Abstract: The present invention relates to a process for the conversion of plant oils, animal fats, waste food oils and carboxylic acids into renewable liquid fuels, such as bio-naphtha, bioQAV and renewable diesel, for use in combination with fossil fuels. The process is composed of two steps: hydrotreatment and hydrocracking. The effluent from the hydrotreatment step contains aromatics, olefins and compounds resulting from the polymerization of esters and acids. This is due to the use of partially reduced catalysts without the injection of a sulfiding agent and allows for the production of bioQAV of suitable quality for use in combination with fossil kerosene. Concurrently, the process generates, in addition to products in the distillation range of naphtha, kerosene and diesel, high molecular weight linear paraffins (up to 40 carbon atoms).

Abstract: The present invention relates to a process for converting vegetable oils, animal fats, residual edible oils and carboxylic acids into renewable liquid fuels, such as bionaphtha, bioJET-A1 and renewable diesel, for use in a mixture with fossil fuels. The process consists of two steps: hydrotreating and hydrocracking. The effluent from the hydrotreatment step presents aromatics, olefins and compounds resulting from the polymerization of esters and acids in its composition. This fact occurs due to the use of partially reduced catalysts and without injection of sulfide agent and allows obtaining a bioJET-A1 with adequate quality for use in a mixture with fossil kerosene. At the same time, the process generates, in addition to products in the distillation range of naphtha, kerosene and diesel, high molecular weight linear paraffins (with up to 40 carbon atoms).

Abstract: 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.

Abstract: 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.

Abstract: The present invention relates to a catalyst for selective hydrodesulphurization of cracked naphtha streams in the form of an extrudate, which comprises a support based on an inorganic oxide and an outer layer bound to the support, wherein the outer layer comprises desulphurization metals dispersed therein forming a crown, the desulphurization metals being cobalt and molybdenum. The present invention also relates to the preparation of said catalyst by the incipient wetness impregnation method and to the process for selective hydrodesulphurization of cracked naphtha employing same.

Abstract: The present invention describes a method for refining highly polyaromatic and nitrogenated charges, such as LCO streams, comprising hydrotreating (HDT) as the first reaction stage, followed by the intermediate separation of gases generated in the HDT section, then by a second reaction stage consisting in moderate hydroconversion/hydrocracking and in a rectifying and/or fractionating section, thus allowing more flexible production of fuels. In the rectification mode, the claimed method yields a diesel oil fraction with higher cetane content, reduced density and volumetric yield increase of at least 111% relative to the process charge, thus minimising yield losses through naphtha overcracking and contributing to the optimisation of the required hydrogen consumption. In the fractionating mode, different cuts and their compositions can be produced, such as naphtha, kerosene and diesel.

Abstract: A co-processing combining a first selective catalytic bed consisting of only one metal element selected from group VIB metals and of at least one conventional hydrotreating bimetallic catalytic bed. The co-processing provides control of the hydroconversion reactions of the triglycerides and/or fatty acids of biomass oil diluted in a refinery stream of petroleum hydrocarbons and minimizes the generation of gaseous products that are undesirable to the process, while maintaining the levels of unsaturated hydrocarbons hydrogenation and of heteroatomic contaminants removal from the refinery stream of petroleum hydrocarbons. The co-processing selectively providing n-paraffins of even number of carbon atoms, generated from the biomass oil, which are incorporated in a hydrotreated liquid product in petroleum refining HDT units.

Abstract: The invention relates to the field of methods used for the transesterification of oils and fats in order to produce diesel oil. The invention provides a novel method for the production of diesel oil by transesterifying fatty acid esters present in vegetable oils and fats, using a novel catalyst consisting of the oxide of a group V metal and having the formula X2O5, such as niobium pentoxide (Nb2O5). Unlike in the methods used traditionally according to the prior art, the oils are converted here into high-purity products, including glycerol, in yields of the order of 100%, while using significantly less catalyst for a quantity of oil processed, when e.g. soya-bean oil, cotton-seed oil and canola oil are processed by the method according to the invention.
