摘　　要：Development and use of the structured catalysts and reactors(SCRs)is a promising strategy to overcome the major drawbacks encountered in the traditional packed-bed reactor due to improved hydrodynamics in the combination with enhanced heat/mass transfer,thus being a hot topic in the heterogeneous catalysis.One of the most typical SCRs is the ceramic honeycomb catalyst extensively applied in the control of automotive emissions and the reduction of nitrogen oxides from power stations.SuchDevelopment and use of the structured catalysts and reac- tors （SCRs） is a promising strategy to overcome the major drawbacks encountered in the traditional packed-bed reactor due to improved hydrodynamics in the combination with enhanced heat/mass transfer, thus being a hot topic in the heterogeneous catalysis. One of the most typical SCRs is the ceramic honeycomb catalyst extensively applied in the control of automotive emissions and the reduction of nitrogen oxides from power stations. Such honeycomb catalyst consists of thousands of opening parallel channels in millimetric diameter （to offer high void fractions for low pressure drop at high flow rates through the catalyst bed） with catalytic washcoat in micrometric thickness on the channel walls （to improve mass transfer due to the short gas diffusion distance）.
