  • Process of coprocessing a lignocellulosic liquid stream and an intermediate fossil stream in an oil refining process and a process for producing fuel from a deasphalted oil stream
    Patent number: 11505753
    Abstract: The present invention describes the coprocessing of a lignocellulosic liquid stream and an intermediate fossil stream in the oil refining process comprising the steps of (a) contacting said intermediate fossil stream and said lignocellulosic liquid stream with a stream of solvent of C3-C10 hydrocarbons in an extraction section, obtaining a stream of extract with solvent and a stream of raffinate with solvent; and (b) sending said stream of extract with solvent to a separation section, obtaining a deasphalted oil stream comprising solvent-free carbon of renewable origin and a stream of recovered solvent. The present invention further relates to a process for producing fuels from the deasphalted oil stream comprising carbon of renewable origin, wherein the process comprises sending the deasphalted oil stream to a conversion section of an oil refinery.

  • Process for reducing the naphthenic acidity of petroleum oils
    Patent number: 7504023
    Abstract: A process for reducing the naphthenic acidity of petroleum oils, or their liquid fractions, is described, the process comprising a thermal treatment of the petroleum oils, or their liquid fractions, in the presence of an adsorbent the surface of which is covered by high molecular weight carbon compounds. Preferred adsorbents are the spent or coked FCC catalysts.
