Abstract

Tanaman jambu mete, Anacardium occidentale L. merupakan salah satu komoditi perkebunan yang memiliki nilai ekonomi cukup tinggi. Kulit biji jambu mete mengandung 50% minyak yang terdiri dari senyawa fenolat berupa 90% asam anakardat dan 10% berupa kardol dan kardanol. Penelitian ini bertujuan untuk mensintesis dan mengkarakterisasi katalis Ag/zeolit, melakukan pirolisis kulit jambu mete, mengetahui pengaruh temperatur pirolisis terhadap produk cair pirolisis dan membandingkan produk cair hasil pirolisis yang menggunakan katalis zeolit dan Ag/zeolit. Penelitian dilakukan beberapa tahap yaitu pembuatan katalis Ag/Zeolit dan pirolisis kulit biji jambu mete. Pirolisis dilakukan dengan katalis Ag/zeolit pada temperatur 200, 250, 300, 350, dan 400°C. Karakterisasi katalis menggunakan Surface Area Analyzer, AAS, uji keasaman dan GC-MS untuk produk cair pirolisis. Hasil penelitian diperoleh katalis Ag/zeolit yang mengalami penurunan luas permukaan spesifik sebesar 70,28%, volume total pori sebesar 70,19%. Nilai keasaman katalis Ag/zeolit mengalami kenaikan sebesar 50%, mengandung logam Ag sebesar 0,6326%. Hasil analisis GC-MS produk cair pirolisis pada temperatur 400°C dengan katalis Ag/zeolit diperoleh senyawa 3-octylphenol dengan kelimpahan sebesar 72,28%, dengan katalis zeolit alam teraktivasi dihasilkan senyawa 3-(pentadec-8-enyl)phenol dengan kelimpahan sebesar 77,04%.
