  • Olefin Oligomerization Processes and Related Zeolites and Structure Directing Agents
    Publication number: 20200325084
    Abstract: The disclosure relates to olefin oligomerization processes and related zeolites and structure directing agents. The olefin oligomerization processes can exhibit relatively high conversions. The zeolites can exhibit comparatively high stabilities. The zeolites can have relatively high ratios of external surface area to total surface area. An exemplary zeolite is a beta zeolite having a relatively high ratio of external surface area to total surface area. The disclosure also relates to structure directing agents, and methods of using the structure direction agents to prepare the zeolites.
