Abstract

Waste tires are very difficult for biological degradation because it takes a long time to breakdown and can pollute the environment. One way to handle waste tires to make them have an added value is by pyrolysis process. In waste tires, there are long hydrocarbon chains that can be turned into short chains. The purpose of this study to determine effect of pyrolysis time on the yield of pyrolysis products from motorcycle waste tires using natural zeolite as catalysts. The pyrolysis process was carried out by adding 1000 grams of waste tires in 2x2 centimeters and 60 grams of activated natural zeolite with pyrolysis time variations of 1,5h, 2h, 2,5h, 3h, and 3,5h a pyrolysis temperature of 400oC. The best results are purified by the catalytic pyrolysis process. Pyrolysis liquid product was measured for the yield and analyzed Gas Chromatography- Mass Spectrometry (GC-MS). Pyrolysis time of 2,5h produced the highest liquid yield 58.77%, which had chains (C5-C10) as much as 37.41%, (C10-C16) as much as 26.26%, (C14-C20) as much as 32.22%, and (>C20) as much as 4.12%. The most hydrocarbon chain in pyrolysis liquid (C5-C10) 37.41% as the gasoline fraction. The refining process can increase the yield of gasoline fraction 74.83%. Key words: waste tires, natural zeolite catalyst, pyrolysis
