Research Interests:
Dr. Luss's group is currently conducting research on several topics. The main emphasis is on problem related to the reduction of environmental emissions from diesel engines. These include enhancement of the efficiency and safety of the regeneration diesel particulate filters, development of novel catalyst architectures which improve the destruction of NOx and organic compounds emitted by diesel engines. We also conduct studies of novel synthesis of solid oxides and the dynamic features of the combustion of solid nano-particles. Specific research projects include:
Combustion of soot in diesel particulate filters
Particulate solid particles (soot) emitted by diesel engines are a serious health hazard as they can cause cancer. The best technology for its removal is by use of special ceramic and periodic combustion of the accumulated particulate matter. Experience has indicated the transient change in the load of the engine leads sometimes to excessive unexpected temperature excursions that can melt and /or crack the expensive catalyst. We are conducting both experimental and simulation studies that aim to determine the operating conditions and driving modes that can lead to these excessive temperature rise in order to enable development of control protocols that will circumvent these undesirable dynamic behavior.
Development of temperature waves during soot combustion in a Diesel Particulate Fiter (DPF)
Flow pattern in a DPF
Development of novel catalyst Architecture
A major research activity in the department is the reduction of NOx emissions in the oxidizing exhaust emissions of diesel engines. This reduction may be conducted by use of selective Catalytic reduction catalyst (SCR) which required feed of ammonia precursor or by use of Lean NOx Trap (LNT) which contains expensive precious metals. Another option is the use a reactor with LNT catalyst followed by one with SCR to avoid the need to inject ammonia precursors. We are conducting both experimental and simulation studies of novel catalyst architecture with goal to enable a reduction of the expensive precious metal without affecting the effectiveness of the NOx destruction.
Novel temperature measurements of temperature in honeycomb reactors.
The presence of excessive high local temperatures (hot spots) can severely damage chemical reactors and monolith reactors used to destruct environmental pollutants. There is a technological to detect the amplitude and motion of small hot zones the location of which is not known and which may meander with time. We have recently developed a novel technique for measuring the spatio-temporal temperature, which measures a continuously the temporal temperature profile along a special optical fiber. The technique is currently used to measure the temperature profiles in a monolith reactor and a packed bed reactor in which several reactions are conducted. This novel technique is expected to lead to major advances in the measurements and control of temperature in chemical reactors and provide essential information that could not have been obtained until now.
Nano-particles synthesis and pressure release during their combustion
We have developed a novel method for the synthesis of solid oxides by having a high temperature front propagate through a mixture of carbon and some minerals. The method (which has a 2mm spatial resolution and temperature resolution of 0.5 C) enables a more economic synthesis than do other methods. Moreover, it can be used directly to produce nano-particles. We conduct studies on the impact of the operating conditions and reactants mixture composition on the product properties and the magnitude of the amplitude and duration of the pressure pulse generated by the released gaseous products and its dependence on the nano particles size.
