微藻超临界甲醇直接酯交换法制备生物柴油
Preparation of Biodiesel from Microalgae by Direct Transesterification under Supercritical Methanol Conditions
摘要
Abstract
In this paper,the liquid bio-fuel from Chorella in large-scale cultivation was prepared by supercritical methanol transesterification.By the analysis of composition,the basic physics and chemistry characterization,the process parameters were optimized depending on the biodiesel yield.The results showed that the yield of the liquid bio-fuel from microalgae could reach up to 9 % under the reaction condition： ratio of methanol to wet algae（ca.50 % moisture） 8 ∶ 1（mL ∶ g）,reaction temperature 260 ℃,reaction pressure 9 MPa and retention time 10 min.Meanwhile,the products had similar physical and chemical properties and ingredient composition to fossil diesel.关键词
