  • Patent number: 11939535
    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).

  • Publication number: 20240024855
    Abstract: The present invention deals with a catalyst for converting CO by the reaction of water gas shift at high temperature, free of chromium and iron, consisting of alumina promoted by potassium and zinc oxide. The catalyst prepared in this way maintains a high CO conversion activity, not having the environmental or operating limitations with low excess steam in the process, which exist for state of the art catalysts. Such a catalyst is used in the process of producing hydrogen or synthesis gas by steam reforming hydrocarbons, allowing the use of low steam/carbon ratios in the process, presenting high activity and stability to thermal deactivation and lower environmental restrictions on production, storage, use and disposal, than catalysts used industrially based on iron, chromium and copper oxides.

  • Publication number: 20230332057
    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).

  • Patent number: 11247202
    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.
