Comparison of canola oil conversion over MFI, BEA, and FAU
The catalytic conversion of canola oil was performed at atmospheric pressure with a weight hourly space velocity of 1.0 h−1 in a fixed-bed reactor at temperatures of 400 °C and 450 °C over MFI, BEA, and FAU, and with different SiO2/Al2O3 ratios for BEA and FAU. Simulated distillation of the organic liquid product showed that MFI gave the highest gasoline range product (39%, 450 °C) and lowest coke (3.2%, 450 °C) yields compared to the other zeolites. MFI produced the most C3 hydrocarbons, while BEA produced the most C4s and FAU generated the most C5s. As SiO2/Al2O3 in BEA increased from 25 to 300, the gasoline fraction yield increased from 18.5% to 25.0% at 400 °C.
