Hydrocracking of crude palm oil to a biofuel using zirconium nitride and zirconium phosphide-modified bentonite

“…1c was likely unobserved, which could be attributed to the possibility that zirconium phosphide was highly irregular on the bentonite's surface or, due to a low percentage concentration, was employed with high dispersions, which lay below the detection limit of the analysis. 52 A similar nding was reported by Amaya et al 22 who modied the acid properties of dealuminated bentonite using AlZr or AlCe. The broadband 2q peak of Na-bentonite at 5.80 was less noticeable aer modication, indicating the lessordered bentonite-ZrP and bentonite ZrN.…”
