examples

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

    Hydrocarbon chemistry

  • Hydrotreating for sulfur removal is called hydrodesulfurization.

    Cracking

  • 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

  • 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.

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

  • CORPUS CHRISTI - Valero Energy Corp. restarted its hydrodesulfurization unit on Wednesday at its Corpus Christi refinery complex after unplanned maintenance shut it down for a day.

  • Scientists have tried to improve hydrodesulfurization, or HDS, but have made no progress.

  • To address these issues, the PNNL team has developed a small-scale hydrodesulfurization units that is coupled with a steam reformer operating at 15-20 atm.

  • Although hydrodesulfurization (HDS), a high-pressure, high-temperature catalytic process that converts organic sulfur to hydrogen sulfide gas, can remove various types of sulfur compounds, some types of heterocyclic sulfur compounds existing in petroleum cannot be removed.
