Abstract

Oxy gasification was performed for the production of high quality syngas from the waste. $CO_2$ was used as reactant with $O_2$ for $CO_2$ gasification and greenhouse gas reduction. Therefore, gasification was performed at high temperature of $1000-1400^{\circ}C$. RPF was gasified in the thermobalance and 0.5 ton/day pilot plant gasifier. Weight variation with temperature and CO production by Boudouard reaction were studied for $CO_2$ gasification of RPF in thermobalance reactor. Syngas of high $H_2$ concentration was produced from oxy gasification in 0.5 ton/day pilot system, which showed appropriate $H_2$/CO ratio for the production of transport fuel and chemical products.

저급 에너지인 폐기물로부터 고부가 합성가스를 생산하고 온실가스 저감 연구를 동시에 수행하기 위하여 $1000-1400^{\circ}C$의 고온에서 순산소 가스화 연구를 수행하였다. 폐기물 시료로는 RPF (Refused Plastic Fuel)를 이용하였으며 실험 장치로는 열중량 분석기와 0.5 ton/day의 pilot plant 가스화 시스템을 이용하였다. 열중량 분석기에서는 이산화탄소에 의한 RPF 촤(char)의 가스화 실험을 수행하여 온도에 따른 중량 변화를 고찰하고 Boudouard reaction에 의해 일산화탄소가 생성되는 것을 확인하였다. 또한, 0.5 ton/day pilot plant system에서 RPF의 순산소 가스화를 통하여 고농도의 수소를 함유한 합성가스를 생산하였다. 생산된 합성가스는 수송용 연료 생산과 화학제품 생산에 가능한 수소와 일산화 탄소의 비율을 나타내었다.
