摘要：

Production of bioethanol from biomass has been known in almost worldwide. Grain-based bioethanol production generally yields a by-product known as DDGS (dried distiller grains with soluble). DDGS is potentially convertible into biocrude oil due to the lipid, carbohydrate, and protein content. One of the technologies for the production of biocrude oil from solid biomass is hydrothermal liquefaction. In this study, hydrothermal liquefaction of DDGS was conducted using ethanol solution as a reaction medium. The process was carried out under various temperatures, ratios of DDGS to reaction medium, and ethanol concentrations (15-99.5%). A high yield of biocrude oil was recovered at 280 degrees C and ratio between DDGS and 75% of ethanol solution as 1: 20. It was found that around 38.2% of biocrude oil was recovered from DDGS. Thus, DDGS has the potential to be converted into biocrude oil.
