Biomass Gasification of Pongamia char in a Fluidized Bed Reactor

This research is about gasifying the biomass char in a fluidized bed gasifier and yielding Syngas. Biomass char was obtained after pyrolysis of Pongamia in a fixed bed reactor. During the gasification, air was used as an oxidizing agent. The resulting gas contained a mixture of hydrogen, carbon dioxide and monoxide, methane, ammonia, oxygen, low concentrations of elevated hydrocarbon emissions, pollutants, including small bits of char etc. The hydrogen thus produced is taken out and can be used as a potential fuel because of a source of clean energy and an alternative carbon supply. In today's scenario, the generated syngas has many applications. This paper explores the biomass air-steam gasification dynamics of a fluidized bed. Several studies were carried out to explore effects from reactor temperature, vapor to biomass ratio (S/B) and biomass particulate content, gas emission, vapor and low heating (LHV). The findings indicate that a higher temperature contributed to a higher percentage of hydrogen production. There has also been evidence that a smaller particle is more suitable for higher gas and levels of LHV.
