| Summary: | Municipal household garbage has greatly increased in recent years, so that reducing waste mass becomes an important issue to address. Direct landfilling, sanitary landfilling, composting, and incineration, because of their disadvantages, are gradually replaced by pyrolysis. Pyrolysis technology applies new methods to convert organic waste into bio-oil.<p> <br />

Pyrolysis is a high temperature process in the absence of oxygen. The process of fast pyrolysis is one of the most recent renewable energy processes to have been introduced. Compared to combustion and gasification, which is widely practiced commercially, fast pyrolysis is at relatively early stage of development. The technology has now achieved some commercial success for production liquid fuels.<p> <br />

This research aims to design pyrolysis reactor, develop pyrolysis operating procedure, and to investigate the effect of pyrolysis temperature to liquid product quality. The pyrolysis experiments will be performed in two cylindrical batch reactors. The first is equiped from carbon steel with 13 cm inside diameter and 25 cm height. The second is glass reactor with 5 cm inside diameter and 40 cm height. The feed is sawdust. The experimental conditions are as follows: temperature range 300-450 degrees C, and reaction time 30-60 min. The effect of catalyst Zeolit to liquid product quality will also be observed.<p> <br />

The crude pyrolysis liquid is dark brown. The pyrolysis liquid yield increase with the increase of the temperature and its composition becomes more variative. The chemical characterization by using Fourier Transform Infrared (FT-IR) and Gas Chromatography Mass Spectrometry (GC-MC) showed that the pyrolysis liquid products contain large amounts of water and few contents of carboxylic acids and aromatics compound. The result are very similiar to bio-oils obtained from other biomass pyrolysis. |
