  • 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.

  • Patent number: 10253273
    Abstract: The present invention relates to a process for obtaining fuel from biomass which comprises the introduction of the catalyst (3) in the base of an cracking section (4), wherein said catalyst (3) at high temperature comes in contact with a gas stream of light hydrocarbons rich in hydrogen (1), wherein the catalyst (3) and hydrocarbon (1) then come in contact with a lignocellulosic liquid stream (2) in the same cracking section (4), creating the reaction mixture (5) that, soon after, comes into contact with the main stream containing the traditional fossil load of a FCC (6) in a second cracking section (7).

  • Patent number: 9216902
    Abstract: The present invention relates to a method for the production of ethene, CO, and hydrogen in a reactor with a circulating fluidized bed with two independent sections, from feedstocks that contain hydrocarbons with at least 11 carbon atoms or from feedstocks with a high oxygen content, using a catalyst in particulate form. The method teaches that in one of the sections of the reactor, in the absence of oxygen, a catalyst containing a dehydrogenation metal promotes the cracking of the said feedstocks, facilitating the subsequent endothermic reactions. In the other section, the coke is burned with air and the heating of the catalyst is controlled, for the adjustment of the appropriate amount of energy that the heated catalyst will convey to the section in which the endothermic reactions take place. The total ethene yield of the process according to the present invention is approximately 20% by weight in relation to the feedstock.
