The current status of and challenges associated with bioenergy production and utilization in Korea are reviewed in this paper. Bioenergy (particularly transport biofuels) has emerged as a promising option for mitigating Korea's CO2 emissions and enhancing its energy security. Korea's limited...

Microalgae, as biodiesel feedstock, are promising renewable energy sources that can be continuously developed into the future. Because recovery of microalgal lipid from dry microalgae incurs high costs, particularly in the dewatering process, wet extraction has been suggested as an attractive...

In this study, pre-biodiesel-production lipid extraction from microalgae (Chlorella vulgaris) was performed. The yield-enhancing effects of ionic liquid blends on the lipid extraction were investigated. The initial fatty acids content of the C. vulgaris was 292.2 mg/g cell. The lipid...

Deoxygenation of microalgal oil obtained by pyrolysis of microalgae was carried out for the production of hydrocarbon fuel from biomass by metal supported catalyst. Oleic acid was used as a model reactant to select an optimized catalyst. Effects of support, metal species, and metal loading on...

Ce(1–x)Zr(x)O2 catalysts were prepared by co-precipitation method for deoxygenation (DO) of oleic acid. The CeO2/ZrO2 ratio was systematically varied to optimize Ce(1–x)Zr(x)O2 catalysts. Ce0.6Zr0.4O2 exhibited the highest oleic acid conversion as well as high selectivity to C9 ∼ C17...

To maximize the production of biodiesel from soybean soapstock, the effects of water on the esterification of high-FFA (free fatty acid) oils were investigated. Oleic acid and high acid acid oil (HAAO) were esterified by reaction with methanol in the presence of Amberlyst-15 as a heterogeneous...

In this study, 4-methylmorpholine N-oxide (NMMO) and four ionic liquids were compared to determine the most suitable type for use in pretreatment of oil palm empty fruit bunch (EFB) to enhance enzymatic digestibility and obtain maximal fermentable sugar (glucose). Four types of ionic liquids,...
