生物质生产潜力在温带（56度N），和质量的生物质的能源生产（厌氧消化甲烷和直接燃烧）进行了调查的绿色大型藻类，石莼。藻类在陆地设施中培养，表明新鲜和浸渍的U.莴苣的甲烷产量高达271 ml CH 4 g（-1）VS，与牛粪和陆地能源作物（如草三叶草）的甲烷产量相当。与湿生物质相比，生物质的干燥导致重量比甲烷产量增加5-9倍。灰分和碱含量是使用U。莴苣直接燃烧。生物炼油概念的应用可以增加美国炼油厂的经济价值。莴苣生物量以及提高其用于生产生物能源适宜性。(C)2010爱思唯尔有限公司版权所有。
The biomass production potential at temperate latitudes (56 degrees N), and the quality of the biomass for energy production (anaerobic digestion to methane and direct combustion) were investigated for the green macroalgae, Ulva lactuca. The algae were cultivated in a land based facility demonstrating a production potential of 45 T (TS) ha(-1) y(-1) Biogas production from fresh and macerated U. lactuca yielded up to 271 ml CH4 g(-1) VS, which is in the range of the methane production from cattle manure and land based energy crops, such as grass-clover. Drying of the biomass resulted in a 5-9-fold increase in weight specific methane production compared to wet biomass. Ash and alkali contents are the main challenges in the use of U. lactuca for direct combustion. Application of a bio-refinery concept could increase the economical value of the U. lactuca biomass as well as improve its suitability for production of bioenergy. (C) 2010 Elsevier Ltd.
