Effect of the Temperature on the product yield during the Pyrolysis of Guinea-Corn stalk

This study explain the effect of temperature on the product yield of guinea-corn stalk (Char, tar and Gas). Approximately 0.23kg dried Guinea Corn Stalk (GCS) was introduced into the retort in which the retort was rendered airtight. The retort was placed into the chamber of an electric furnace and the GCS was pyrolysed at a temperature of 400OC at a constant time of 20minutes. This was repeated for temperatures 450,500,550 and 600OC and in each cases, the quantities of char, tar and the bio-gas were determined. Proximate and ultimate analysis were carried out on the sample in other to know the level of moisture content in the sample and also to know if GCS has more contribution to global warming by observing the percentage of the Sulphur and Nitrogen content in the ultimate analysis.Using the sigma plot application as well as the Microsoft excel bar chart to illustrate the relationship between the temperature and the pyrolysis product. This application depict and shown how the increase in temperature affect the product yield (Gas, Tar and Char). The Char yields a percentage of approximately 17% at 400OC and drastically decreased to 27% at 600OC, the tar yields a percentage of approximately 28% at 400OC and increased to 39% at 600OC and also the gas yields a percentage of approximately 17% at 400OC and increased to 34% at 600OC.The result shown that GCS can be pyrolyzed at and high temperature to obtaining more yields of bio-gas.
