Abstract: The present invention discloses an adsorbent for selective adsorption of unsaturated hydrocarbons from its mixture with saturated hydrocarbons, carbon dioxide, carbon monoxide, permanent gases or mixture thereof comprising of silver or copper compound 1 to 70 wt % and substrate 30 to 99%. The invention also discloses a method for the manufacture of an adsorbent for use in selective adsorption of unsaturated hydrocarbons or mixtures thereof from a mixed gas, which comprises impregnating or dispersing a silver (I) or copper (I) compound on a mesoporous substrate or support to form a composite material and subjecting said composite material to heat treatment. In another important aspect, the present invention also relates to a process for separating ethylene and/or propylene from gas mixtures containing them by passing a stream of said gas mixture through a mass of said adsorbent at a temperature from 0null C. to 170null C. and a pressure from 0.1 to 100 atmospheres and releasing the adsorbed ethylene and/or propylene by lowering pressure and/or increasing temperature.

Abstract translation: 本发明公开了一种吸附剂，用于从其与饱和烃，二氧化碳，一氧化碳，永久性气体或其混合物中的不饱和烃选择性吸附1〜70重量％的银或铜化合物，底物为30〜99％。 本发明还公开了一种制备吸附剂的方法，所述吸附剂用于从混合气体中选择性吸附不饱和烃或其混合物，其包括将银（I）或铜（I）化合物浸渍或分散在介孔基材或载体上 以形成复合材料并对所述复合材料进行热处理。 在另一个重要方面，本发明还涉及一种从含有它们的气体混合物中分离乙烯和/或丙烯的方法，该方法是将所述气体混合物流通过一批所述吸附剂在0℃至170℃ 并且压力为0.1至100个大气压，并通过降低压力和/或升高温度释放吸附的乙烯和/或丙烯。
