Abstract

Syngas can be used as raw material for chemical and fuel production. Currently, many studies on syngas production from gasification of biomass have been conducted. Kenaf is a promising renewable resource with high productivity and CO2 immobilization. This study developed a large-scale kenaf gasification process based on the experimental data, and evaluated the techno-economic feasibility, which consists of three steps (integrated process design, heat exchanger network design, techno-economic assessment). The minimum selling price of syngas is US$ 9.55/GJ, and it is lower than current market price of syngas.

합성가스는 화학제품 및 수송연료의 원료로 이용되며, 최근 목질계 바이오매스의 가스화를 통한 합성가스 생산기술에 대한 연구가 다수 진행되었다. 케나프는 높은 생산성과 이산화탄소 흡수율을 가지는 목질계 바이오매스로 이산화탄소 저감을 위한 대체자원으로서 활용 가능성이 높다. 본 연구는 케나프 가스화 실험연구 데이터를 바탕으로 상용 수준의 케나프 가스화 공정을 개발하고, 해당 공정의 타당성 및 실현가능성을 평가하는 연구로서, 케나프 가스화 통합공정 설계, 열교환망 설계, 기술경제성 평가로 구성된다. 개발된 공정으로부터 생산되는 합성가스의 최소판매가격은 1 GJ당 9.55 달러로, 합성가스의 시장가격보다 낮은 것을 확인하였다.
