Abstract

화석 연료 매장량의 고갈과 에너지 소비의 증가로 인해 청정 대체 에너지원에 대한 필요성이 증가했습니다. 당화, 발효 및 화학적 전처리는 저렴하고 재생 가능한 자원인 리그노셀룰로오스 바이오매스(LCB)를 바이오에너지 잠재력으로 전환할 수 있습니다. 이후 단계에서 LCB를 바이오연료나 생화학물질로 전환하려면 화학적 전처리가 필수적입니다. LCB 접근성과 소화를 개선하려면 특정 업그레이드된 전처리가 필요합니다. 셀룰로오스 및 헤미셀룰로오스와 같은 탄수화물의 가수분해를 향상시키는 것은 LCB 전처리에서 불가피합니다. 바이오제품을 생산하려면 리그노셀룰로오스의 내화 구조가 변형되어야 합니다. LCB로부터 바이오에너지를 생산하기 위해 다양한 전처리 기술이 개발되었습니다. 산성, 알칼리성, 유기용매, 심층 공융 용매(DES) 및 습식 산화 화학적 전처리 기술(CPT)의 최신 개발을 검토하고 논의합니다. 이 연구는 이러한 전처리 절차와 현대 바이오리파이너리 발전을 위한 환경 친화적 기술로서의 잠재력에 대한 이해를 높이는 것을 목표로 합니다.

The need for clean, alternative energy sources has increased due to the depletion of fossil fuel reserves and rising energy consumption. Saccharification, fermentation, and chemical pretreatment can turn lignocellulosic biomass (LCB), an affordable and renewable resource, into bioenergy potential. Chemical pretreatment is essential to convert LCB into biofuels or biochemicals in later stages. Certain upgraded pretreatments are required to improve LCB accessibility and digestion. Enhancing the hydrolysis of its carbohydrates, such as cellulose and hemicelluloses, is the inevitable of the LCB pretreatment. In order to produce bioproducts, lignocelluloses must have their refractory structure modified. Different pretreatment techniques have been developed to produce bioenergy from LCB. The most current developments in acid, alkaline, organosolv, deep eutectic solvents (DESs), and wet oxidation chemical pretreatment techniques (CPT) are reviewed and discussed. The study aims to increase our understanding of these pretreatment procedures and their potential as environmentally friendly technologies for advancing contemporary biorefineries.
