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).

Catalysts and selective process for the production of renewable aviation fuels and biofuel produced

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.

Process for production of aviation kerosene from a stream rich in aromatic compounds of renewable source

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).

Selective process and catalysts for the production of renewable fuels and distillates of high molecular weight

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.

Process for hydrotreating biomass oil diluted in a refinery stream of petroleum hydrocarbons

A process for the selective hydrodesulfurization of a naphtha containing olefins and organosulfur compounds is disclosed, which minimizes the hydrogenation of the olefins and results in a product with a low sulfur content. The process involves a two-stage hydrodesulfurization with HS removed from the first stage effluent. A flow of hydrogen and at least one added non-reactive compound is fed into the first stage, wherein the Hmolar fraction ranges from 0.2 to 1.0, and with HS at the reactor intake limited to a maximum of 0.1% by volume. The second stage involves a feedstream of hydrogen and at least one added non-reactive compound, wherein the Hmolar fraction ranges from 0.2 to 0.7 and with HS at the reactor intake limited to a maximum of 0.05% by volume.
