“…Pada penelitian ini digunakan logam Ni (nikel) untuk diimpregnasi ke dalam zeolit ZSM-5. Logam nikel yang diimpregnasikan ke dalam pori-pori zeolit akan meningkatkan jumlah situs asam dari zeolit (Rahayu et al, 2013). Logam nikel dan molibdenum biasa digunakan sebagai logam yang diembankan karena memiliki sifat katalitik sebagai inti aktif katalis (Kordouli et al, 2018).…”

dikonversi menjadi berbagai macam produk material baru yang mempunyai nilai tambah maupun berupa bahan bakar alternatif (Qadariyah et al., 2009).Produk material baru dari konversi gliserol dapat berupa metanol, alil alkohol, etanol, asetaldehid, karbon monoksida, propionaldehid, acrolein, formaldehid, hidrogen, dan karbon dioksida (Bühler et al., 2002). Beberapa penelitian telah dilakukan dalam mengkonversi gliserol menjadi senyawa lain. Qadariyah et al (2009) melakukan degradasi gliserol dengan gelombang mikro secara batch. Produk yang dihasilkan adalah etanol dengan persen yield tertinggi sebesar 6,764% yang diperoleh pada waktu 15 menit dan power 600 Watt. Ulfah. M. dan Sofianti.

“…Untuk zeolit alam aktif Ende menunjukkan bahwa luas permukaan berubah RBAET 17 menjadi 74,57 m 2 /g, jejari rata-rata 20,21Å dan volume pori 72,34 cc/g. Berdasarkan hasil analisis BET, juga diketahui secara kuantitatif aktivasi berhasil merubah zeolit menjadi zeolit mesopori (ukuran pori 2 -50 nm) [20].…”

Penelitian ini bertujuan untuk mengkarakterisasi zeolit Ende menjadi katalis pada pirolisis polietilena dari sampah plastik; mengetahui pengaruh katalis zeolit alam Ende terhadap energi aktivasi pirolisis; mengetahui pengaruh suhu dalam pirolisis; mengetahui pengaruh katalis dalam pirolisis; mengetahui pengaruh interaksi antara suhu dan katalis dalam pirolisis. Berdasarkan hasil percobaan, maka diketahui bahwa proses aktivasi dapat merubah sifat kimia dan sifat fisika zeolit Ende meliputi kristalinitas, luas permukaan, volume pori dan jejari pori, serta keasamannya untuk dijadikan sebagai katalis; katalis zeolit mampu menurunkan energi aktivasi hingga 4.371,1 cal/mol; komposisi 0,10 merupakan komposisi terbaik dari penggunaan zeolit alam aktif Ende sebagai katalis dalam proses pirolisis polietilena dari sampah plastik; interaksi terbaik antara suhu dan katalis zeolit alam aktif Ende adalah pada perlakuan suhu 400°C dan komposisi katalis 0,10.

“…Addition of 10%Fe to HY zeolite increased Lewis acid site, catalyst acidity density, surface area and mesoporous volume. Rahayu et al [9] reported that the acidity of Ni-zeolite increased 12 times compared to activated zeolite, the percentage of crystallinity increased by 7.40% in the presence of metal. Ni in atomic form and the use of a Ni-zeolite catalyst increased the yield of bio-oil by 40.38% compared to the active zeolite.…”

Metal loading on zeolite to produce bifunctional catalysts is reported to increased the characteristics of zeolites which synergistically increase their catalytic activity. Sarulla natural zeolite (SNZ) from North Sumatera has the potential as a catalyst because of its excellent chemical properties including acidity, thermal stability, and large pores. On the other hand, natural zeolite contains a lot of impurities and lower acidity density so that it needs to be processed before use. In this research, modification of the acidity density of zeolite and metal loading were expected to improve the characteristics of SNZ as a catalyst. To achieved this goal, the research methods carried out include preparation, activation process with mineral acid with various concentrations of 3M, 5M, and 7M, then calcination with N2 gas flow. Ni and NiMo loading by wet impregnation method followed by oxidation and reduction with O2 and H2 gas flow, respectively. Some important properties of the catalyst were characterized by XRD, SEM, and determination of surface area by BET method. Ni/SNZ-7 catalyst showed the largest spesific surface area (92 m2/g), the least impurities (3%), and the most homogeneous surface morphology compared to other catalysts. The deposition of two metals in the zeolite generally causes an increase in the pore diameter and crystallinity degree, while decreasing in the pore volume of catalyst.
