4 Adsorbent Preparations and Applications for C4 Olefin Separation from Mixtures

摘要

PURPOSE: Provided are a method for producing stable solid granular adsorbent with cylinder or sphere feature used for C4 olefin separation from mixtures and an application of the same adsorbent. CONSTITUTION: The method comprises the steps of dissolving silver compound such as caustic silver, lipid silver oxide, halogenation silver, silver oxide and a mixture thereof, into a solvent; mixing the silver compound solution with clay supports; drying the mixture at temperature between 100-200C for 3 hours or more; and heat treating the dried mixture at 30-350C for 3 hours or more, wherein feature of the clay support may be powder, granular, cylinder, or sphere, and contains 60-85 wt% of SiO2, 4-25 wt% of Al2O3, 2-10 wt% of Fe2O3, 3wt% of CaO, 7wt% of MgO, 3wt% of Na2O and 3wt% of K2O.
