MERCURY REMOVAL FROM LIQUID HYDROCARBON FRACTION |
摘要 |
Mercury is removed from a liquid hydrocarbon fraction by effecting high-temperature heat treatment to convert an organic mercury compound into an inorganic mercury compound or elemental mercury, removing a higher molecular weight component from the fraction, removing water from the fraction, and thereafter contacting the fraction with an adsorbent in the form of active carbon having calcium or a calcium compound supported thereon. Although only a minor amount of mercury is contained in the liquid hydrocarbon fraction, mercury can be efficiently removed at low cost on an industrial large scale, achieving an extremely low mercury concentration.
