    Abstract: The invention relates to a method for producing formic acid by hydrogenation of carbon dioxide in the presence of a catalyst which contains an element of the 8th, 9th or 10th group of the periodic system, a tertiary amine and a polar solvent, at a pressure of 0.2 to 30 MPa abs and a temperature of 20 to 200°C, thereby producing two liquid phases, and separation of the two liquid phases. The liquid phase (B) enriched by the tertiary amine is returned to the hydrogenation reactor and the formic acid/amine addition product from the liquid phase (A) enriched by the formic acid/amine addition product and the polar solvent is thermally separated into free formic acid and free tertiary amine in a distillation unit and the tertiary amine released during separation and the polar solvent are returned to the hydrogenation reactor.

    Abstract: PROCESS FOR PREPARING FORMIC ACID BY HYDROGENATION OF CARBON DIOXIDE IN THE PRESENCE OF A CATALYST COMPRISING AN ELEMENT OF GROUP 8, 9 OR 10 OF THE PERIODIC TABLE, A TERTIARY AMINE AND A POLAR SOLVENT AT A PRESSURE OF FROM 0.2 TO 30 MPA ABS AND A TEMPERATURE OF FROM 20 TO 200° C. TO FORM TWO LIQUID PHASES, SEPARATION OF THE TWO LIQUID PHASES, WHEREIN THE LIQUID PHASE (B) ENRICHED WITH THE TERTIARY AMINE IS RECIRCULATED TO THE HYDROGENATION REACTOR (A) AND THE FORMIC ACID/AMINE ADDUCT FROM THE LIQUID PHASE (A) ENRICHED WITH THE FORMIC ACID/AMINE ADDUCT AND THE POLAR SOLVENT IS THERMALLY DISSOCIATED INTO FREE FORMIC ACID AND FREE TERTIARY AMINE IN A DISTILLATION UNIT (C) AND THE TERTIARY AMINE LIBERATED IN THE DISSOCIATION AND THE POLAR SOLVENT ARE RECIRCULATED TO THE HYDROGENATION REACTOR (A).

    Abstract: "processo para preparar ácido fórmico". é proposto um processo para´preparar ácido fórmico através da reação de dióxido de carbono (1) com hidrogênio (2) em um reator de hidrogenação (i) na presença de um catalisador que compreende um elemento dos grupos 8,9 ou 10 da tabela periódica, de uma amina terciária contendo pelo menos 12 átomos de carbono por molécula e um solvente polar que compreende um ou mais monoaçlcoóis selecionados de metanol, etanol, propanóis e butanóis, e água, para formar adutos de ácido fórmico/amina como intermediários, que são subsequentemente clivados de maneira térmica, com processamento das saídas (3) do reator de hidrogenação (i) em várias etapas de processo, uma corrente (13) compreendendo amina terciária do processamento sendo usada como solvente seletivo para o catalisador.
