Abstract


Catalytic pyrolysis of waste starch powder using active zeolite catalyst has been carried out. The purpose of this study was to determine the ratio of catalyst/feed and compare the optimum catalyst containing compounds pyrolysis bio-oil yield. Catalyst characterization performed using X-ray diffraction and N2 gas adsorption. Bio-oil is produced characterized using Gas Chromatography-Mass Spectroscopy (GC-MS) to determine the content of compounds of pyrolysis bio-oil yield. As a result, the acidity of the active zeolite catalyst of 0.003 mol / g, the mineral content of the zeolite is mordenite and surface area, mean diameter and total pore volume of the catalyst amounted to 199.115 m2 / g, 20.55 Å and 66.1445 cc / g. Bio-oil produced at the optimum ratio of catalyst/feed 6% with the content of the compound is acetic acid with an abundance of 29.48%. The selectivity of zeolite catalysts active in the formation of compounds, namely methanol, acetone 2-propanone, and 2-furanone.


Keywords
