The effect of residence time and temperature on product yields during the pyrolysis of coconut husks

Abstract

This study explains the effect of residence time and temperature on product yield obtained from Coconut husks' pyrolysis. The husk of the coconut was prepared in the required sizes for the experiment. The experiment was carried out on eighteen different coconut husks at different temperature ranges and varying residence time. The coconut husk pyrolysis was confirmed to give three product yields: char (solid), tar (liquid), and the gaseous fuel, while a polynomial regression model was developed using the Response surface methodology (RSM) to create a polynomial regression model. The effect of pyrolysis temperature level change and its product yield duration was investigated using Full Factorial Design (FFD). Generally, during the pyrolysis process, it can be observed that temperature and reaction time have a strong outcome on the product yields. When the pyrolysis temperature increases at constant residence time, the biogas production increases, and vice versa.
