Commercial olefin manufacture by oligomerization typically produces a Shultz-Flory distribution. Chemical industry is keenly interested in carbon chain length selective olefin production. This presentation will report the results of our investigation 1-butene conversion using cobalt oxide supported on nitrogen doped carbon. The cobalt catalyst was highly selective for 1-butene dimerization producing &gt;95% C8 olefins at high selectivity to linear, internal octenes. Through varying experimental parameters our team found increasing 1-butene conversion lowered selectivity to linear octenes. Analysis of the cobalt on N-doped carbon revealed both Co3O4 and CoO with the Co3O4/CoO ratio decreasing with increasing pretreatment temperature. Our mechanistic hypothesis to explain the system’s propensity for dimerization and selectivity to linear octenes will be discussed.
