Abstract

This study investigated to understand the trend of international commercializing technologies and industrial status of the transportation biofuel based on lignocellulosic biomass. Two major commercializing technologies for the lignocellulosic biofuel are biochemical conversion technology and thermochemical conversion technology. It was reported that a total of 93 industrial companies were using lignocellulosic biomass of all facilities related to advanced biofuel. On the basis of commercial type, the biochemical conversion technology was identified to be the major technology in the lignocellulosic biofuel industries, showing 84% of all. Also the main products of commercial type industrial companies are bioethanol (1,155,000 tons/yr) and bio-oil (120,000 tons/yr), which are in a remarkably inadequate amount to substitute for the transportation biofuel worldwide. It was suggested that the transportation biofuel market was currently in need of further development in both technology and scale, and was in high demands of technological development and commercializing exertion.

본 논문에서는 최근 목질계바이오매스를 원료로 한 수송용(transportation) 바이오연료의 국제적 상용화 기술의 흐름과 산업체 동향에 대하여 조사하였다. IEA, Bioenergy Task 39에서 집계한 수송용 바이오연료 관련 산업체에서 목질계 원료를 사용하는 산업체는 93개 업체였고, 그중에서 Commercial type의 산업체를 기준으로 생화학적 전환기술을 채택한 업체는 전체의 84%로 나타나 생화학적 전환공정이 목질계 바이오연료 분야의 주류 기술인 것으로 밝혀졌다. 생화학적 전환공정을 채택한 Commercial type 산업체의 주요 생산품은 바이오에탄올로서 연간 약 115만 5천 톤, 바이오오일은 약 12만 톤으로 전 세계의 수송용 연료에 혼입목표량을 대체하기에 매우 부족한 상황인 것으로 밝혀져 수송용 바이오연료 시장은 기술과 규모 면에서 기술개발과 상용화 노력이 더욱 요구됨이 시사되었다. 또한 pilot type의 산업체에서 생화학공정 및 열화학공정기술을 활용한 실험적 생산이 다수 진행되고 있어, 향후 목질계 원료에 의한 액체바이오연료 기술이 다양하게 실용화될 가능성이 큰 것으로 시사되었다.
