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.

Process for producing crude bio-oil from biomass with a high moisture content and catalyst for hydrothermal liquefaction of streams of biomass with a high moisture content

The present invention concerns a catalyst and pre-treatment process for acidic charges consisting of sulfated zirconia and cerium for the production of biofuels, characterized in that the catalyst has greater activity and resistance to deactivation with acidic charges.

Process of obtaining a catalyst, catalyst and pre-treatment process of acidic raw materials

The present invention concerns a process for producing biodiesel with bifunctional heterogeneous acidic catalysts from acidic raw materials, such as fatty acids and mixtures of fatty acids with triglycerides.

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.

The present invention describes a process for purifying biodiesel without using a filter aid, in which purification of the biodiesel takes place by a sequence of washing operations after the reaction section, with stirring that is sufficiently vigorous to assist in the transformation of the molecules of esterified steryl glycosides, in order to convert them to a chemical form that can be removed by the process.
