Production method of biodiesel using Aleurites moluccana fruits as raw materials
InactiveCN105670805AImprove qualityHigh yieldFatty acid esterificationBiofuelsNano catalystBiodiesel
The invention discloses a production method of biodiesel using Aleurites moluccana fruits as raw materials. The method comprises the following steps: adding a diatomite adsorbent, and carrying out pretreatment for Aleurites moluccana fruit oil in order to obtain pure Aleurites moluccana fruit oil; adding the pure Aleurites moluccana fruit oil, methanol and the magnetic nano-catalyst according to a weight ratio 100:25-35:0.3-0.5 into a reaction vessel for carrying out an esterification reaction; and a biodiesel crude product is separated and purified in order to obtain the biodiesel. The magnetic nano-catalyst is introduced into the esterification reaction with high catalysis efficiency and substantial catalysis effects, so that reaction time is shortened, and yield of biodiesel is increased; on the other hand, the magnetic nano-catalyst can be conveniently and rapidly separated and recycled by means of an exterior magnetic field, and multitime cycle and utilization are carried out. The method also has the advantages of short reaction time, high yield, high product purity, etc.; the method has good social efficiency, ecological benefits, and economic benefits; large scale and industrial production are easy to realize.
