Dissertation Enhancement Award: Dioxin Formation in Thermal Processes and Its Relationship to Carbon-Chlorine Bond Levels in Particles

9729670Altwicker本学位论文增强奖支持Elmar Altwicker博士团队的研究生Shawn Ryan先生在卡尔斯鲁厄国家研究中心技术化学研究所的Ludwig Stieglitz博士的实验室度过三个半月。在此期间，瑞安将对各种碳中的碳-氯(C-Cl)键进行定量测定。在一定浓度和速率下，残留碳中C-Cl键的形成在二恶英的形成中起着重要作用，二恶英是包括垃圾焚烧在内的许多热过程的不良副产物。在德国实验室完成的这项工作可能有助于开发将热过程中产生的二恶英降至最低的技术。

9729670AltwickerThis dissertation-enhancement award supports Mr. Shawn Ryan, a graduate student, in Dr. Elmar Altwicker's group at Rensselaer Polytechnic Institute to spend three-and-a-half months in the laboratory of Dr. Ludwig Stieglitz of the Institute for Technical Chemistry at the National Research Center in Karlsruhe. While there, Mr. Ryan will make quantitative determinations of carbon-chlorine (C-Cl) bonds in various carbons. The formation of C-Cl bonds in residual carbons at certain concentrations and rates plays an important role in the formation of dioxins, which are undesirable by products of many thermal processes, including waste incineration. The work done in the German lab could aid in the development of techniques to minimize Dioxin formation in thermal processes.
