Abstract

Fallen leaves of cherry and pine were put in a side-arm flask with zeolite. It was heated gradually by an infrared heater until 540 °C to generate ethylene gas. The amount of ethylene was measured by gas chromatography. Lignin reagent, filter paper, and newspaper were also used for comparison. The same experiment without zeolite was also conducted to check the effect of the zeolite. Ethylene gas began to generate at approximately 400 °C. 3.6% of the fallen leaves of cherry and 3.1% of the fallen leaves of pine turned into ethylene gas. The amount of ethylene gas generated from lignin reagent was about two-thirds of that from fallen leaves. The amount of ethylene gas generated from filter paper was little. The amount of ethylene gas generated from newspaper which was thought to contain lignin a little was larger than that from filter paper. By using zeolite, the smell of the phenolic compound were gone and the amount of ethylene gas increased.
