Sobre IBD

A indústria petrolífera está sujeita ao cumprimento de regulamentos governamentais que exigem a produção e utilização de combustíveis mais amigos do ambiente, com menor teor de enxofre. Além disso, o nível de enxofre em combustíveis como a gasolina e o gasóleo deve ser reduzido para 0,01 ppm. Por este motivo, o desenvolvimento de catalisadores com elevada atividade e seletividade para o processo de hidrodessulfurização (HDS) é um dos problemas mais prementes da indústria petrolífera.O objetivo desta investigação foi orientado para o desenvolvimento de catalisadores sólidos mesoporosos como o MCM-48 com incorporação de MoS2 e NiMoSx gerados in situ, por duas vias de síntese: Decomposição de hexacarbonilo de molibdénio mais enxofre durante a impregnação e impregnação incipiente com heptamolibdato de amónio com ou sem Ni mais H2/H2S. Foi também avaliado o comportamento e o desempenho catalítico destes sólidos na reação de desidrodessulfurização do dibenzotiofeno.
