Biojet Production from Hydroisomerization of Palm Olein Catalyzed by Ni/Micromesoporous Zeolite Composite Supports.

ABSTRACT: This study investigated the catalytic performance of Ni-based catalysts supported on micromesoporous composites derived from the incorporation of SBA-15 with USY-(SBA-15-xUSY) or Hbeta-(SBA-15-xHbeta) zeolites (where x is wt percentage of zeolite fraction in the composite) for palm oil hydroisomerization to produce biojet fuel range. The hydroisomerization was conducted in a fixed-bed reactor under 25 bar of H2 pressure at 40 mL/min, 425 °C, 0.1 mL/min palm oil feed rate, and 5 g of catalyst. It was observed that the support materials significantly influenced catalytic activity and product selectivity. In the case of zeolite supports, the Ni-based catalysts supported by USY zeolite showed the highest liquid product yield (54.3 wt %) and iso-to-normal (i-/n-) alkane ratio of 1.43, whereas t
