The present invention relates to a process for the production of bio-oil-based renewable streams for composing a diesel or aviation kerosene (AVK) pool by combining the technologies of hydroprocessing esters and fatty acids (HEFA) and thermochemical conversion of lignocellulosic biomass for generating bio-oil. The integration of conventional raw material from the HEFA pathway with a bio-oil fraction has the advantages of the use of a stream originating from the conversion of lignocellulosic material, which is widely available on the market, and also the production of a renewable stream containing aromatics in its composition.

Process for generating renewable streams from bio-oil and use thereof for the production of renewable fuels

The present invention addresses to a hydrothermal liquefaction process capable of generating a liquid stream, rich in renewable molecules, with lower oxygen content, lower percentage of water and lower acidity compared to other products of thermochemical processes of biomass conversion. In order to effectively carry out this process, a catalyst was developed, obtained from the calcination of castor bean hull, to be used in the field of biofuels in order to provide an environmentally friendly alternative for the production of fuels.

The present invention refers to the processing of a 100% renewable load in FCC units, wherein the load comprises triglycerides of vegetable and animal source, free fatty acids, fatty acid esters, ketones, alcohols and long-chain aldehydes, using catalyst and appropriate operating conditions in order to obtain 100% renewable products with a high content of aromatic compounds, in the range of naphtha, kerosene, diesel and heavy gas oil. The product thus obtained complies with all the properties of the ASTM D1655 standard, even for contents of up to 10% renewable content. In addition, there is no need to reduce the freezing point of the fossil QAV for the introduction of the renewable component, with no impact on the yield and economy of the process.

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 C-Chydrocarbons 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. The conversion section is selected from catalytic hydrocracking unit, thermal cracking, fluidized-bed catalytic cracking, visbreaking, delayed coking and catalytic reforming.

Additives for mixing into the base catalyst inventory of the fluid catalytic cracking (FCC) process units, so as to achieve a high selectivity of light olefins (ethylene and propylene), are described. Such additives comprise an FER zeolite and an MFI zeolite, the MFI zeolite preferably being zeolite ZSM-5. The mixture of the additive in a concentration greater than 2% w/w relative to the base catalyst of an FCC unit allows greater selectivity for light olefins, propylene and ethylene, while maintaining catalytic activity.

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.

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.

The present invention relates to a system for the separation of suspensions of spent catalysts and hydrocarbons formed in an FCC unit with multiple ascending flow reaction tubes, comprising interconnections between each of the ascending flow reaction tubes and the separator vessel, each interconnection also comprises two sections. The outside sections of the separator vessel are inclined and are connected to a single vertical section, which penetrates into the interior of the separator vessel, and which has at its lower end an open device for draining the spent catalyst from the suspensions separated in this sector. In the same vertical section, at the end of its internal part at the separator vessel, a series of two sets of cyclones are installed, the first set containing cyclones without sealing legs, and the second set containing conventional cyclones of the first stage. The present invention also relates to a process for the separation of suspensions of spent catalysts and hydrocarbons using the said separation system.

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.

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.

A process for reducing the naphthenic acidity of petroleum oils or their fractions is described, said process comprising providing a hydrocarbon feedhaving between 0.1 and 99 wt % of emulsified/dispersed water in oil, said feed containing salts and a content of naphthenic acids measured as TAN between 0.1 and 10 mg KOH/g oil; directing the said petroleum oil feed and emulsified/dispersed water towards an energy emitter device in the microwave range and submitting said feedin liquid phase, under pressure between 0.7 and 4.5 MPa at temperatures between 50&#xb0; C. and 350&#xb0; C. to the microwave radiation, applied in the range of 1 mm to 30 cm to said feed so that the presence of salts, the applied temperature and the high dielectric constant of the water droplets make that the heat is absorbed on the spot by the water and heat said water preferentially to the oil, while the naphthenic compounds at the interface between the droplets and the oil catch said heat; effecting the decomposition of the carboxylic acids responsible for the naphthenic acidity in the petroleum feed at temperatures around 320&#xb0; C. and generating CO; separating with the aid of any known deviceany gas phase generated, water and oil; and recovering the hydrocarbon oil streamhaving a reduced content in naphthenic acids. The process is designed to be applied to the reduction of naphthenic acids in feeds of petroleum oils and their fractions in the oil production step, in refineries or any industrial installation.
