Conclusions

  1. 1.

    The catalyst NiO-SiO2 acquires activity in the reaction of dimerization of C2H4 when Al2O3 is introduced into it.

  2. 2.

    With increasing Al2O3 content in the catalyst, the conversion of C2H4 and i-C4H8 and the number of electron acceptor centers, recordable by ESR, pass through a maximum (1–3% Al), while the total acidity of the catalyst increases.
