Abstract

Etilen sebagai produk petrokimia yang penting dapat dibuat dari bioetanol menggunakan katalis ZSM5. Zeolit sintetis ZSM5 dapat dibuat menggunakan zeolit alam yang banyak tersedia di Indonesia. Proses pembuatan ZSM5 menggunakan metode hidrotermal pada temperatur 180°C selama 24 jam. Sebagai agen pengarah terbentuknya struktur ZSM-5 tersebut digunakan template TPABr (Tetra Prophyl Ammonium Bromide). Kalsinasi produk ZSM5 dilakukan pada temperatur 600°C selama 1 jam. Karakterisasi ZSM-5 yang dilakukan antara lain analisis struktur dan kristalinitas, observasi morfologi permukaan menggunakan metode Difraksi Sinar X, Scanning Electron Microscopy, dan physisorption untuk mempelajari sifat pori. Hasil penelitian menunjukkan bahwa dihasilkannya ZSM-5 dengan kristalinitas sekitar 110 %. Kristal ZSM-5 yang dihasilkan berbentuk kubus dengan luas permukaan spesifik BET 300 m2/g, volume pori sekitar 0,13 Cm3/g. Distribusi ukuran pori yang sempit mengindikasikan ukuran pori yang seragam dengan ukuran rata-rata 0.55 nm.

Abstract

Production of Crude Palm Oil (CPO) is increasing from year to year and is predicted to reach 41.6 million tons per year in 2018. Each ton of CPO will produce 3,28 m3 of POME during the production process. Improper handling of POME, besides causing soil pollution and flying, will release methane gas that categorized as GHG. BPPT cooperate  with PTPN V utilized POME to produce biogas and then be converted into electricity in a Biogas Power Plant (PLTBg) in Terantam with a design capacity of 700 kW. The reactor used is a closed Anaerobic Lagoon (CAL) reactor equipped with a recirculation pump. From the evaluations, the technology chosen was not optimal from the operation, its evaluaed from the accumulation of cakes and sludge collected in the reactor which could be disturb during an anaerobic reaction. The next technology development will be carried out with the development of PLTBg in Sei Pagar using CSTR technology. At the same reactor capacity, CSTR has a faster HRT compared to CAL. CSTR is also easier in control of pH and temperature, also requires less land.Keyword : POME, Biogas, CSTR, Covered Lagoon, HRT, OLR
