Abstract

Artikel ini menjelaskan definisi pirolisis dan pentingnya proses pirolisis dalam konversi termokimia biomassa menjadi bahan bakar. Teknologi pirolisis berpotensi untuk dikembangkan karena ketersediaan sumber bahan biomassa yang sangat melimpah, teknologinya mudah untuk dikembangkan, bersifat ramah lingkungan dan menguntungkan secara ekonomi. Dalam teknik pirolisis, beberapa parameter yang mempengaruhi proses pirolisis adalah perlakuan awal biomassa, kadar air dan ukuran partikel bahan, komposisi senyawa biomassa, suhu, laju pemanasan, laju alir gas, waktu tinggal, jenis pirolisis, jenis reaktor pirolisis dan final produk pirolisis. Reaktor pirolisis adalah alat pengurai senyawa-senyawa organik yang dilakukan dengan proses pemanasan tanpa berhubungan langsung dengan udara luar dengan suhu 300-6000C. Beberapa jenis reaktor pirolisis yang sering digunakan adalah Fixed-Bed Pyrolyzer, Bubbling Fluidized-Bed Reactors, Circulating Fluidized Bed, Ultra–Rapid Pyrolyzer, Rotating Cone, Ablative Pyrolyzer dan Vacuum Pyrolyzer. Teknik pirolisis menghasilkan tiga macam produk akhir, yaitu bio-oil, arang (biochar) dan gas.

Abstract

Coconut shell is a solid waste of biomass from processed coconuts separated from the flesh. Coconut shells can be reprocessed into products of high economic value. Coconut shells can be processed for bio-oil production via high-temperature pyrolysis. In the pyrolysis process, the coconut shell raw materials are reduced in size to facilitate combustion. The aim of this research was to test the performance of the modified coconut shell grinding machine, determine the effect of water content on the milling process, achieve coconut shell sizes of 3, 5, and 10 mm to enhance the pyrolysis process, and analyze the economics of grinding machine engineering. The size reduction process was carried out using a custom-designed coconut shell grinder that was altered in its sieve section. The sieve sections had diameters of 10, 5, and 3 mm. The coconut shell to be ground had a moisture content of 8–10%. The grinding machine capacity varies with each size, namely 10 mm, 5 mm, and 3 mm, achieving throughput rates of 14.892 kg/h, 7.214 kg/h, and 2.94 kg/hour, respectively. The resulting yield was notably high, ranging from 95 to 96.780%, and the associated yield loss remained low, between 3.2% and 4.8%. During the material size tests, the working RPM was observed at 630.6 for 10 mm, 711.2 for 5 mm, and 1017.18 for 3 mm, and these RPM variations influence the grinding speed.
