Abstract

A INVENÇÃO DIZ RESPEITO A UM PROCESSO DE PREPARAÇÃO DE GÁS DE SÍNTESE POR ELETRÓLISE ALCALINA DE ÁGUA COM RECURSO A UMA FONTE DE CARBONO, NOMEADAMENTE BIOMASSA LIQUEFEITA (2), COM OS PASSOS: I) ENTRADA DO ELETRÓLITO (1) NO ELETROLISADOR (5) A PARTIR DO PRIMEIRO DEPÓSITO (3), II) RECOLHA DA MISTURA DE ELETRÓLITO E GÁS DE SÍNTESE (7) NO SEGUNDO DEPÓSITO (4), III) RETORNO DO ELETRÓLITO RECICLADO AO ELETROLISADOR (5) PELA BOMBA (12), QUE PERMITE UMA PURGA (13), IV) RECOLHA DO GÁS DE SÍNTESE (11) NO DEPÓSITO (10). A INVENÇÃO TAMBÉM SE REFERE A UMA INSTALAÇÃO COMPREENDENDO O PRIMEIRO DEPÓSITO (3), O ELETROLISADOR (5) COM UMA FONTE DE ALIMENTAÇÃO DE CORRENTE CONTÍNUA (14), O SEGUNDO DEPÓSITO (4), O TRANSDUTOR DE PRESSÃO (8) E O DEPÓSITO (10), EM QUE O GÁS DE SÍNTESE (6) SEPARADO DO SEGUNDO DEPÓSITO (4) PASSA PELO ABSORVEDOR COM PENEIRO MOLECULAR (9) ANTES DO RECOLHIMENTO NO DEPÓSITO (10).The invention relates to a process for preparing synthesis gas by alkaline water electrolysis using a carbon source, namely liquefied biomass (2), with the following steps: I) Entry of the electrolyte (1) into the electrolyzer (5) from the first tank (3), II) Collection of the mixture of electrolyte and synthesis gas (7) in the second tank (4), III) Return of the recycled electrolyte to the electrolyzer (5) by the pump (12), which allows a purge (13), IV) Collection of the synthesis gas (11) in the tank (10). The invention also relates to an installation comprising the first tank (3), the electrolyzer (5) with a DC power supply (14), the second tank (4), the pressure transducer (8) and the tank (10), wherein the synthesis gas (6) separated from the second tank (4) passes through the absorber with molecular sieve (9) before collection in the tank (10).
