Importance of the Hydrocracking Catalyst and Separate Deoxygenation/Hydrocracking Steps for Maximizing Biojet Fuel Production from Triglyceride |
| 초록 |
Various parameters in the catalytic hydroconversion of triglycerides were investigated for maximizing the production of biojet fuel. The results demonstrated that the two-step reaction process composed of separate hydrotreating/hydrocracking steps is more advantageous than the single-step process in terms of high biojet fuel yield, suppressed production of aromatic compounds, and long catalyst lifetime. In the two-step process, the diffusion characteristics of the multibranched hydrocarbon in the hydrocracking catalysts could be correlated with the biojet fuel yields and the iso/n-paraffin ratios. Consequently, Pt supported on nanocrystalline large-pore BEA zeolite produced the largest biojet fuel yield with highest iso-paraffin content as a result of suppressed overcracking. Under the optimized conditions, 55 wt% of biojet fuel with respect to palm oil was achieved after final distillation, which satisfied all the required fuel specifications. |
