Abstract
This present disclosure relates to catalytic processes for oligomerizing bio-based olefinic mixtures to higher value renewable fuels via a doped Chabazite zeolite catalyst. A stream including a C-Colefin and an oxygenate is fed to an oligomerization process utilizing a doped Chabazite zeolite catalyst resulting in high yields and selectivity of oligomers used to produce bio-based jet fuel and/or diesel fuels depending upon reaction temperatures and pressures. The process also produces iso-octane that is suitable for producing bio-based gasoline. The process tolerates relatively high levels of oxygenates in the olefinic feed and the catalyst is capable of air regeneration.
