Kinetics of Ethylene Oligomerization on NiO/B <sub>2</sub>O <sub>3</sub>-Al <sub>2</sub>O <sub>3</sub> in Liquid Phase
The reaction kinetics of ethylene oligomerization on NiO/B2O3-Al2O3 in medium of liquid solvent (heptane) was investigated using ﬂow integral method in the range of temperature 50-200 °C and in the range of ethylene`s weight-hourly space velocity 0,25-2,0 h  -1 . It was shown that alkenes C4-C14 are products of the ethylene`s conversion process under these conditions. The content of high-molecular hydrocarbons in product`s composition increases while the conversion of ethylene extends. The kinetic model of the process taking into account stages of ethylene dimerization, interaction of ethylene with alkenes C4+, interaction of butenes with each other and with oligomers C6+ was suggested.
