WebInitial studies of the activity of SCALMS for oligomerization of ethylene were carried out using an alloy of 1.5 at% Ni in Ga supported on silica (Ga 67 Ni/SiO 2) at 260 °C. Fig. 2 shows the ethylene conversion (X ethylene) and C4 alkene selectivities (S C4-alkenes) during the catalytic reaction for 24 h time on stream (TOS).The catalyst showed … WebThe oligomerizationof olefins such as ethylene and butylenes is another route for increasing the carbon number for the production of motor fuels. The ethylene and butylenes are derived by dehydration of bioethanol and biobutanol, respectively, in presence of solid acid catalysts.
