Zeolit-Y sintetik dimodifikasi dengan menambahkan amonium nitrat 2 M, dan dikalsinasi selama 5 jam pada suhu 450°C. Kemudian, produk diimpregnasi dengan nikel klorida dalam etanol. Konsentrasi larutan klorida nikel masing-masing adalah 0,4%, 0,6%, 0,8%, 1,0%, 1,2% dan 1,6%. Karakter Ni/zeolit-Y dan H/zeolit-Y diperoleh dengan mengukur kandungan nikel dan kristalinitas. Pengujian aktivitas katalis dilakukan menggunakan proses hydrorengkah pada suhu 350°C dan menggunakan umpan fraksi 150-230°C dari minyak mentah Minas. Produk perengkahan cair dianalisis dengan kromatografi gas-spektroskopi massa (GC-MS). Hasil penelitian ini menunjukkan bahwa ada peningkatan kandungan nikel pada H/zeolit-Y setelah proses impregnasi. Dari pengukuran kristalinitas, diketahui bahwa kristalinitas relatif H/zeolit-Y setelah impregnasi menurun sekitar 26 - 28%. Uji aktivitas menunjukkan bahwa Cairan Hasil Perengkahan (CHP) tertinggi sebesar 55% (diisikan Ni 2,51%). Selain itu, kami mendapat informasi bahwa Ni/zeolite-Y dapat mengubah senyawa C 13 -C 23 dari umpan dan menghasilkan fraksi C 7 -C 10 sebagai senyawa baru.}, issn = {2597-9914}, pages = {81--88} doi = {10.14710/jksa.8.3.81-88}, url = {https://ejournal.undip.ac.id/index.php/ksa/article/view/17515} }
