Abstract

This study aims to explore the possibility of creating enormous added value on coconut fiber resources which was so far considered as wastes. One of the added values of coconut fiber that can be created is bio-oil which rich in aromatic compounds. The rich-aromatic compounds within bio-oil has been produced successfully by the catalytic pyrolysis process which supported by impregnated ZSM-5 catalyst of Nickel and Zinc. Pyrolysis is a non-oxygen thermal cracking of organic materials. Pyrolysis product or known as bio-oil is used as an alternative fuel. However, as the era progresses bio-oil can be used as raw materials in manufacturing process of many petrochemical products because it has aromatic compounds. Aromatic is a shaped-ring chemical substance that can be found in lignocellulosic-rich biomass. Aromatic bio-oil is obtained from catalytic pyrolysis process of waste coconut fiber with the aid of using catalysts to maximize the composition of aromatic compounds. Coconut fiber is cut and grind in pre-treatment to the desirable size. Impregnated catalysts Zn/ZSM-5 and Ni/ZSM-5 that have been characterized by XRD (X-Ray Diffraction) are used to maximize the yield of aromatic compounds. The catalytic pyrolysis process takes place in a fixed bed tubular reactor equipped with a furnace as a heat source. The product coming out of the reactor is condensed by using cold water and acetone. FTIR (Fourier Transform Infrared) and GCMS (Gas Chromatography-Mass Spectrometer) serve as analytical instruments in order to identify the presence and the quantity of aromatic group in bio-oil. BTX (Benzene, Toluene and Xylene) as aromatic compounds within bio-oil has been identified through the FTIR analysis. Nickel of 5% weight loading is the main active component within impregnated ZSM-5 catalysts due to its performance in producing the highest yield of aromatic bio-oil as of 38.90%, at the reaction temperature of 450°C.
