| Abstract: |
We report an aerobic partial oxidation of isobutylene into isoprene, acetone, and para-xylene using a mesoporous Ni TiO x catalytic material. In this work, two catalysts were found to synthesize two of these three valuable products with high selectivity, with p -xylene being synthesized with a selectivity of 46.0% and isoprene being synthesized with a selectivity of 64.7%, with overall conversions of isobutylene being 34.0% and 11.9% respectively. These reactions were done at relatively low temperatures (300 °C or below) and are conducted at flow rates of 10 sccm oxygen and isobutylene. The nickel titania catalysts were studied extensively using various characterization methodologies such as TEM, Raman, XRD, and XRF. [Display omitted] • Multiple high surface area nickel titania catalysts were synthesized and studied for the partial oxidation of isobutylene. • Formed nickel titanate phases in 33.1% Ni TiO x seemed to aid in overall stability and surface area. • Depending on the concentration of nickel, different selectivity of valuable products (isoprene and p -xylene) changed. • Reactions were conducted at relatively low temperatures (300 °C). • Isoprene is of interest due to being formed without co-reactant formaldehyde.
