Research described in this proposal explores new approaches to increasing the yields of charcoal from biomass. Thermogravimetric studies of water washed, acid washed (low temperature), and acid hydrolyzed bagasse will be undertaken to determine the influence of the various components of bagasse on charcoal formation. Considerable experimental evidence has accumulated which suggests that elevated pressures and a stagnant gas environment can double the usual yield of charcoal from biomass. This phenomena will be detailed by studying biomass pyrolysis in closed, sealed crucibles using a differential scanning calorimeter to monitor heat demand. Both studies of peak pressure and substrate composition will be undertaken to gain insight into how charcoal yields from biomass can be improved. Kinetic analysis of the data will also be completed. These studies rely on complementary expertise and instrumentation available in the Renewable Resources Research Laboratory of the University of Hawaii, and the Hungarian Academy of Sciences Laboratory for Inorganic Chemistry. The research will be accomplished during exchange visits of scientists between the two laboratories. Results of this work will be particularly important to Pacific rim countries (Thailand, the Philippines, India, and China) which use substantial amounts of charcoal for cooking, and other developing countries (such as Brazil) which rely on charcoal to smelt iron ore.

该提案中描述的研究探索了新的 提高木炭产量的方法， 生物质。 水洗、酸洗和酸洗的热重研究 洗涤（低温），酸水解甘蔗渣将 以确定各种因素的影响 蔗渣组分对木炭形成的影响。 相当大 实验证据表明， 升高的压力和停滞的气体环境可 使生物质的木炭产量增加一倍。 这一现象将通过研究生物量来详细说明 在密闭的密封坩埚中使用差压进行热解 扫描量热计监测热量需求。 两项研究 峰值压力和基质成分的变化 为了深入了解木炭是如何从 生物质可以得到改善。 数据的动力学分析 也将完成。 这些研究依赖于 提供的补充专业知识和仪器， 可再生资源研究实验室 夏威夷大学和匈牙利科学院 无机化学科学实验室 研究 将在科学家互访期间完成 两个实验室之间。 这项工作的结果将 对太平洋沿岸国家尤为重要 （泰国、菲律宾、印度和中国） 用于烹饪的大量木炭，以及其他 发展中国家（如巴西）， 用木炭冶炼铁矿石。
