Abstract:
Selecting appropriate bed material in fluidized bed gasification is a vital consideration that is often overlooked. Ideally, bed material should be low-cost, capable of withstanding high temperatures, and exhibit limited chemical reactivity with biomass. However, attention is frequently given solely to the economic aspect, neglecting the high-temperature interactions between biomass and bed material. In this study, olivine and K-feldspar were tested at scale in a prototype fluidized bed gasifier (FBG) using tree biomass (almond shells). The resulting syngas from each test was analyzed and compared based on its composition in contaminants, including volatile organic compounds (VOCs), tars, and metals. Additionally, the chemical composition of olivine and K-feldspar was assessed before and after gasification. This research aims to identify the benefits and drawbacks associated with selecting the most suitable bed material and to refine the biomass gasification process by minimizing unwanted outcomes, such as the generation of heavy metals, bed material agglomeration, and tar formation.
