Abstract

ROJAS, HUGO et al. CROTONALDEHYDE HYDROGENATION OVER Ir/Tio2-siO2 CATALYSTS. Dyna rev.fac.nac.minas [online]. 2009, vol.76, n.157, pp.173-180. ISSN 0012-7353.

Liquid phase crotonaldehyde hydrogenation over Ir/TiO2-SiO2 catalysts was studied; this aldehyde is highly pollutant comes from cigarette smoke, exhaust from gasoline and diesel engines and the burning of wood [1]. The main objective of this research was unsaturated alcohol (crotyl alcohol) obtention. This study showed that an increase in TiO2 content and high temperature reduction in catalysts produce high selectivity to crotyl alcohol, high activity, and an increase in conversion levels. This behavior is due to SMSI (Strong Metal Support Interaction) effect, at high temperatures in partially reducible oxides.

Keywords : Crotonaldehyde; catalytic hydrogenation; unsaturated alcohol; mixed support.
