PI: Antal, Michael J.Institution: University of HawaiiCBET-1158965This EAGER proposal deals with biomass carbonization, the characteristics of the biocarbons produced, and the combustion of bicarbons in small scale combustors. This effort is a collaboration between Prof. Antal at University Of Hawaii (UH) and the Norwegian University of Science and Technology (NUST). At UH, the biomass will be converted to bicarbon at different pressures and temperatures, and will be characterized at NUST using SEM, TGA and XRD (common tools for material and structure analysis). Using bench top combustor at NUST the combustion of bicarbon and it's characteristics will be examined. The UH students will gain an unique experience with their time split between UH and NUST, working in two different countries and two different group of advisors. Their research experiences in the two countries will be unique and complementary, with production of the bicarbon at UH and characterization and combustion of the bicarbon at NUST. The intellectual merit of the research stems from the fact that the structure, properties and burning behavior of bicarbon as a function of its initial processing parameters such as pressure and temperature are poorly understood. The proposed study will undertake a systematic study of the dependence of characteristics and combustion of bicarbon as a function of the pressure and temperature used to produce the bicarbon. Bicarbons or charcoal can be used as an environmentally benign substitute for coal as a reducing agent in the manufacture of silicon and ferro-silicon. They can also be used instead of coal for power generation, space heating and combined heat and power applications without the deleterious emissions characteristics of pulverized coal plants. Potential benefit to enhance agricultural plant growth is also cited. Since bicarbon is produced from biomass they can be considered to be carbon neutral. Thus, success and understanding of bicarbons can have significant benefits from sustainability and environmental viewpoints.

主要研究者：Antal，Michael J.夏威夷大学CBET-1158965该EAGER提案涉及生物质碳化，所产生的生物碳的特性，以及小规模燃烧器中重碳的燃烧。这项工作是夏威夷大学（UH）和挪威科技大学（NUST）的Antal教授之间的合作。在UH，生物质将在不同的压力和温度下转化为重碳，并将在NUST使用SEM，TGA和XRD（材料和结构分析的常用工具）进行表征。本文将利用南京科技大学的实验台对重碳燃料的燃烧及其特性进行研究。UH的学生将获得一个独特的经验，他们的时间分配在UH和NUST之间，在两个不同的国家和两个不同的顾问组工作。他们在这两个国家的研究经验将是独特的和互补的，在UH和NUST的表征和燃烧的重碳的生产。这项研究的智力价值源于这样一个事实，即对重碳的结构、性质和燃烧行为作为其初始加工参数（如压力和温度）的函数的了解甚少。拟议的研究将系统地研究作为用于生产重碳的压力和温度的函数的重碳的特性和燃烧的依赖性。在硅和硅铁的生产中，碳酸氢盐或木炭可作为煤的环境友好替代物作为还原剂。它们还可以代替煤用于发电、空间供暖和热电联产应用，而没有粉煤厂的有害排放特性。还提到了促进农业植物生长的潜在效益。由于重碳是由生物质产生的，因此它们可以被认为是碳中性的。因此，从可持续性和环境角度来看，成功和了解碳酸氢盐可带来重大惠益。
