摘要: A process that allows the extraction of compounds of nutraceutical interest (specifically omega-3 and carotenoids) from microalgae and their separation through the use of CO2 in supercritical conditions (and when necessary a co-solvent), at the same time, wherein the removal of an unwanted component (tripalmitin) from the lipid extract, always by using supercritical CO2 in a fractional extraction, is advantageously carried out using its different extraction kinetics respect to the component present in the lipid phase.

摘要: An autocatalytic process for producing fatty acids from fatty acids methyl esters with an overall conversion higher than 90% which includes multiple hydrolysis reactions in series, in purely thermal conditions, with intermediate separation of phases after each hydrolysis reaction and before the subsequent, operating in excess of water, in order to separate the methanol/water phases from the equilibrium phase and favor the formation of fatty acids product.

摘要: A nano-catalyst which is usable in processes of vegetable oil hydrogenation for producing bio-lubricants or biodegradable plastics for producing copolymers, characterized in that it consists of an active phase composed of nickel, palladium and ruthenium, dispersed on a support including graphene layers less than 1 micron, the outer surface of which is covered with surfactant chains, and having a high activity and a very high selectivity for the cis-configuration of the 9-octadecenoic acid (cis-oleic acid).

摘要: Disclosed is a catalyst suitable for the catalytic oxidative cracking of a H2S-containing gas stream. The catalyst comprises at least one or more active metals selected from the group consisting of iron, cobalt, and nickel, supported by a carrier comprising ceria and alumina. The active metal is preferably in the form of its sulphide. Also disclosed is a method for the production of hydrogen from a H2S-containing gas stream, comprising subjecting the gas stream to catalytic oxidative cracking so as to form H2 and S2, using a catalyst in accordance with any one of the composition claims.

摘要: Process for the conversion of plastics to olefins comprising the following steps: A) gasification of the plastics to synthesis gas by reaction of the plastics with pure oxygen; B) catalytic conversion of the synthesis gas produced in stage A) to methane in at least three successive stages, in each of which hydrogen is added; C) catalytic conversion of the methane produced in stage B) into olefins by the oxidative coupling reaction of methane; and D) separation of the olefins produced in stage C) from other compounds present in the reaction mixture of said stage C).
