Abstract

"MEMBRANA DE MATRIZ MISTA, MéTODO DE PREPARAR A MESMA, E, PROCESSO PARA SEPARAR DOIS COMPONENTES GASOSOS". Uma membrana de matriz mista é proporcionada que compreende um polímero orgânico de fase contínua e peneiras moleculares contendo alumina de poro pequeno dispersas no mesmo. As peneiras moleculares possuem uma razão molar de sílica-para-alumina menor do que 1,0, com maior preferência, menor do que 0,3, e mais preferivelmente menor do que 0,1. Em alguns casos, as peneiras moleculares não possuem quantidades apreciáveis de sílica. Composições exemplares incluem aluminofosfatos (AIPO) e sílicoaluminofosfatos (SAPO). Quando estas peneiras moleculares são apropriadamente interespaçadas conr um polímero de fase contínua, a membrana exibirá um efeito de membrana de matriz mista, i.e., um aumento de seletividade de pelo menos 10% relativo a uma membrana pura não contendo peneiras moleculares. As peneiras moleculares possuem poros com um diâmetro livre cristalográfico menor mais elevado de 0,40 nm ou menor. As peneiras moleculares podem ser selecionadas do grupo possuindo tipos de estrutura IZA incluindo AEI, CHA, ERI, LEV, AFX, AFT, e GIS. Exemplos de peneiras moleculares preferidas incluem: AIPO-18, SAPO-18, AIPO-34, SAPO-34, SAPO-44, SAPO-47, AIPO-17, CVX-7, SAPO-35, SAPO-56, AIPO-52 e SAPO-34. Finalmente, métodos para preparar e usar tais membranas de matriz mista para separar gases de uma mistura contendo dois ou mais gases também são descritos.
