A vitamin E production method and a vitamin E production device which can highly purify vitamin E in a vitamin E concentrated fraction are provided. A raw oil supply section supplies a raw oil to a series column in which two or more columns including a strongly basic anion exchanger are coupled in series to adsorb vitamin E included in the raw oil on the strongly basic anion exchanger of at least one column from among the series column. A desorption solution supply section supplies a desorption solution to a column on which vitamin E has been adsorbed to desorb vitamin E from the strongly basic anion exchanger of the column.

Catalysts and methods for use in conversion of glycerides and free fatty acids to biodiesel are described. A batch or continuous process may be used with the catalysts for transesterification of triglycerides with an alkyl alcohol to produce corresponding mono carboxylic acid esters and glycerol in high yields and purity. Similarly, alkyl and aryl carboxylic acids and free fatty acids are also converted to corresponding alkyl esters. Catalysts are capable of simultaneous esterification and transesterification under same process conditions. The described catalysts are thermostable, long lasting, and highly active.

A process for production of biofuels from algae can include cultivating an oil-producing algae by promoting sequential photoautotrophic and heterotrophic growth. The method can further include producing oil by heterotrophic growth of algae wherein the heterotrophic algae growth is achieved by introducing a sugar feed to the oil-producing algae. An algal oil can be extracted from the oil-producing algae, and can be converted to form biodiesel.

A chocolate that has a reduced trans fatty acid content and still has a high compatibility with cocoa butter, high blooming resistance and good meltability in the mouth. A transesterified fat or oil has a content of unsaturated fatty acids controlled such that it is 10 mass % or less in the constituent fatty acid composition thereof, and the composition of other fatty acids is adjusted to a preset content.

The present invention discloses a method for co-production and processing of biological energy sources by oil crops, and belongs to the technical fields of oleochemical industry and biomass chemical industry. The method comprises the following steps: husking and drying oil crop seeds to obtain husks of which the moisture content is 5%-12% and oil seeds of which the moisture content is 30%-55%; squeezing and extracting the obtained oil seeds to obtain vegetable oil and oil seed meal; performing esterification reaction on the vegetable oil and alcohol to be separated to obtain bio-diesel and crude glycerol; performing cooking treatment on the husks and/or the oil seed meal in the crude glycerol to be separated to obtain oil crude cellulose and glycerol treating liquid; performing microbial fermentation or anaerobic digestion on the oil crude cellulose and the glycerol treating liquid respectively to obtain biological energy sources or bio-based chemicals. The present invention adopts bio-refining type recycling of industrial oil crops to realize efficient co-production of biological energy sources and obviously increase the utilization rate of biomass raw materials in agriculture and forestry.
