Electrode of SPE water electrolyzer is prepared by surface modified Nafion 1135 membranes with direct way of CCM method,study on the performance of the electrodes with different Nafion loading on the catalyst layer and the life of the electrode;prepare large size electrode then test the performance.

The catalyst consumption decreased from 0.

In this paper, Pd-only catalysts were prepared with honeycomb ceramic monol.

Comparing with Pt and Rh, Pd is more abundant in resource, cheaper and better at light-off performance among the three kinds of rare-mental active components of TWC catalyst, and the Pd-only catalyst is playing more and more important role in the automotive emission control materals.

Simulation of the pressure drop of the catalyst bed in industrial reactor;

Generally,the multi-zone heat-exchanging mode,heat-exchanging between zones of converter,is adopted for heat extraction of catalyst bed in CO conversion reaction.

Liquid solid contacting efficiency of the catalyst bed in a catalytic distillation column,which has been industrialized,was measured by the step decrease tracer method.
