| Abstract: | A new technology to remove thiophene directly from liquid coke-chemical benzene with adsorbent has been investigated. The experimental results have shown that the modified ZSM-5 molecular sieve is the best adsorbent, of which the static adsorptive capacity may attain up to 8.9mg/g. Meanwhile, the effects of operating conditions on the adsorption process have also been studied. Increase in temperature, decrease in the size of adsorbent particles and water content in the adsorbent can improve greatly the adsorptive capacity and rate. This modified ZSM-5 molecular sieve adsorbent can be recovered with water steam at a high temperature. |
