Method for co-production and processing of biological energy sources by oil crops

A method for co-production and processing of biological energy sources by oil crops, wherein the method comprises the following steps:

• (1) husking and drying oil crop seeds to obtain husks which moisture content is 5%-12% and oil seeds which moisture content is 30%-55%;
• (2) squeezing and extracting the oil seeds obtained in the step (1) to obtain vegetable oil and oil seed meal;
• (3) performing esterification reaction on the vegetable oil and alcohol to obtain bio-diesel and crude glycerol, wherein the crude glycerol is obtained by degreasing and concentration treatment;
• (4) performing cooking treatment on the husks and/or oil seed meal in the crude glycerol to be separated to obtain oil crude cellulose and glycerol treating liquid, wherein the cooking treatment comprises the processes of heating the husks and/or the oil seed meal to 230-270 DEG C., keeping the temperature for 10-20 min, and then, reducing the temperature to 70-100 DEG C.;
• or wherein the cooking treatment comprises the processes of heating the husks and/or the oil seed meal to 160-200 DEG C. in the presence of alkali, keeping the temperature for 1-20 min, and then, reducing the temperature to 70-100 DEG C.;
• (5) washing the oil crude cellulose obtained in the step (4) with water for 2-5 times, and then, performing microbial fermentation or anaerobic digestion on the washed crude cellulose and glycerol treating liquid respectively to obtain biological energy sources or bio-based chemicals.
