Abstract: Disclosed is a catalyst based on synthetic silica, in a heterogeneous catalysis method, to promote the effective conversion of residual glycerin, resulting from the production of biodiesel, into formic acid with high selectivity and stability, in a continuous flow reaction. The conversion of residual glycerin occurs by homogeneous catalysis, by the action of components remaining from the synthesis of biodiesel, with the formation of major compounds, such as formic acid, cyclic ethers and diglycerol, in continuous flow and reflow reactions. The reaction can also be carried out by adding sodium salts in the homogeneous catalytic conversion process of commercial glycerin. The process values the residual glycerin, without the need for purification before its transformation into products with high added value, but of renewable origin, adding more interest and potential.

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.

Abstract: This invention belongs to the field of catalysts for the transesterification of triglycerides, for the production of fatty acid glycerin and esters. This invention describes preparatory methods using solid catalysts and the formulation of these catalysts for the production of fatty acid esters, glycerin, and specifically, biodiesel through the heterogeneous transesterification reaction of triglycerides present in vegetable oils and fats, like soy, cotton seed, canola, castor, peanut oils and animal fat. The solid catalysts of this invention are sufficiently magnetic to use in the production of biodiesel from vegetable oils and fats, not only because they work in a similar fashion as state of the art catalysts, but also because of the low cost of the raw materials used in its production. The invention even describes the composition obtained by using the catalysts, in which the purity of the products, such as biodiesel and glycerin is greater than 96.5%.

Abstract: A process is described for production of Bio-Oil by delayed coking with modified feedstock, in which the feed of the conventional coke unit envisages, in addition to the usual fresh feed of hydrocarbon (vacuum residue, atmospheric residue etc.), the feeding of a biomass for coprocessing. Said biomass can be selected from the group comprising sugar cane straw, sugar cane bagasse, castor seed cake, coconut shells, rice husks, raw soya, castor seed, canola, oil palm, and cottonseed oils, and oils and fats of animal origin, which can be used separately, or as mixtures thereof in any proportions.
