Mercury removal from coal-fired flue gas of high-sulfur petroleum coke activated by pyrolysis and mechanochemical method

With the signing of the Minamata Convention, the task of reducing mercury emission from coal-fired power plants is imminent. High-sulfur petroleum coke (PC), a by-product of the petrochemical industry, has the potential to prepare high-performance mercury removal adsorbents. The effects of activation parameters of pyrolysis, mechanochemistry, pyrolysis + mechanochemistry on the mercury removal ability of activated PC were systematically studied...
