化石燃料储量减少、能源安全需要增加以及对化石燃料使用产生的碳排放的关切,是全球推动替代、可再生、生物可再生燃料和化学品的动力。本文报道了灰绿烟草叶中长链(C29-C33)饱和烃的鉴定。这些碳氢化合物的存在是通过气相色谱-质谱法(GC-MS)检测的,并通过比较可用的真实标准品所显示的物理化学性质来确认。一个简单的,强大的程序开发,使提取物的生成含有高百分比的烃(6.3%重量的干叶材料)高于以前的报告中的其他高等植物物种。对于生物燃料生产来说,白兰花可能是一种比以前认识到的更重要的作物。该植物可以在边缘土地上生长,无需与粮食作物或农田竞争,并且可以以非侵入性方式生产烃提取物,使剩余的生物质完整地用于生物乙醇生产和产生有价值的副产品。
Declining fossil fuels reserves, a need for increased energy security and concerns over carbon emissions from fossil fuel use are the global drivers for alternative, renewable, biosources of fuels and chemicals. In the present study the identification of long chain (C29–C33) saturated hydrocarbons from Nicotiana glauca leaves is reported. The occurrence of these hydrocarbons was detected by gas chromatography–mass spectrometry (GC–MS) and identification confirmed by comparison of physico-chemical properties displayed by the authentic standards available. A simple, robust procedure was developed to enable the generation of an extract containing a high percentage of hydrocarbons (6.3% by weight of dried leaf material) higher than previous reports in other higher plant species consequently, it is concluded that N. glauca could be a crop of greater importance than previously recognised for biofuel production. The plant can be grown on marginal lands, negating the need to compete with food crops or farmland, and the hydrocarbon extract can be produced in a non-invasive manner, leaving remaining biomass intact for bioethanol production and the generation of valuable co-products.
