GOALI: Soot and NOx Control in Diesel Engine Exhaust

研究了一种新型的柴油机再生过滤系统。 该系统由具有可变速度的旋转流化床反应器组成，该反应器将在低功率操作期间收集烟灰，并且在温度足够高的高功率操作下使收集的烟灰与NOx反应。 颗粒催化剂用作烟灰保留的过滤介质和NOx还原的促进剂。 催化剂的操作对于过滤系统的成功至关重要。 计划进行实验室和试验站实验。 一个单一的催化剂颗粒模型将被开发作为参考进行和解释实验。 一组公司，包括炼油公司（埃克森美孚，美孚技术公司），催化剂制造商（Engelhard Co.，美铝、约翰逊万丰）和柴油发动机制造商（康明斯、福特、梅赛德斯-奔驰、沃尔沃）将通过提供实验和技术反馈支持以及提供部分资金来合作该项目。工业合作伙伴将提供实物捐助，参与研究，并为大学研究部分提供资金支持，满足GOALI项目的要求。 NJIT将承担设备成本的50%。 NJIT团队拥有来自化学工程、化学和数学的合作伙伴。 四个项目共同审查了该提案：流体，颗粒和液压系统（FPHS），化学反应过程（CRP），环境技术（ET）和GOALI。

A novel regenerating filtration system for Diesel engines will be investigated. The system consists of a rotating fluidized bed reactor with a variable speed that will collect soot during low power operations, and react the collected soot with NOx at high power operations where the temperature is sufficiently high. The particulate catalyst acts as filter medium for soot retention and promoter of the NOx reduction. The operation of the catalyst is essential to the success of the filtration system. Laboratory and pilot station experiments are planned. A single catalyst granule model will be develop to be used as reference in conducting and interpreting the experiments. A group of companies, including petroleum refining companies (Exxon, Mobil Technology Co.), catalyst manufacturers (Engelhard Co., Alcoa, Johnson Matthey) and Diesel engine manufacturers (Cummins, Ford, Mercedes-Benz, Volvo) will collaborate to the project by providing support to experiments and technical feedback, and supplying partial funding. Industrial partners will provide in-kind contributions, participate to research, and support with funds the university research component, satisfying the requirements for a GOALI project. NJIT will contribute 50% of the cost of equipment. The NJIT team has the co-P.I.s from chemical engineering, chemistry, and mathematics. Four programs have co-reviewed this proposal: Fluid, Particulate and Hydraulic Systems (FPHS), Chemical Reaction Processes (CRP), Environmental Technologies (ET), and GOALI.
