Abstract

Ni2P/silica and Ni2P/HY were prepared and for the first time tested in hydroprocessing of soybean oil. The content of Ni2P in each catalyst was about 25 wt%. The experiments conducted in a trickle-bed reactor operated at conditions normally used in such processes, yielded high hydrodeoxygenation (HDO) activity of both catalysts. No apparent hydrocracking activity was recorded with Ni2P/silica while Ni2P/HY displayed high hydrocracking and isomerization activity that diminished with time on stream. Characterization of the fresh and spent Ni2P/HY indicated that exposing the catalyst to water vapors generated by hydrodeoxygenation reduced the acidity of the catalyst thus reducing its hydrocracking activity. After removal of >99.5% oxygen by HDO of soybean oil and separation of water vapors, the Ni2P/HY material displayed stable operation during >250 h on stream yielding up to 50 vol% of light fraction boiling out at <250 °C.
