Abstract: 본 발명은 올레핀/파라핀 혼합가스로부터 올레핀을 분리하는 흡착공정에 사용되는 올레핀 선택적 흡착제에 관한 것이다. 올레핀을 선택적으로 흡착하는 흡착제는 표면적이 큰 알루미노실리카겔이나 실리카겔에 질산은을 함침하여 제조하는데 고가의 질산은 대신에 구리에 기반한 복합금속염화물을 사용함으로써 저가의 올레핀 선택성 흡착제를 제조하였다.

Abstract: An olefin selective adsorbent using copper-based complex metal chloride is provided to manufacture an adsorbent showing the quantity of adsorbed olefin and selectivity equal to those of a silver-ion impregnated adsorbent. An olefin selective adsorbent is an adsorbent for absorbing/separating olefin from olefin/paraffin compound. Ferric chloride(FeCl2) of 5 through 29.9 wt% and cupric chloride(CuCl) of 5 through 23.4wt% are dipped into a substrate in which specific surface area is 100 m^2/g or greater. The substrate having large specific surface area is selected from MCM-41, MCM-48, SBA-15, SBA-16 and KIT-6 which are aluminosilica gel, silica gel, alumina and middle-sized porous silica.

Abstract: A method for preparing a silver nitrate-supported adsorbent for olefin/paraffin separation is provided to reduce consumption of silver nitrate that occupies the most price of an adsorbent, thereby lower the price of the adsorbent by treating an aluminosilica gel with a basic solution, thereby removing small pores of the aluminosilica gel that does not take part in the adsorption actually, and a silver nitrate-supported adsorbent for olefin/paraffin separation prepared by the method is provided. As a method for preparing an adsorbent in which silver nitrate(AgNO3) is supported on a pellet type matrix selected from aluminosilica gel, silica gel, and a mixture thereof, a method for preparing a silver nitrate-supported adsorbent for olefin/paraffin separation comprises the steps of: contacting the matrix with a basic solution with a concentration of 0.0125 to 0.0375 M to remove a matrix of micropores with a pore size of 20 Å or less; filtering the matrix in the basic solution, washing the filtered matrix with distilled water, and drying the washed matrix; heating the dried matrix to 300 to 400 deg.C in a nitrogen atmosphere to remove water or other contaminants contained in the matrix; impregnating the matrix that has passed through the heat treatment process in the nitrogen atmosphere with an aqueous silver nitrate solution with a concentration of 0.2 to 1.2 g AgNO3/ml by incipient wetness method, and drying the impregnated matrix in an 100 deg.C air; and heating the dried matrix to a temperature between 100 deg.C and 300 deg.C in an inert gas atmosphere, thereby removing water or impurities contained in silver nitrate during supporting of silver nitrate such that silver nitrate absorbs various olefins well.
