Abstract

Se describe un proceso para adsorber nitrógeno selectivamente de otro gas componente menos fuertemente adsorbido (preferiblemente oxigeno), que comprende poner en contacto la mezcla de gases en una zona de adsorción, con un adsorbente que comprende un tamiz molecular de poro grande, que contiene al menos, un sitio octaédrico que comprende titanio y por lo menos silicio, como sitio tetraédrico. El proceso es particularmente útil en la separación de aire, utilizando ETS-10 como adsorbente.A process for selectively adsorbing nitrogen from another less strongly adsorbed component gas (preferably oxygen) is described, which comprises contacting the gas mixture in an adsorption zone with an adsorbent comprising a large pore molecular sieve, containing least, an octahedral site comprising titanium and at least silicon, as a tetrahedral site. The process is particularly useful in air separation, using ETS-10 as an adsorbent.
