Síntese e caracterização de catalisadores zeolíticos do tipo ZSM-12 utilizando diferentes fontes de alumíniona indústria do petróleo
Abstract
Neste trabalho o objetivo principal foi sintetizar zeólitas do tipo ZSM-12 partindo de diferentes fontes de alumínio, utilizando o método hidrotérmico e caracterizar os catalisadores sintetizados por difração de raios-X, análise térmica e espectroscopia de absorção na região do infravermelho.
Os difratogramas de raios-X evidenciaram a formação de zeólita da família pentasil cristalinas. As curvas termogravimétricas e os espectros FTIR foram utilizados para monitorar a remoção do direcionador e para monitorar a manutenção da estrutura zeolítica.
