| 摘要 |
<p>The present invention provides a process for the recovery of aniline or an aniline derivative from a fluid said process comprising: (i) contacting a feed stream having an aniline or aniline derivative concentration of C1, with an adsorbent material at temperature, T1, such that aniline or aniline derivative is adsorbed by the adsorbent material; (ii) subjecting the adsorbent material to a temperature, T2, which is higher than T1, such that adsorbed aniline or aniline derivative is released to yield an aniline-rich or aniline derivative-rich exit stream having an aniline or aniline derivative concentration of C2, where C2 is greater than C1; and (iii) retaining the aniline-rich or aniline derivative-rich exit stream for recycling or further processing.</p> |
