Abstract: The present invention relates to a method for optimization and recovery of second-generation sugar diluted stream, comprising pretreatment, enzymatic hydrolysis and mainly washing the residual solid from the enzymatic hydrolysis, which allows the increase of sugar recovery. The use of this sugar diluted stream is crucial for process integration, may have different possibilities of use, for example, can be applied in the mechanical refining step, microorganisms propagation, enzyme production, fermentation, enzymatic hydrolysis, including combination of uses.

Abstract: The present invention addresses to an optimized process for the production of ethanol from energy cane, by the integration of first-generation (1G) and second-generation (2G) technologies, which presents the advantages of reducing energy and water consumption. More specifically, the secondary juice from the second set of three rolls of mills of the conventional process (1G) is used for dilution, in the enzymatic hydrolysis step, in the cellulosic ethanol production process (2G).

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 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.

Abstract: 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 C3-C10 hydrocarbons 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.
