| 摘要 |
The present invention relates to an improved cyclic adsorption process for recovering condensible components from a gas stream wherein the condensible components are removed from the adsorbent by contacting it with a heated regeneration gas stream and after being recovered are separated into liquid fractions of differing molecular weights. By the present invention, the adsorbent is periodically washed with quantities of one or more of the recovered liquid fractions so that components adsorbed thereon which are not readily removed by the heated regeneration gas stream are removed by the solvent action of the liquid fraction or fractions thereby preventing the build-up of said components on said adsorbent and the resultant decrease in absorption capacity.
