Emprego da Pilarização na Argila Regional do Tipo Montmorilonita na Reação de Isomerizacão do Buteno-1/ Use of Pillarization in Regional Montmorillonite Clay in the Butene-1 Isomerization Reaction
Keywords:Montmorillonite, Buthene-1 isomerization, pillarization
The regional montmorillonite clay from Santo Amaro da Purification, the region of Recôncavo Baiano, was subjected to chemical treatment for the destruction of organic matter, after which the pillarization technique was applied using the hydroxyacetatoferro precursor (III) in order to generate a isomerization of butane 1. The solids were characterized by conventional techniques such as: DRX, TG/DTA, specific surface area measurement, MEV and RTP, in order to evaluate their importance as a clay-resercible that can be restructured chemical composition and crystallographic.. The results indicated that the pillarization resulted in the formation of thermally stable iron oxide. The Brönsted acid sites, detected by absorbed pyridine FTIR, were active in the geometric isomerization of butenes, with 22% selectivity to the cis isomer and 47% to the trans isomer.
