This present disclosure relates to catalytic processes for upgrading crude and/or refined fusel oil mixtures to higher value renewable chemicals, via mixed metal oxide or zeolite catalysts. Disclosed herein are processes passing a vaporized stream of crude and/or refined fusel oils over various mixed metal oxide catalysts, metal doped zeolites, or non-metal doped zeolites and/or metal oxides providing options to valorize fusel oil mixtures to higher value products. Renewable chemicals formed, via these upgrading catalyst platforms, are comprised of, but not limited to, methyl isobutyl ketone (MIBK), di-isobutyl ketone (DIBK), isoamylene, and isoprene.
本公开涉及通过混合金属氧化物或沸石催化剂将原油和/或精炼燧石油混合物升级为更高价值的可再生化学品的催化工艺。本发明公开了将汽化的原油和/或精炼燧石油流通过各种混合金属氧化物催化剂、掺杂金属的沸石或掺杂非金属的沸石和/或金属氧化物的工艺,提供了将燧石油混合物提纯为高价值产品的选择。通过这些升级催化剂平台形成的可再生化学品包括但不限于甲基异丁基酮 (MIBK)、二异丁基酮 (DIBK)、异戊二烯和异戊二烯。
