生物柴油的设备

As a green regenerated energy source, bio-diesel is important to environment care. It has wide used foreground. Our technology of producing bio-diesel including 3 kinds:1.The technology of producing bio-diesel by acidifying oil (subsurface channel oil, hogwash oil)The acidifying oil has plentiful of fatty acid (the content is above 40 60%). If react directly, the reaction process is long and difficult to react every inch. So firstly we use the technology of fractional distillation to separate the acidifying oil into neutral oil and fatty acid by the process of depickling. Secondly, go along with ester-interchange reaction by adding methanol alcohol and actalescent catalyst in neutral oil , adding methanol and acidic catalyst. After the two reactions it can gain bio-diesel and plant asphalt by fractional distillation.The technique has widely used in all kinds of raw materials. The product is high quality and yield percentage. It is environment cared and energy saved.
