Beschreibung
Zusammenfassung:	The invention belongs to the fields of petroleum chemical engineering, new energy source, comprehensive utilization of waste grease, production of bio-diesel, refining chemical engineering, green chemical engineering and organic synthesis, in particular to a production method of low-sulfur, no-sulfur and high-ester content bio-diesel. The production method of the low-sulfur, no-sulfur and high-ester content bio-diesel is characterized in that the methyl alcohol with higher water content is separated from a reaction system, the water is removed separately, and the dewatering system and the reaction system are performed under two environments at different times; the reaction temperature is controlled to 50 to 70 DEG C, and the sulfonation of oil and other side effect are avoided at the premise of not sacrificing the reaction rate; after the obtained product is detected by State Petroleum Chemical Product Quality Supervision and Inspection Center (Guangdong), the sulfur content is 7.3mg/kg, the ester content is
