  • 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.

  • Patent number: 8513476
    Abstract: The process combines hydroconversion and catalytic cracking starting from a feed containing triglycerides, at concentrations of fatty acids above 85%, which maximizes the yields of light olefins, chiefly ethylene and propylene, while reducing the yield of gasoline, with conversion greater than 80 wt. %.

  • Patent number: 8231777
    Abstract: The present invention comprises a thermocatalytic cracking process for the production of diesel oil from a charge of vegetable origin made from seeds of oleaginous plants in refineries possessing at least two FCC reactors. At least one of such reactors processes heavy gas oil or residue under conventional conditions while at least one of such reactors processes the charge of vegetable origin made from seeds of oleaginous plants under conditions suitable, for production of diesel oil. Said process employs the same catalyst utilized in the fluid catalytic cracking process which, simultaneously, processes a conventional charge. The diesel, or biodiesel, oil produced by means of said process is of superior quality having a cetane number exceeding 40 given that the cracking reactions occur at low temperatures and the products obtained are less oxidized and consequently purer than products obtained by means of existing technology.

  • Patent number: 7867378
    Abstract: A method is described for co-processing of ethanol and hydrocarbons from petroleum refining, which are introduced separately in two reaction zones of a reactor of a fluidized catalytic cracking unit. The process combines conversion of ethanol into ethene and conversion of hydrocarbons into other lighter hydrocarbon fractions, to produce ethene in quantities of 15 to 90 wt % in the fuel gas fraction obtained during the process.

  • Patent number: 7540952
    Abstract: The present invention relates to a thermo catalytic process to produce diesel oil from vegetable oils, in refineries which have two or more Catalytic Cracking (FCC) reactors. At least one reactor processes heavy petroleum or residue in conventional operation conditions while at least one reactor processes vegetable oils in proper operation conditions to produce diesel oil. This process employs the same catalyst employed in the FCC process, which processes conventional feedstocks simultaneously. This process transforms high heat content raw materials into fuel hydrocarbons. It may improve efficiency for the obtainment of highly pure products and may not yield glycerin, one by-product of the transesterification process. The diesel oil produced by said process may have superior qualities and/or a cetane number higher than 40. Once cracking conditions occur at lower temperatures, it may form a less oxidized product, which is consequently purer than those obtained by existent technology.
