<p>PURPOSE:To produce an adsorbent for purifying hydrocarbons having high adsorptivity for hydrocarbons, high in desorbing temp. of the hydrocarbons and having heat resistance by constituting the adsorbent of silver, at least one element selected from a group consisting of phosphorus, antimony, bismuth and boron, and a molecular sieves. CONSTITUTION:This adsorbent is composed of the silver, at least one kind of elements selected from the group consisting of the phosphorus, antimony, bismuth and boron and the molecular sieves. In this case, a silicate of crystalline aluminum, a phosphate of the crystalline aluminum, the phosphate or crystalline metallosilicate of a crystalline silicoaluminum are used as the molecular sieves. Moreover, at least one kind selected from a group consisting of MFI, BEA, FAU, FER, ERI and CHA type zeolite is used as the silicate of crystalline aluminum.</p> |
