Biodiesel Production Line suppliers Because Chinese national condition is restricted, the acid value of blame edible feedstock oil that is used at preparation biology derv is higher. Such, alkalescent activator is in microtherm (like 50 ¡æ ) preparation biology derv is incidental severe saponification reaction. And when derv of biology of acidity activator preparation, although do not have saponification reaction, but the reaction temperature with higher demand (be like 220 ¡æ ) , very tall also to the quality requirement of equipment, at the same time perishable corrode equipment.

The Chinese Academy of Sciences on the west Wang Yi of graduate student of Master of group of energy of biology of arboretum of tropics of double edition accept is together below the guidance of researcher Fang Zhen, synthesized Mg-Al water successfully grain of steatitic accept rice, the small phoenix tree and tung tree that its activation hind uses at catalytic high acid value child the derv of biology of preparation of mixture soybean oil of oil and high acid value. Experimental result makes clear: Grain of this accept rice is had better fight acidity, in reaction temperature oily Maerbi mixes alcohol of 160 ¡æ , 5% activator, 30/1 below the reaction time condition of 4h, catalytic acid value is the small phoenix tree and tung tree of 6.3 child oily, the yield of biology derv can be achieved 93.4% , it is the derv of biology of preparation of mixture soybean oil of 12.1 when catalytic acid value, yield can be achieved 92.9% . Grain of this accept rice repeats use 4 times, the yield of biology derv still can achieve 86% above. Grain of steatitic accept rice shows the Mg-Al water after activation good catalytic performance.

Relevant research achievement is published on Bioresource Technology of periodical of international the sources of energy for the problem with One-step Production Of Biodiesel From Oils With High Acid Value By Activated Mg–Al Hydrotalcite Nanoparticles.
