  "id": "MLC-T-CHM-001726",
  "term": "Catalytic hydrodesulfurization",
  "field": "Chemistry",
  "definition": "A catalytic process for removing sulfur from petroleum fractions by reacting them with hydrogen. In this process, organosulfur compounds are converted into hydrogen sulfide and the corresponding hydrocarbon over a solid catalyst, typically containing molybdenum and cobalt or nickel on an alumina support. The resulting hydrogen sulfide is then separated and converted to elemental sulfur, a process mandated by environmental regulations to reduce sulfur dioxide emissions.",
