“…Ni metals from NiO are spread on the surface and in the pores. Moreover, silicarich sodalite zeolite have empty orbitals that can accept electron pairs from the ammonia base [47]. NiO/Z acidity increased by 41.77% from Z, NiO/ZTPA increased by 40.24% from ZTPA, and NiO/ZCTA increased by 50.87% from ZCTA.…”

NiO/silica-rich zeolite catalysts were used for coconut oil hydrocracking. The catalyst was prepared with a mixture of Na2SiO3, Al(OH)3, NaOH, and quaternary ammonium surfactants. The surfactant was varied of types like as tetrapropylammonium bromide (TPAB) and cetyltrimethylammonium bromide (CTAB). The acidity of the silica-rich sodalite zeolites enhances with the increase in nickel oxide added through a wet impregnation. The hydrocracking process was carried out by a semi-batch method. Liquid products were analyzed using GC-MS. The results showed that the addition of surfactants increased the catalyst surface area and acidity. Meanwhile, the presence of nickel oxide increases the acidity of the catalyst. The hydrocracking results showed an increase in gas products when the surface area was high, i.e., 23.781% in silica-rich sodalite zeolite without template (Z), 32.68% in silica-rich sodalite zeolite with tetrapropylammonium (ZTPA), and 39.673% in silica-rich sodalite zeolite with cetyltrimethylammonium (ZCTA). The presence of NiO increased the liquid product and the selectivity of the bioavtur fraction (C10-C15), where the highest percentage of liquid product was 60.07% at NiO/ZTPA.

“…Minyak cangkang kulit biji jambu mete (Cashew Nut Shell Liquid/CNSL) merupakan minyak nabati yang berwarna coklat kental kemerahan dan didapat dari hasil ekstraksi atau pengepresan cangkang kulit biji mete. Minyak ini memiliki kandungan utama yaitu asam anarkadat yang bersifat korosif dan pada umumnya tidak banyak digunakan oleh masyarakat (Ketaren dalam Efiyanti & Trisunaryanti 2014). Persebaran tanaman ini cukup banyak terutama di daerah Indonesia bagian Timur serta pada lahan kering, hal ini dikarenakan tanaman ini tahan panas dan dapat hidup di lahan marginal sehingga dapat juga digunakan sebagai tanaman pada rehabilitasi lahan (Efiyanti &Trisunaryanti, 2014).…”

Bioenergy is new and renewable alternative energy which is currently developed enthusiastically. Bioenergy could be produced by catalytic cracking method, which is cracking carbon chain to raise energy fraction. This paper observes potential non-food bioenergy of cashew nut shell liquid as an alternative bioenergy source using catalytic cracking method. The effect of impregnated-metals Nikel and Molibdenum catalyst used in hydrocracking of Cashew Nut Shell Liquid (CNSL) into bioenergy was investigated. It focused specifically on two type of natural activated zeolite catalysts: NiO and NiOMoO at o temperature reaction of 450 C and ratio feed catalyst of 2 and 4. Catalysts characterization was conducted according to a gravimetric method to determine acidity of catalyst; Spectroscopy FT-IR analysis to get distribution of active site catalyst; X-Ray Diffraction (XRD) analysis to observe crystalinity of catalyst; and Gas Sorption Analyzer (GSA) to measure surface area, porosity and total of pore volume. Bioenergy of CNSL in the liquid-phase, which were predominantly by gasoline, diesel oil, and heavy oil, was further analyzed using Gas Chromatography-Mass Spectrometry (GC-MS) to determine the compound energy fraction qualitatively and quantitatively. The result showed that the NiOMoO (natural activated zeolite) provided an optimal performance with liquid product conversion was about 65-75%, and selectivity gasoline as well as diesel fraction was about 37-47% and 22-31%, respectively.
