Conclusions
-
1.
The existence of synergism is demonstrated; the activity of Pd-Tc/carrier catalysts in the dehydrogenation of hydrocarbons considerably exceeds that of monometallic catalysts. The most active catalysts are those with Pd∶Tc ratios from 1∶1 to 2∶3.
-
2.
In terms of reactivity on Pd-Tc catalysts, the hydrocarbons are arranged as follows: cyclohexene > cyclohexane > methylcyclohexane > ethylcyclohexane > n-hexane.
-
3.
Activity in the dehydrogenation of cyclohexane varies as follows: Pd-Tc/γ-Al2O3 > Pd-Tc/MgO > Pd-Tc/TiO2 > Pd-Tc/Y2O3 > Pd-Tc/SiO2.
-
4.
A decrease in CO chemisorptive capacity on bimetallic catalysts compared to monometallic catalysts is established.
