Hydrogen production from groundnut shell via circulating fluidized bed technology

Abstract

In this study, hydrogen production performances of groundnut shells in a circulating fluidized bed gasifier is evaluated by employing a previously developed and validated model. Basically, we simulate a circulating fluidized bed gasification system that is connected to a water-gas shift reactor, for hydrogen purification with the gasifier temperature of 1150 K. We find that the amount of hydrogen gas produced from circulating fluidized bed gasification of groundnut shells increases from 49.25 kmol to 68.83 kmol (per 1000 kg of raw groundnut shells) when the gasifier is integrated with water-gas shift reactor. We observe that it is possible to obtain a high yield of hydrogen gas from the gasification of groundnut shells. Therefore, we conclude that the groundnut shell is a remarkable feedstock for bioenergy.
