Abstract

The purpose of this study is to investigate the optimal condition for the hydrogen-rich gas production and the CO removal by reforming of gliding arc plasma reforming system using biogas. The parametric screening studies were carried out according to changes of steam feed amount, catalyst bed temperature in water gas reactor and catalyst bed temperature, input air flow rate in preferential oxidation reactor. The standard condition is as follows. The steam/carbon ratio, catalyst bed temperature, total gas flow rate, input electric power and biogas composition rate ($CH_4$ : $CO_2$) were fixed 3, $700^{\circ}C$, 16 L/min, 2.4 kW and 6 : 4, respectively. The results are as follow, HTS optimum operating conditions were S/C ratio of 3 and reactor temperature of $500^{\circ}C$. LTS were S/C ratio of 2.9 and temperature of $300^{\circ}C$. Also, PROX I optimum conditions were input air flow rate of 300 mL/min and reactor temperature of $190^{\circ}C$. PROX II were 200 mL/min and $190^{\circ}C$ respectively. After having passed through each reactor, the results were as follows: 55% of $H_{2}$ yield, 0% of CO selectivity, 99% of $CH_4$ conversion rate, 27% of $CO_2$ conversion rate, respectively.

본 연구의 목적은 바이오가스를 이용하여 고농도 수소 생산과 CO 제거가 가능한 글라이딩아크 플라즈마 개질 시스템의 개발이다. 이를 위하여 수성가스 전이반응기는 수증기 주입량 변화,촉매층 온도 변화에 대하여, 선택적 산화반응기는 촉매층 온도변화, 공기주입량에 대하여 실험을 진행하였다. 기준조건은 S/C 비 3, 촉매층 온도 $700^{\circ}C$, 전체가스량 16 L/min, 입력전력 2.4 kW, 바이오가스 구성비($CH_4$ : $CO_2$ ) 6 : 4이다. 이때의 실험결과는 HTS의 최적조건은 S/C비 3, 반응온도 $500^{\circ}C$, LTS의 최적조건은 S/C 비 2.9, 반응온도 $300^{\circ}C$이다. 또한 PROX I단의 최적조건은 각각 공기유입량 300 mL/min, $190^{\circ}C$, PROX II단의 최적조건은 공기유입량 200 mL/min, $190^{\circ}C$을 나타내었다. 반응기를 모두 지난 후의 합성가스는 $H_2$ 수율 55%, $CH_4$ 전환율 97%, $CO_2$ 전환율 97%, CO 선택도는 0%로 바이오가스를 개질하여 생성된 합성가스는 높은 수율을 나타내며, CO 선택도는 0%를 나타내었다.
