Use of an adsorbent for the removal of liquid, gaseous and/or dissolved constituents from a process stream
First Claim
1. A process for the removal of liquid, gaseous and/or dissolved constituents from a process stream, comprising contacting the process stream with an adsorbent comprising a first porous material and which has been incorporated into a second porous material, and wherein at least 30 vol. % of the pores of the first and second porous materials of which is filled with an extraction liquid including paraffin oil and a dialkyl phthalate with an alkyl group having eight to sixteen carbon atoms, and where the affinity between the adsorbent and the constituents to be removed exceeds the affinity between said constituents and the extraction liquid.

Abstract
A process for the removal of liquid, gaseous and/or dissolved constituents from a process stream. The process stream is contacted with an adsorbent comprising a first porous material which has been incorporated into a second porous material at least 30 vol. % of the pores of the first and second porous materials of which are filled with an extraction liquid. The affinity between the adsorbent and the constituents to be removed exceeds the affinity between the constituents and the extraction liquid.
