摘要
为了探索低成本的海藻生物油快速制取工艺技术,研究组已成功开发出一套海藻的选育、培养、收获、干制技术。利用自行优选、培养、收获并干制的海藻粉,基于课题组在生物质的微波裂解技术已取得的突破,采用自行研制的玉米秸秆微波裂解的相关设备,对微波裂解海藻制取生物燃油的技术进行试验研究,获得大量在自然条件下可分层的海藻生物油。采用气相色谱-质谱(GC-MS)分析了所得到的生物油产品中两相油组分,得到了生物油产品中的物质组成及其相对含量,可为海藻生物油的精制及其副产品的开发利用提供了参考。研究表明,微波裂解海藻是一种低成本、快速、高效制取海藻生物燃油的方法,为海藻生物油的规模化生产提供参考。
In order to explore technologies for rapid and cost-efficient bio-oil production from algae,the authors＇ research group has developed a whole set of new process for algae variety selection,culture,harvest and dehydration.Based on the previous technical breakthrough by the research group in microwave assisted pyrolysis（MAP）of biomass, the optimized algae harvested from self-cultivated tank was dehydrated and used to conduct experiments on MAP of algae to produce bio-oil using self-developed equipment for microwave assisted pyrolysis of corn stover.Some algae-based bio-oil with water-oil two-phase stratification under natural conditions was obtained.The two-phase bio-oil products were then analyzed to acquire their compositions using Gas Chromatography-Mass Spectrometry（GC-MS）;the compositions and their percentages were acquired,which can provide theoretical basis for refining algae-based bio-oil products for various usages and developing value-added by-products.The research results show that MAP of algae is a rapid,cost-competitive and efficient method for producing bio-oil,which provides reference for mass production of bio-oil from algae.
