Abstract:
In order to effectively extract bio-oil from raw materials which can be used for manufacturing biodiesel, less moisture improves oil extraction efficiency. However, in order to remove moisture from oil containing microorganism, additional processing costs are required, so a new oil extracting method of which the oil extraction efficiency is excellent is required. The present invention relates to a bio-oil manufacturing method capable of extracting moistened oil comprising the following steps: adding clay into a culture medium including oil containing microorganism and depositing the microorganism; adding peroxides into the deposited microorganism and degrading cell walls; and recovering an oil layer discharged from the microorganism. According to the bio-oil manufacturing method capable of extracting moistened oil, the high efficiency extraction of bio-oil which is a raw material for biodiesel from oil containing microorganism is possible, and the method can be utilized in a manufacturing process of fatty acid such as omega-3 fatty acid containing DHA and EPA.

PURPOSE: A method for manufacturing raw oil for biodiesel and a method for manufacturing the biodiesel using the raw oil are provided to effectively remove phospholipid from oil obtained from biomass and to raise the yield rate of the raw oil. CONSTITUTION: A method for manufacturing raw oil for biodiesel includes: a step of removing solid matters from oil obtained from biomass containing the oil and fat; a step of determining the amounts of a sulfuric acid catalyst and methanol using a central composite design based on a response surface method; and a step of esterifying the oil without degumming under a condition in which the sulfuric acid catalyst and the methanol exist with the determined amounts in order to remove phospholipid and free fatty acid from the oil below a predetermined content. The biomass from gum tree is a tropical crop containing over 40 ppm of the phospholipid. A reaction system includes below 0.6 to 1.0 percentages of the sulfuric acid catalyst against the weight of the oil according to the central composite design based on the response surface method. The reaction system includes 20 to 30 percentages of the methanol against the weight of the oil, and the content of the phospholipid removed through esterification is 10 ppm or less.
