Abstract

The metal foil carriers for the catalysts with internal electroheating were studied in the paper. The samples were synthesized by implanting aluminum ions into a stainless foil and a subsequent impregnation with palladium. An important characteristic for the catalysts is the process temperature. That is why, in this research, the implant surface temperature as a determining factor of a heterogeneous catalytic process was chosen as the objective function. Studying the effect of the electric flux power, air flow rate and synthesis on the sample temperature was carried out using the method for recovering one-dimensional dependencies. As a result of the modeling, the optimal ranges of varying the process parameters were determined. It was shown that the electric flux power and the synthesis had a significant influence on the surface temperature, and the effect of the air flow rate was negligible. The obtained results allow effectively controlling electricoheating of the steel samples and can be applied in the construction of heat-exchange and catalytic elements with internal heating.
