Hakim, Arief Rahman (2017) Pengaruh Variasi Temperatur Terhadap Produk Char Pada Pirolisis Serbuk Kayu Mahoni Dengan Katalis Zeolit 75%. Sarjana thesis, Universitas Brawijaya.
Abstract
Zeolit diketahui sebagai katalis pirolisis yang efektif dalam mengoptimalkan hasil dekomposisi termal biomassa. Char merupakan salah satu produk pirolisis yang berwujud padatan. Tujuan penelitian ini adalah mengidentifikasi produk char hasil pirolisis serbuk kayu mahoni dengan campuran zeolit sebesar 75%. Dalam penelitian ini menggunakan variasi temperatur 250°C, sampai dengan 800°C. Proses pirolisis ini dilakukan selama tiga jam tanpa oksigen dengan bahan baku serbuk kayu mahoni sebanyak 200 gram dengan ukuran 0,833 mm (mesh 20) serta kadar air < 2%. Hasil penelitian diuji kadar unsur dan gugus fungsinya dengan menggunakan perangkat SEMEDX dan FT-IR. Dari hasil penelitian menunjukkan bahwa semakin tinggi temperatur pirolisis akan menurunkan massa dan volume produk char terlebih lagi untuk pirolisis 75% zeolit. Produk char hasil pirolisi menunjukan peningkatan kadar karbon (C) seiring dengan pertambahan temperatur pirolisis. Hasil analisa FT-IR menunjukan hilangnya gugus karbonil C=O pada char hasil pirolisis campuran zeolit 75%, dan munculnya gugus alkena C=C pada char hasil pirolisis campuran zeolit 75%
English Abstract
Zeolite is known as a pyrolysis catalysts which is effective in optimizing the yield of thermal decomposition of biomass. Char is one of pyrolysis products in solid form. The purpose of this research is to identify the char product of mahogany powder with zeolite mixture of 75%. The research process undertaken experimentally with temperature 250 to 800oC. The pyrolysis process is done for three hours without oxygen. The mahogany wood powder has 200 gram, with a size of 0.833 mm (mesh 20) and air content less than 2%. The results of the research were tested for elemental content and functional groups by using SEM-EDX and FT-IR devices. The results showed that the higher pyrolysis temperature decreased the mass and volume of char products moreover for pyrolysis 75% zeolite. The pyrolysis char yield product showed an increased in carbon content (C) as the pyrolysis temperature increased. The result of FT-IR analysis showed the loss of carbonyl group C = O at char pyrolysis result of 75% zeolite mixture, and the appearance of C = C alkene group on char pyrolysis result of 75% zeolite mixture.
