Abstract—This research reports the energy release of rice chaff by pyrolysis. In Southeast Asia, rice is a staple food, and an abundance of chaff remains after rice cleaning the rice. Most chaff is spread on farmland or used as livestock feed. However, there is still a large amount of discarded chaff. In this study, This research was gasified chaff to evaluate its energy conversion using pyrolysis. This research investigated the effect of molecular sieves, which are a column filler, as an additive. The pyrolysis was performed under highly efficient conditions to measure any catalytic effects. Methane gas is a decomposition product and its release was the focus of this work as well as analyzing the amount of emitted carbon dioxide Adding molecular sieves 3A increases methane gas release and decreases carbon dioxide.

Index Terms—Molecular sieve, pyrolysis, rice husk.
