Abstract:
1. A process for making a surface-modified adsorbent, said process comprising: (i) providing at least one adsorbent in particulate form and at least one non-volatile organic compound to a vessel; (ii) adjusting temperature and/or pressure to provide supercritical conditions in said vessel for a supercritical fluid; and (iii) introducing the supercritical fluid into the vessel, such that the supercritical fluid dissolves the non-volatile organic compound, and wherein the supercritical fluid with the dissolved non-volatile organic compound impregnates the adsorbent to form surface-modified adsorbent particles, wherein the adsorbent comprises activated carbon, and wherein the non-volatile organic compound is selected from the group consisting of: squalene, squalane, phytol, and mixtures thereof.
