CAREER: Carbonaceous Particles of Tarry Origin

该项目将描述固体燃料燃烧过程中产生的碳质颗粒的物理和化学特性。 这些来源的颗粒物受到的关注比其他来源的少，但估计约占全球排放量的2/3。 该项目将包括实验室和实地研究，包括使用本研究开发的两级热解反应器检查燃料在燃烧的各个阶段的排放，分析从广泛使用固体燃料的地点收集的样品（主要是第三世界亚洲国家）与实验室结果进行比较，工作计划包括一个广泛的目标，以提高学生和公众对国际空气质量问题的认识。 观察和数据分析将被纳入一个类，将包括讨论和统计方法的应用。 排放清单的概念将与数据库查询模型一起沿着使用，作为一种工具来展示各种类型和位置的排放对大气颗粒物含量的影响。 这一模式还将作为一种网络工具提供。 客座讲师，在国际空气质量问题的专业知识，将被邀请到PI的机构与学生在部门和更广泛的大学社区的成员进行互动。 两名研究生将在该计划下接受培训。 这项研究将导致更好地代表含碳颗粒的化学传输模型。 燃烧和大气化学领域之间的联系将得到改善，国际研究人员和非营利组织之间的合作将得到加强。 产生基于燃烧的粒子的设施将有助于社区进行校准和仪器相互比较。

This project will characterize the physical and chemical properties of carbonaceous particles generated in the combustion of solid fuels. Particles from these sources have received less attention than from other sources, but are estimated to account for roughly 2/3 of the global emissions. The project will involve a mixture of laboratory and field studies that include examining the emissions from fuels in various stages of combustion using a two-stage pyrolytic reactor developed in this study, analyzing samples collected from locations for which solid fuels are widely used (primarily third world Asian countries) to compare with the laboratory results, and development of schemes for incorporation of these results into models.The work plan includes a broad goal to improve understanding of international air-quality issues for students and the general public. Observations and data analysis will be incorporated into a class that will include discussion and application of statistical methods. The concept of emission inventories will be used along with a database query model as a tool to demonstrate the impacts of various types and locations of emissions on atmospheric particulate content. This model will also be made available as a web-based tool. Guest lecturers, with expertise on international air quality issues, will be invited to the PI's institution to interact with students in the department and with members of the wider university community. Two graduate students will receive training under this program. This research will lead to better representation of carbon-containing particles in chemical transport models. Links between the fields of combustion and atmospheric chemistry will be improved, and collaborations between international researchers and non-profit organizations will be enhanced. The facility for generating combustion-based particles will be useful to the community for calibration and instrument intercomparison.
