Effect of Preheating the Gasifying Inlet Air on the Hydrogen Output in Oil Palm Fronds Gasification

Abstract:

Hydrogen is one of the most abundant elements in the universe and a clean carrier of energy. However, the existence of hydrogen is in different compound forms, in which a great deal of energy is required to split from the compounds. Gasification of biomass is one of the best methods to produce hydrogen. This study focuses on the production of hydrogen in gasification process by using a throated downdraft gasifier and preheated air as gasifying agent. For the study on the effect of gasifying air temperature on hydrogen concentration in the syngas an electric heater was used to preheat the inlet air up to 500°C. The results of the study showed that increasing the gasifying air temperature from 30°C to 500°C increased the volume concentration of hydrogen by 25.1% in the syngas. The increase in hydrogen was steeper when the inlet air was in the lower range temperature (30 to 265°C) as compared to that of the upper range (265 to 500°C).
