Abstract:
The present invention relates to a method of adsorbing and reducing nitrogen oxides using a mixed metal oxide catalyst, and more particularly, to a method of improving the efficiency of adsorption and desorption of nitrogen oxides using a mixed metal oxide catalyst prepared from a hydrotalcite precursor. According to the invention, NOx and N 2 O, which coexist with oxygen (O 2 ) known to be very difficult to reduce and decompose, are efficiently decomposed by adsorbing and separating NOx and N 2 O from oxygen and then decomposing the adsorbed NOx and N 2 O using a reducing agent.

Abstract:
A process for selective formation of ethanol and/or ethyl acetate from acetic acid by hydrogenating acetic acid in the presence of a Pt/Sn catalyst or a Re/Pd catalyst. The catalyst may further comprise a support modifier to improve selectivity for the desired product.
Abstract:
A process for selective formation of ethanol from acetic acid by hydrogenating acetic acid in the presence of a catalyst comprises a first metal on an acidic support. The acidic support may comprise an acidic support material or may comprise an support having an acidic support modifier. The catalyst may be used alone to produced ethanol via hydrogenation or in combination with another catalyst. In addition, the crude ethanol product is separated to obtain ethanol.
