H_2S$ 제거를 위한 $Li_2ZrO_3$/honeycomb의 반응 특성
[ $H_2S$ ] removal reaction using $Li_2ZrO_3/honeycomb$ has been carried out in a fixed bed reactor for the cleaning of syngas from the waste gasifier. $Li_2ZrO_3$ was synthesised using reagent-grade $Li_3CO_3$ and $ZrO_2$ with suitable amount of ethanol in a 1:1 ratio. And then $Li_2ZrO_3$ were cal...

description | [ $H_2S$ ] removal reaction using $Li_2ZrO_3/honeycomb$ has been carried out in a fixed bed reactor for the cleaning of syngas from the waste gasifier. $Li_2ZrO_3$ was synthesised using reagent-grade $Li_3CO_3$ and $ZrO_2$ with suitable amount of ethanol in a 1:1 ratio. And then $Li_2ZrO_3$ were calcined in air at $850{\sim}1000^{\circ}C$ for 14 h. The optimum condition of $H_2S$ removal reaction is around 20 wt% $Li_2ZrO_3$/honeycomb at 300 mL/min and $700^{\circ}C$. At this condition, removal amount of $H_2S$ was about 0.337 $g^{H_2S}/g^{sorbent}$. Addition of $K_2CO_3$, $Na_2CO_3$, NaCl and LiCl in the $Li_2ZrO_3$ remarkably improves the $H_2S$ removal capacity of modified $Li_2ZrO_3$/honeycomb up to 23%. Analyses of $Li_2ZrO_3/honeycomb$ sorbent by SEM and XRD showed that $Li_2ZrO_3$ was uniformly impregnated into honeycomb up to considerable amounts. Furthermore, the physicochemical properties of the sorbent did not vary much up to $1000^{\circ}C$. 합성가스내의 $H_2S$을 제거하기 위하여 pure 및 modified $Li_2ZrO_3$를 이용하여 고정층 반응기내에서 $H_2S$ 제거실험을 수행하였다. $Li_2ZrO_3$는 $ZrO_2$와 $Li_2ZrO_3$ 순 분말상을 1:1 몰비로 혼합, 에탄올을 첨가하여 교반한 후 $850{\sim}1000^{\circ}C$에서 14시간 소성시켜 제조하였다. 최적 반응조건은 반응온도 $700^{\circ}C$, $Li_2ZrO_3$ 담지량 20 wt%, 유량 300 mL/min으로 확인되었으며, 이 때 $H_2S$ 제거량은 0.337 $g^{H_2S}/g^{sorbent}$으로 나타났다. 또한 첨가제($K_2CO_3$, $Na_2CO_3$, NaCl, LiCl)를 이용, $H_2S$ 제거실험을 실시한 결과 $H_2S$ 흡착능은 최대 23%까지 향상되었다. 또한 honeycomb에 담지된 $Li_2ZrO_3$ 반응물에 대한 SEM 및 XRD 분석결과,40 wt%까지 $Li_2ZrO_3$가 고르게 담지되고, $1000^{\circ}C$의 고온 열처리에도 그 성상이 크게 변하지 않음을 확인하였다. |
