Enhancement of Propene Formation by Co-feeding Ethene and Synthesis Gas on Co/SiO₂ Catalyst

抄録

Trial to synthesize propene from ethene was carried out on silica supported cobalt (Co/SiO₂) catalyst by using slurry bubble column reactor. Catalytic propene formation was recognized on that catalyst. When a gas mixture of ethene and synthesis gas (syngas), which is 1:2 mixture of carbon monoxide and hydrogen was fed onto Co/SiO₂ catalyst, the produce rate of propene was increased 4-fold as much as that in the case flowing ethene alone. It was conjectured that the enhancement of propene formation in the presence of ethene and syngas was caused by increase methylidene (=CH₂) species which was readily reacted with ethene to form propene.
