Abstract: Adopting a new type of resin catalytic reactor, analyze the effects of resin type, reaction temperature, resin addition amount, and resin usage frequency on the acid reduction of biodiesel. The research results indicate that resin C has the highest transesterification efficiency. The optimal conditions for the process are a resin addition of 15% and a reaction temperature of 75 ℃. Under this reaction condition, the resin was reused 5 times and no significant decrease in catalytic activity was observed.
Keywords: biodiesel; acid reduction; strong acid resin catalyst
生物柴油具有與石化柴油相似的燃料特性,同時具有低排放、生物可降解、無毒、潤滑性強等優(yōu)點[1-2],已成為傳統(tǒng)化石燃料的優(yōu)良替代品。(剩余4792字)
